--- title: "Changelog" canonical_url: "https://www.nutrient.io/guides/ios/changelog/" md_url: "https://www.nutrient.io/guides/ios/changelog.md" last_updated: "2026-05-14T16:53:43.864Z" description: "Latest updates and release notes for Nutrient iOS SDK, including new features, improvements, and bug fixes." --- # Changelog for iOS ## 26.8.0 — 1 May 2026 See the [release notes](https://www.nutrient.io/guides/ios/releases/26-8.md). ### PSPDFKitUI * Improves UI responsiveness for complex documents by auto-saving in the background by default. This can result in conflict resolution alerts or data being overwritten if multiple instances of `Document` are created for the same file URL. See the migration section of the release notes for details. (J#IOS-974) * Improves UI responsiveness when low memory warnings are received while there are `Document` instances for complex files like building plans that aren’t being displayed by a `PDFViewController`. (J#IOS-774) * Fixes annotation reordering controls being included in the popover shown from the color button in the free text annotation editing toolbar. (Z#132373) * Fixes drawing signatures not working when setting `usePencilKit` to `true` and then `false` again on the same `SignatureCreationViewController`. (#51696) * Fixes drawn signatures being inverted in dark mode when `usePencilKit` is enabled. (#51696) ### PSPDFKit * Improves PDF redaction stability and memory usage for complex documents with nested shared forms and repeated standard-font parsing, reducing cases where applying redactions could consume excessive memory or fail to complete. (J#CORE-1062) * Improves performance for PDFs with large content streams. (J#CORE-1064) * Changes the document features `canUseDocumentEditor` and `canFillForms` to be disabled if the corresponding license features are disabled. (#52068) * Fixes Multiply/Overlay blend modes rendering too dark in DeviceCMYK transparency groups. (J#CORE-1058) * Fixes an issue where applying redactions could produce burned overlay text that didn’t honor the configured redaction font size. (J#CORE-1078) * Fixes corrupted rendering of indexed JPEG2000 image tiles in clipped renders. (J#CORE-948) * Fixes flattened annotations losing their blend mode, causing freeform highlights to appear opaque after export. (J#CORE-1065) * Fixes garbled text on non-redacted pages when a document uses shared font resources across pages. (J#CORE-1054) * Fixes incorrect text selection and highlighting for ligatures in some PDFs. (J#CORE-1077) ### Instant * Adds `InstantDocumentDescriptor.annotationOrderingComparator` and `InstantDocumentDescriptor.invalidateAnnotationOrdering()` for controlling local annotation presentation order in Instant-managed iOS documents. (J#IOS-1086) * Adds the `InstantError.isRetriableKey` user information key to indicate whether the Instant client will automatically retry syncing after a transient error. (J#IOS-49) * Changes Instant image and stamp annotations to render on the page instead of as overlays after loading their image data. (J#IOS-1086) * Fixes a race condition where concurrent Instant attachment download completions could fail. (J#IOS-1084) ## 26.7.0 — 2 Apr 2026 See the [release notes](https://www.nutrient.io/guides/ios/releases/26-7.md). ### PSPDFKitUI * Improves form interaction responsiveness in complex documents. (J#IOS-1026) ### PSPDFKit * Improves paragraph detection for content editing on PDF/UA documents. (J#CORE-1047) * Fixes a deadlock that could occur when opening documents with malformed form widget annotations. (J#IOS-1048) * Fixes a regression introduced in Nutrient iOS SDK 26.4 where orphaned widget annotations (form elements) wouldn’t be loaded by the form parser. For now, this reverts the performance improvement from that release referenced as #49773. (J#IOS-1101) * Fixes an issue where bold text could appear with the wrong style in some embedded-font PDFs on Apple platforms, which could change visual emphasis in customer documents. (J#CORE-993) * Fixes an issue where content editing didn’t update the modification date of the PDF. (J#CORE-1032) * Fixes an issue where repeated redactions on certain image-based PDFs could cause the page colors to toggle or appear inverted. (J#CORE-989) * Fixes an issue where text annotations with certain fonts, like Calibri, are incorrectly rendered when used in multiple lines, making them overlap. (J#CORE-1021) * Fixes content editing mismatch warnings to show the original PDF font name instead of the substituted fallback font. (J#CORE-1048) * Fixes garbled text in form fields when the field’s font is a CID font subset without the standard subset naming convention. (J#CORE-1042) * Fixes incorrect text placement when editing tagged PDFs by preserving text in the correct content stream graphics state. (J#CORE-1033) * Fixes ink highlighter export rendering when using a background color with multiply blend mode. (J#CORE-951) * Fixes note annotations with a larger size appearing offset, especially at higher zoom levels, improving placement consistency across platforms. (J#IOS-1078) ### Instant * Fixes a crash that could occur when opening Instant documents with many image attachments. (J#IOS-1083) * Fixes a potential main thread hang when resizing or moving annotations with a note while Instant syncs changes from the server. (J#IOS-1080) ## 26.6.0 — 5 Mar 2026 See the [release notes](https://www.nutrient.io/guides/ios/releases/26-6.md). * Nutrient iOS SDK now requires and is built with Xcode 26.3. ### PSPDFKitUI * Deprecates `SignatureCreationViewController.drawView`, which is unsupported when using PencilKit for signing. If you’re using this API, [let us know how](https://www.nutrient.io/support/request) so we can provide a replacement that works with PencilKit. (#48861) * Adds the option to use Apple PencilKit for handwritten signatures (the `Draw` mode of `SignatureCreationViewController`) to improve the look and feel. Enable by setting `usePencilKit` to `true` in the signature creation configuration. If enabled, the `drawView` property of `SignatureCreationViewController` will raise a fatal error if read. (#48861) * Fixes an incorrect assertion when setting a spacer in both the left and right bar button items of `NavigationItem`. (#50526) * Fixes callout free text annotations showing an oversized text box while editing on rotated pages. (J#IOS-970) * Fixes custom tab bar appearance being reset to system defaults when presenting `PDFView` inside a `TabView`. (J#IOS-776) * Fixes the close button being missing on `AnnotationTableViewController` when `allowEditing` is disabled. (J#IOS-1000) ### PSPDFKit * API: Changes copying an `Annotation` with `NSCopying` so the copy has a different `uuid`. This is consistent with the `uuid` being a stand-in for object identity. This makes it possible to add copied annotations to a document. (J#IOS-781) * Deprecates `PSPDFProcessorAnnotationTypesKey`, `PSPDFProcessorAnnotationDictKey`, and `PSPDFProcessorAnnotationAsDictionaryKey`. Instead, first generate the PDF, and then add annotations. (J#IOS-781) * Fixes XFDF export being truncated when PDF annotations contain text encoded in Latin-1 (`PDFDocEncoding`) with characters that map to embedded null bytes. (J#CORE-1015) * Fixes a content editing exception caused by embedded fonts with an empty or null font span which prevented editing text in certain documents. (J#CORE-1020) * Fixes a crash when merging PDFs where the first document has a malformed `StructTreeRoot` (`ParentTreeNextKey` without `ParentTree`). (J#CORE-1013) * Fixes an infinite recursion when saving annotations in documents with unresolved GoTo action destinations from external files. (J#IOS-1069) * Fixes destination resolution for link annotations and outlines in PDFs with large name trees. (J#CORE-662) * Fixes indexed full-text search returning no results when the search term contains special characters such as `&`, `/`, `:`, or `+`. (J#CORE-1030) * Fixes text extraction for Type 3 fonts that use standard glyph names in their encoding but lack a ToUnicode CMap. (J#CORE-1018) ### Instant * Fixes an app hang when editing a free text annotation while Instant syncs changes from the server. (J#IOS-1058) * Fixes an app hang when moving or resizing an annotation while Instant syncs changes from the server. (J#IOS-1059) ### Examples * Adds a Catalog example showing straightening ink annotations, including freeform highlighter. (#49438) * Improves `AdaptivePDFViewController` in Catalog (used in the playground example) to show more main toolbar buttons, with buttons collapsing into a menu on iOS 26+ when there isn’t enough space. (#48618) * Removes `PSCObjectiveCExample.m` in Catalog because it doesn’t cover any concepts not shown by `PlaygroundExample.swift`. The SDK’s support for Objective-C remains unchanged. (#50803) ## 26.5.0 — 12 Feb 2026 See the [release notes](https://www.nutrient.io/guides/ios/releases/26-5.md). ### PSPDFKitUI * API: `DrawView.drawGestureRecognizer` is no longer automatically attached to any view. If you’re creating instances of `DrawView`, manually attach this gesture recognizer to the `DrawView`. (J#IOS-648) * Deprecates `KeychainAnnotationSetsStore`. If the security provided by the keychain is important to you for annotations, [contact us](https://nutrient.io/support/request/). If not, switch to using the default store for saved annotations (`PersistentAnnotationSetStore`). (#50098) * Adds support for encrypted documents with AI Assistant (server). (J#IOS-987) * Fixes text selection not working while annotating using Apple Pencil. (J#IOS-648) * Fixes `BookmarkIndicatorButton` not displaying the bookmarked state correctly. (J#IOS-1021) * Fixes `SavedAnnotationsViewController` not working when created in a storyboard. (#50096) * Fixes a crash in Document Editor when rapidly modifying pages in documents with large numbers of pages. (J#IOS-414) * Fixes a crash when reading the `annotationStore` property of a programmatically created `SavedAnnotationsViewController` without first setting that property. (#50096) * Fixes descendants of the `PDFBaseViewController` class not responding to text size changes when created in a storyboard. (#50096) * Fixes the `toggleUserInterface` interaction consuming events (with no effect) when the user interface can’t be toggled. (Z#128868) * Fixes the page rendering progress indicator sometimes not appearing for some PDFs. (J#IOS-929) ### PSPDFKit * Deprecates the `DataProviding` method `deleteData() throws` and all implementations of this method. This isn’t used by Nutrient. (#50103) * Adds support for [Brotli decompression](https://pdfa.org/brotli-compression-coming-to-pdf/). (J#CORE-1006) * Improves display of JavaScript alert messages. (J#CORE-980) * Improves Instant JSON import and export by using the same form field IDs from imports in subsequent exports. (J#CORE-964) * Improves rendering of highlight annotations over text with small line heights by not doubling the fill where lines overlap. (J#CORE-641) * Fixes an issue where certain typographic ligatures (ti, ct, ck) encoded as Private Use Area code points would appear as garbled text when copying from PDFs. (J#CORE-1005) * Fixes an issue where text markup annotations and redactions would shift incorrectly after applying page margins. (J#CORE-1003) * Fixes a crash when flattening PDFs with note annotations that contain missing character glyphs. (J#CORE-973) * Fixes execution of OpenAction JavaScript in PDF files. (J#CORE-980) * Fixes rendering of special Unicode characters in text form fields that were erroneously classified as emojis. (J#CORE-836) ### Examples * Adds a Catalog example showing single taps performing a custom action instead of toggling the user interface. (Z#128868) ## 26.4.0 — 14 Jan 2026 See the [release notes](https://www.nutrient.io/guides/ios/releases/26-4.md). * Nutrient iOS SDK now requires and is built with Xcode 26.2. ### PSPDFKitUI * Adds a `shouldInsetContentForUserInterface` configuration property to inset document pages so they aren’t covered by the user interface (toolbars). (Z#129596) * Adds a progress indicator (spinner) to the outline view. (Z#125363) * Changes the AI Assistant button to be shown when using on-device AI Assistant and when Apple Intelligence is enabled but not yet ready. In this case, an alert will be shown to provide more feedback to the user. (#49940) * Fixes the Save item in the menu for selected annotations (which saves into `SavedAnnotationsViewController.sharedAnnotationStore`) being shown when the document’s `annotationSaveMode` is `.disabled`. While saving to the global store is still possible for a read-only document, this could be a confusing user experience since the saved annotations couldn’t be added back into the document. (J#IOS-552) ### PSPDFKit * Improves time to see rendered pages in documents with large outlines. (Z#125363) * Improves performance when opening documents, which will be noticeable when there are thousands of pages or annotations. (#49773) * Fixes `GoToAction.pageIndex` sometimes returning `NSNotFound` when called from two or more threads concurrently. (#49770) * Fixes an issue where importing Instant JSON from multiple threads at the same time could cause a crash. (J#CORE-983) * Fixes XFDF export of note annotations incorrectly setting the note color as the text color, which could, for example, result in yellow text on a yellow background. (J#CORE-978) * Fixes an issue where the font bounding box was written incorrectly. (J#CORE-985) * Fixes an issue where unrelated text was appended to automatically extracted links. (J#CORE-969) ## 26.3.0 — 11 Dec 2025 See the [release notes](https://www.nutrient.io/guides/ios/releases/26-3.md). * Nutrient iOS SDK now requires and is built with Xcode 26.1.1. ### PSPDFKitUI * Adds support for fractional values in measurement scale and calibration inputs. (J#IOS-786) * Improves UI responsiveness in complex documents by fixing a case where accessibility could trigger annotation loading on the main thread. (J#IOS-774) * Improves UI responsiveness in complex documents when scrolling or zooming by fixing an issue where reading from the render cache might wait for background operations. (J#IOS-870) * Improves performance when opening documents with very large numbers of pages and using `PageMode.automatic`. (Z#125363) * Fixes a crash when navigating to a page with a page-open trigger action that goes to the same page or loops through a cycle of pages. (J#IOS-970) * Fixes crashes that could occur when using Document Editor (NSInternalInconsistencyException: Attempted to modify the selection of an out-of-bounds item). (#49560) * Fixes the eraser tool sometimes appearing to not erase after scrolling back to a page with ink annotations. (J#IOS-727) * Fixes the sharing UI not appearing when the sharing configuration resulted in no choices for the user to make. This regressed in Nutrient iOS SDK 26.0. (J#IOS-982) ### PSPDFKit * API: `Document.documentProviderForPage(at:)` now returns `nil` for locked, single-provider documents instead of returning that single provider. This is to be consistent with locked documents not having a known number of pages so no page index is valid. Use `document.documentProviders.first` to get the provider instead. (#49675) * Adds support for fractional input on each side of a measurement scale (e.g. 1/2, 3/4, 1 3/4) with the new `formattedFrom` and `formattedTo` properties on `MeasurementScale`, which are strings instead of floating-point values. (J#IOS-786) * Improves font selection when working with PDFs with invalid font descriptors (Identity-H without embedded font). (J#CORE-965) * Improves text rendering when working with PDFs with invalid font descriptors (Identity-H without ToUnicode - Arial, Arial Narrow, Lucida Sans, Times New Roman, Trebuchet). (J#CORE-961, J#CORE-958) * Fixes a crash when redacting form fields. (J#CORE-977) * Fixes an issue where the wrong objects were preferred when rebuilding cross-reference tables. (J#CORE-972) * Fixes freezes that could occur when opening documents with forms that needed fixing due to form elements with missing fields. (J#IOS-966) * Fixes ligature character coordinates in text selection when PDFs use `ActualText` marked content. (J#CORE-930) * Fixes the `Document` methods `documentProviderForPage(at:)`, `pageInfoForPage(at:)`, `textParserForPage(at:)`, and `pageLabelForPage(at:substituteWithPlainLabel:)` sometimes returning data for another page instead of `nil` when the page index parameter is greater than or equal to the number of pages in the document. (#49675) ### Examples * Adds the `CustomThumbnailViewControllerExample` Catalog example on changing fonts in `ThumbnailViewController`. (#49092) * Adds the `AlwaysShowAnnotationToolbarExample` Catalog example that keeps the annotation toolbar visible instead of it being toggled by the annotation button in the main toolbar. (Z#129213) ## 26.2.0 — 14 Nov 2025 This release adds on-device AI Assistant using Foundation Models, which enables asking questions about documents with a chat interface. See the [release notes](https://www.nutrient.io/guides/ios/releases/26-2.md). ### PSPDFKitUI * Deprecates `blurEffectStyle` and `buttonStyle` on `StyleButton` and the `StyleButton.Style` enum in favor of a more modern appearance using glass on iOS 26. (J#IOS-840) * Deprecates `blurEffectStyle` and `labelStyle` on `PDFLabelView` and the `PDFLabelView.Style` enum in favor of a more modern appearance using glass on iOS 26. (J#IOS-840) * Adds on-device AI Assistant. This feature is supported on devices with Apple Intelligence enabled and can be accessed by adding `AIAssistantButton` or `aiAssistantButtonItem`. [Learn more in our guides.](https://www.nutrient.io/guides/ios/ai-assistant/on-device.md). (J#IOS-805) * Adds a glass background to `PDFLabelView`, which is used as a page label, as a document label, and for showing inline search results. (J#IOS-840) * Adds a glass background to `StyleButton`, which is used for the back and forward navigation buttons, the redaction information button, and the measurement scales button. (J#IOS-840) * Adds suggested questions support for AI Assistant while using multiple documents. (Z#127980) * Improves loading performance when reopening AI Assistant from the document view. (J#IOS-964) * Improves specificity of error messages in AI Assistant (server). (#49329) * Updates `TextStampViewController`, `PDFDocumentSecurityViewController`, and `PDFDocumentInfoViewController` to use the `.insetGrouped` table view style to modernize the UI. (#49186) * Fixes an issue where the custom title set for `AIAssistantViewController` could be overridden. (#48932) * Fixes popovers automatically resizing when the color picker for selecting annotation colors is shown, which sometimes caused issues with it expanding too much. (J#IOS-943) ### PSPDFKit * API: Adds `Equatable` conformance to `AIAssistantConfiguration` for configuration equality checks. (#49187) * Adds support for preserving accessibility tags when using Content Editor. (J#CORE-946) * Improves rendering of dashed lines. (J#CORE-924) * Improves support for using embedded fonts with Content Editor. (J#CORE-939, J#CORE-940, J#WEB-3239) * Fixes a regression in handling free objects in the xref table. (J#CORE-927) * Fixes an issue where `CapHeight` wasn’t added when embedding files. (J#CORE-937) ### Examples * Adds an on-device AI Assistant example (`OnDeviceAIAssistantExample.swift`). See our [on-device AI Assistant guide](https://www.nutrient.io/guides/ios/ai-assistant/on-device.md) for more information. (J#IOS-854) * Updates the Minimal example project to use SwiftUI. (#48907) * Fixes a memory leak in the AI Assistant example caused by a retain cycle with the more info button action. (#49187) ## 26.1.0 — 16 Oct 2025 See the [release notes](https://www.nutrient.io/guides/ios/releases/26-1.md) for details about our preview of on-device AI Assistant using Foundation Models. ### PSPDFKitUI * Adds respecting `PDFDocumentFeaturesSource.canExtractTextAndImages` for the Copy menu item in AI Assistant chats to disable copying. (Z#127201) * Fixes the Share menu item not being disabled when `PolicyEvent.pasteboard` was disabled. This global setting is now forwarded to `PDFDocumentFeatures.canExtractTextAndImages` for each document. (Z#127201) * Improves UI responsiveness in complex documents when pointer hover occurs over a page that is still loading. (J#IOS-774) * Improves the search bar appearance when search is active in the annotation list, outline list, and document picker. (#48924) * Fixes `PDFTabbedBar` showing buttons and tabs too close to the edge of the screen on iPhone in landscape. (#48926) * Fixes superfluous annotation change notifications being posted when executing go to actions, such as opening search results. Extra notifications might still be posted for other types of actions. (J#IOS-925) ### PSPDFKit * Removes methods to convert `NSValue` to and from `CGPoint` and `CGRect`. Implement your own helpers for these conversions instead. (#48757) * Deprecates `NSValue.valueWithDrawingPoint(_:)` in favor of `NSValue.init(drawingPoint:)`. (#48757) * Deprecates the `PolicyEvent`s `print`, `email`, and `message`, which are never checked. Use `PDFDocumentFeatures.canPrint` or `DocumentSharingConfiguration.excludedActivityTypes` instead. (Z#127201) * Improves accessibility support when working with annotations. When adding or flattening annotations in a document that already supports PDF/UA (the accessibility standard for PDFs), the SDK now preserves accessibility information by inserting the necessary tags. This helps maintain PDF/UA compliance and improves compatibility with assistive technologies in other PDF readers. (J#CORE-923) * Fixes an issue where certain Arabic fonts (for example, Noto Kufi) didn’t render text correctly. (J#WEB-3371) * Fixes a crash when attempting to repair struct tree parents in PDFs with a missing `ParentTree`. (J#CORE-919) * Fixes full text search errors when the search string contains some reserved characters. (J#CORE-922) * Fixes some outline elements being lost after editing documents with broken outline references. (J#CORE-915) * Fixes bookmarks being removed from the original page after duplicating a page in Document Editor. A bookmark won’t be added to the newly created page. (J#CORE-322) ### Instant * Fixes an issue where users were unable to delete their own replies to Instant comment threads attached to another user’s annotation. (Z#127721) ## 26.0.0 — 10 Sep 2025 This release is ready for iOS 26. Learn more in the [release notes](https://nutrient.io/guides/ios/releases/26.md). * Nutrient iOS SDK now requires and is built with Xcode 26.0. ### PSPDFKitUI * Deprecates `PDFConfiguration.halfModalStyle`, `PresentationOption.halfModalStyle`, and the `PresentationHalfModalStyle` type, which no longer have any effect. (J#IOS-878) * Adds support for presentations morphing from bar buttons with the new iOS 26 design. (J#IOS-838) * Adds a soft edge effect instead of bar background by default on iOS 26 when using `PDFNavigationController`. (J#IOS-839) * Adds a hard edge effect when using `PDFTabbedViewController` on iOS 26 and the tabbed bar is visible instead of a soft edge effect. (J#IOS-895) * Adds more items to the default menu for selected annotations to suit the morphing edit menus with the new design. (#48693) * Adds a glass effect background to `FlexibleToolbar` on iOS 26. (#48419) * Adds a glass effect background to `ScrubberBar` if `thumbnailBarMode` is `.floatingScrubberBar` on iOS 26. (#48403) * Adds the new design to the form input accessory view layout on iOS 26. (J#IOS-899) * Adds type-safe and concurrency-safe `NotificationCenter` messages: `AnnotationToolbarController.VisibilityDidChangeMessage`, `ApplePencilManager.WasDetectedMessage`, `ApplePencilManager.EnabledDidChangeMessage`, `GalleryItem.ContentStateDidChangeMessage`, `MediaPlayerController.DidFinishMessage`, `MediaPlayerController.DidPauseMessage`, `MediaPlayerController.DidStartMessage`, `NetworkActivityDidFinishMessage`, `NetworkActivityDidStartMessage`, `PDFAppearanceModeManager.DidChangeMessage`, `PDFDocumentEditorToolbarController.VisibilityDidChangeMessage`, `PDFDocumentViewController.DidCleanupSpreadViewMessage`, `PDFDocumentViewController.DidConfigureSpreadViewMessage`, `PDFDocumentViewController.DidEndDisplayingSpreadViewMessage`, `PDFDocumentViewController.SpreadIndexDidChangeMessage`, `PDFDocumentViewController.WillBeginDisplayingSpreadViewMessage`, `PDFFormInputAccessoryView.DidPressClearButtonMessage`, `PDFFormSubmissionController.DidFailLoadingMessage`, `PDFFormSubmissionController.DidFinishLoadingMessage`, `PDFFormSubmissionController.DidStartLoadingMessage`, `PDFPageView.SelectedAnnotationsDidChangeMessage`, `UsernameHelper.ViewDidDismissMessage`, `WebViewController.DidFailLoadingMessage`, `WebViewController.DidFinishLoadingMessage`, and `WebViewController.DidStartLoadingMessage`. (#48081) * Improves the appearance of the annotation inspector to more closely match default system UI in both the old and new designs. The updated appearance combines the best of the previous `card` and `system` options for `PDFConfiguration.halfModalStyle`, and therefore this configuration property is no longer used. (J#IOS-878) * Improves the appearance of the pinned search bar in modal search on iOS 26. (J#IOS-804) * Improves the layout of the Clear Field and Done buttons when a form element is selected so that Done is on the trailing side. (#48672) * Improves responsiveness when resizing the window (such as on device rotation) with complex documents when no annotations are selected. (J#IOS-774) * Changes how `Toolbar` is customized on iOS 26. The `standardAppearance` and `compactAppearance` properties no longer have any effect. Use other customization APIs, like `backgroundView` and `barTintColor` now. (J#IOS-839) * Changes `FlexibleToolbar` to use black or white instead of the `tintColor` for buttons, to match the new design on iOS 26. (#48419) * Changes menu items on iOS 26 to use a title instead of images as the horizontal bar menu can be expanded into a context menu. (#48483) * Updates the selection indication of `annotationButtonItem`, `thumbnailsButtonItem`, `documentEditorButtonItem`, and `contentEditingButtonItem` to fit better with the new design. (#48478) * Updates Done and Cancel buttons to use ✓ and × with the new design on iOS 26. (J#IOS-904) * Fixes a crash on iOS 26 when using the scrollable thumbnail bar and double page mode, and setting the document after the `PDFViewController` appears. (#48610) * Fixes possible UI freezes when showing the sharing options for complex documents. (J#IOS-774) ### PSPDFKit * Adds type-safe and concurrency-safe `NotificationCenter` messages: `BookmarkManager.DidChangeMessage`, `Document.UnderlyingFileDidChangeMessage`, `Document.WillSaveAnnotationsMessage`, `DocumentCheckpointer.DidSaveMessage`, `DownloadManager.TaskDidFailMessage`, `DownloadManager.TaskDidSucceedMessage`, `DownloadManager.TaskDidStartMessage`, `PDFLibrary.DidClearIndexesMessage`, `PDFLibrary.DidFinishIndexingDocumentMessage`, `PDFLibrary.DidRemoveDocumentMessage`, and `PDFLibrary.WillStartIndexingDocumentMessage`. (#48081) * Fixes line break characters being ignored in text markup annotation’s `markedUpString`. (J#IOS-585) ### Instant * Fixes Instant Comment markers disappearing. (J#IOS-844) ### Examples * Fixes alerts being shown in Instant Catalog examples after the connection to the server idled for over a minute. (#48600) * Fixes truncated back buttons in Catalog examples with the new iOS 26 design. (J#IOS-804) ## 14.12.0 — 20 Aug 2025 We’re introducing [release notes](https://nutrient.io/guides/ios/releases/14-12.md), which contain additional background explanation about updates to Nutrient iOS SDK. We recommend reading the notes this time to learn about our plans for iOS 26 and Xcode 26 compatibility. ### PSPDFKitUI * Deprecates `WebViewControllerAvailableActions.openInChrome` and removes it from the default actions of `WebViewController`, since it typically wouldn’t be used. Users can set their default browser to Chrome. (#48432) * Improves responsiveness when showing pages with links and other annotations in complex documents. (J#IOS-803) ### PSPDFKit * Improves discovery of widgets with broken links to their corresponding form fields. (J#CORE-885) * Improves handling of orphan page references when exporting edited documents. (J#CORE-896) * Fixes cases where safe types like `NSNumber` weren’t explicitly declared for `NSSecureCoding`, which could have resulted in warning logs. (#45149) * Fixes deadlocks that could occur when rendering documents with more than 100 pages. (J#IOS-830) * Fixes some issues that may happen when signing documents with elliptic curve keys (ECDSA). (J#CORE-901) ## 14.11.0 — 24 Jul 2025 ### PSPDFKitUI * Deprecates `Notification.Name.PSPDFFreeTextAccessoryViewDidPressClearButton`, which was never posted. Use `FreeTextAccessoryViewDelegate.clearButtonPressed(on:)` instead. (#48082) * Adds `AIAssistantView` for SwiftUI AI Assistant integration. (J#IOS-770) * Adds support for styling `AIAssistantView` in SwiftUI. Introduces the `aiAssistantStyle(_:)` modifier for applying custom styles to `AIAssistantView` using the new `AIAssistantStyle` type. Also adds `AIAssistantMessageStyle` and `AIAssistantInputStyle` for customizing message and input field styling, respectively. (J#IOS-837) * Adds support for customizing the appearance of `AIAssistantViewController`. Introduces the `aiAssistantAppearance` property on `AIAssistantViewController`, configurable via the new `AIAssistantAppearance` type. Also adds `AIAssistantMessageAppearance` and `AIAssistantInputAppearance` for customizing message and input field styling, respectively. (J#IOS-837) * Adds `setPageIndexWithHighlights(_:highlights:)` to `PDFViewController` for navigating to a portion of a particular page and highlighting it. This can be used for navigation while responding to a navigation action from AI Assistant. (J#IOS-785) * Adds the `onDocumentNavigationAction` modifier for handling document link interactions in `AIAssistantView`. (J#IOS-770) * Improves `ImagePickerController` to support form sheet presentation. (J#IOS-769) * Improves responsiveness when scrolling, zooming, tapping pages, and selecting text in complex documents with no annotations or links. (J#IOS-765) * Fixes a crash on iOS 26 that occurs when changing the page transition options while a document was visible. (J#IOS-806) * Fixes document navigation links not working in AI Assistant after a failed connection is retried successfully. (#48048) * Fixes document page views rescaling on iPads when toggling user interface visibility on iOS 26.

(J#IOS-688) * Fixes unexpected page jumps that occur when the page mode changes after a `PDFView` resize. (J#IOS-592) * Fixes an issue where very small ink signatures weren’t placed inside the signature form field used to initiate signing. (Z#124893) ### PSPDFKit * Improves font embedding behavior. Fonts will be embedded more often, resulting in a better experience when viewed in outside viewers. (J#CORE-850) * Fixes an incorrect error — “Ignoring invalid explicit mode URL” — when calling `LibraryFileSystemDataSource.didAddOrModifyDocument(at:)` with a URL with symlinks or starting with `/private`. (Z#125022) * Fixes an issue where some CA certificates weren’t recognized as such. (J#CORE-857) * Fixes an issue where the status of some long-term validation signatures may be 'invalid'. (J#CORE-858) * Fixes a crash when creating a text parser for a page if verbose logging is enabled. (J#CORE-859) * Fixes a modified annotations error in Adobe Reader after signing documents with ink and highlight annotations.

(J#IOS-756) ## 14.9.0 — 29 May 2025 This release removes APIs that were deprecated between Nutrient iOS SDK 13.2 and 13.4 (inclusive). For more information, [see the migration guide](https://www.nutrient.io/guides/ios/migration-guides/14-9-migration-guide.md). ### PSPDFKitUI * Removes the deprecated `PDFView` initializers that took an `ObservedObject`. Pass the `Document` directly as a parameter instead. (#47415) * Improves the behavior of `MarkupAnnotationMergeBehavior.ifColorMatches` to not merge text markup annotations if this would result in losing comments. (J#IOS-495) * Fixes text markup annotations having incorrect `rects` after undoing merging (with `MarkupAnnotationMergeBehavior.ifColorMatches`). (J#IOS-495) * Fixes annotation toolbar resizing when selecting a tool after device rotation or when starting to edit a free text annotation. (J#IOS-61) * Fixes an issue where navigation bar button items configured with `leadingItemGroups` and `trailingItemGroups` weren’t displayed. (J#IOS-38) ### PSPDFKit * Removes the deprecated `PageSize` initializer `init(_:name:)`. Use `init(size:name:)` instead. (#47415) * Removes the deprecated `TextSearch` property `compareOptions`. Use `comparisonOptions` instead. (#47415) * Fixes an issue where certain form field flags weren’t considered correctly. (J#CORE-838) * Fixes an issue where form fields weren’t formatted correctly at all times. (J#CORE-676) * Fixes an issue where the primary language of the document wasn’t preserved when using the document editor. (J#CORE-840) ### Examples * Adds a Catalog example showing adding annotations from a menu so the toolbar is only for drawing. (#46515) * Adds a Catalog example showing replacing the annotation toolbar with Apple’s tool picker from PencilKit. (#46515) ## 14.8.0 — 30 Apr 2025 * Nutrient iOS SDK now requires and is built with Xcode 16.3. ### PSPDFKitUI * Adds the `PDFView` modifier `menuForCreatingAnnotation` to customize the menu shown when long pressing an empty part of a page. (J#IOS-719) * Fixes memory leaks with `PDFView` when used with a scope and the document changes after creation. (J#IOS-752) * Fixes the Select More menu item being included in the menu for selected annotations, even when `editableAnnotationTypes` doesn’t contain `selectionTool`. (#47224) ### PSPDFKit * Adds support for preserving PDF/UA tags when using Document Editor. (J#CORE-750) * Adds support for the Acrobat JavaScript API `AFTime_KeystrokeEx`. (J#CORE-639) * Adds support for the PDF JavaScript ‘global’ object. (J#CORE-801) * Improves appearance stream rendering in single-line callout and free text annotations to better fit the bounding box. (J#CORE-819) * Improves the responsiveness of starting Content Editor on pages with complex vector graphics like building plans. (#47157) * Changes the `GoToAction` to set the destination to the page reference instead of the page index. This means the `GoToAction` follows the page even if pages are moved or deleted. (J#CORE-813) * Fixes Document Editor incorrectly allowing saving in place when a custom annotation provider was used in addition to the default file annotation provider. Document Editor only supports saving in place when all annotations are in the PDF. (Z#123923) * Fixes a regression where certain OCR-processed PDFs could no longer be read correctly. (J#CORE-825) * Fixes an issue where TIFF files that switched between page sizes were rendered incorrectly.

(J#CORE-801) * Fixes text not being marked as fitting when using `generateInstantJSON(version:)` with a free text annotation. Before, the fitting attribute was only included when using the API without the version parameter. (Z#123441) * Fixes text not being marked as fitting when exporting XFDF for a free text annotation. (Z#123441) ### Instant * Adds AI Assistant for Instant-managed documents. This can be used to summarize, translate, and ask questions about documents. This feature requires you to run Nutrient AI Assistant on your server. Once that’s set up, provide your `AIAssistantConfiguration` and add `AIAssistantButton` or `aiAssistantButtonItem` to your toolbar. If you’d like to try this, refer to our [AI Assistant guides](https://www.nutrient.io/guides/ios/ai-assistant.md). (J#IOS-750) ### Examples * Adds a Catalog example showing importing annotations from XFDF. (#47153) ## 14.7.0 — 2 Apr 2025 ### PSPDFKitUI * Improves scrolling performance on Mac when the pointer is over a page with lots of text.

(#46977) ### Examples * Adds a Catalog example showing how to remove the Writing Tools menu item. (Z#122763) ## 14.6.0 — 6 Mar 2025 This will be our last release published to the CocoaPods specs repository (aka trunk) in preparation for [this service becoming read-only](https://blog.cocoapods.org/CocoaPods-Specs-Repo/). Our documentation has always shown adding our `pod` using an explicit `podspec` URL rather than from trunk, and this setup will continue to work. If you modified your Podfile to specify only `pod 'PSPDFKit'`, then change this to `pod 'PSPDFKit', podspec: 'https://my.nutrient.io/pspdfkit-ios/latest.podspec'`. We recommend [migrating from CocoaPods to Swift Package Manager](https://www.nutrient.io/guides/ios/knowledge-base/how-do-i-migrate-from-cocoapods-to-spm.md), which is more modern and actively maintained. (J#IOS-672) ### PSPDFKitUI * Adds AI Assistant, which can be used to summarize, translate, and ask questions about documents. This feature requires you to run Nutrient AI Assistant on your server. Once that’s set up, provide your `AIAssistantConfiguration` and add `AIAssistantButton` or `aiAssistantButtonItem` to your toolbar. If you’d like to try this, refer to our [AI Assistant guides](https://www.nutrient.io/guides/ios/ai-assistant.md). (J#IOS-611) * Adds a `SearchViewController.highlightColor` property to customize the search results list. See the new `ModalSearchHighlightColorExample`. (Z#121707) * Adds support for sending emails from links in documents on Mac or when a default email app other than Apple Mail is set up. (Z#121722) * Changes the default behavior for opening email links from using Apple Mail (`MFMailComposeViewController`) to opening the `mailto` link directly, which opens the user’s chosen default email app. To revert this, change the new `emailSendingBehavior` configuration property to `.preferAppleMail`. (Z#121722) * Fixes sharing a temporary rotated image document producing an incorrect output image. (J#IOS-703) * Fixes some scenarios where autosave wouldn’t trigger when using multiple windows on iPad and closing or switching between those windows. (Z#122069) * Deprecates `SearchViewController.numberOfPreviewTextLines`, which was unused. (Z#121707) ### PSPDFKit * Improves memory usage when decoding large page streams, allowing better out of memory handling. (J#CORE-253) * Fixes a crash that occurred when trying to digitally sign a signature form field whose `name` and `fullyQualifiedName` are different. (#46414) * Fixes a crash with document comparison when aligning documents using points on a straight line. This will now report the error code `.comparisonProcessorInvalidPoints`. (J#CORE-758) * Fixes an issue where some annotations weren't drawn correctly on pages with transparency. (J#CORE-783) * Fixes an issue with opening certain PDFs that have a broken encryption descriptor. (J#CORE-776) * Fixes text in free text callout annotations not remaining fitting when added using Instant JSON or XFDF from Nutrient SDK on another platform or a device with different fonts. (Z#120290) ## 14.5.0 — 29 Jan 2025 ### PSPDFKitUI * Adds `@MainActor` to `SignatureCreationViewControllerDelegate`, `DocumentAlignmentViewControllerDelegate`, and `AnnotationSetStore` to improve support for Swift concurrency checks. (J#IOS-483) * Fixes a crash when presenting the time picker for form fields on Mac Catalyst. (Z#120814) * Fixes an issue where date or time pickers might not have changed the value of a form field if the JavaScript formatting function was used incorrectly. Now the detection is more robust, and if the correct format can't be found, it falls back to keyboard entry. (Z#120814) * Fixes an issue when using Content Editor with type3 fonts where some text boxes appeared far too small. (J#CORE-754) ### PSPDFKit * Improves handling of specific broken PDF forms, where multiple instances of the same form are combined into a single PDF. (J#CORE-646) * Updates the Botan library to version 3.6.1. (J#CORE-683) * Fixes some Chinese characters not rendering on iOS 18. When a document doesn’t contain embedded fonts for any characters that need rendering, Nutrient uses fonts from the system as a fallback. However, in iOS 18, Apple removed compatible versions of its fonts for Chinese characters. To resolve all the cases of missing characters we’ve seen so far, we’re now including a font in our framework that can render Simplified Chinese characters. This comes at the cost of a 10 MB increase in framework size. We’ll continue to look for alternative solutions to mitigate this size increase. If you still encounter problems with characters missing in any documents, [contact us](https://www.nutrient.io/support/request). (J#IOS-697) * Fixes logging showing some messages similar to `` instead of the correct message due to a system issue in `os.log`. (J#IOS-673) * Fixes an issue where the document IDs of some documents may be incorrectly truncated. (J#AI-123) * Fixes slowdown when decoding certain TIFF images. (J#CORE-757) * Fixes an issue with TIFF images with 0 DPI. (J#CORE-770) ## 14.4.0 — 15 Jan 2025 Nutrient iOS SDK now requires and is built with Xcode 16.2. ### PSPDFKitUI * Adds Done and Clear Field buttons above the date or time picker for form fields. (J#IOS-662) * Adds selecting the current date and time automatically when selecting an empty form field with date or time formatting. (J#IOS-671) * Adds undo for changes to form fields with the date or time picker. (J#IOS-671) * Adds haptic feedback from Apple Pencil Pro and the trackpad on Magic Keyboard for iPad Pro (M4) when snapping to aspect ratio guides while resizing annotations using the resize handles. (#44979) * Improves the consistency of how many characters are allowed in multi-line, non-scrolling text field form elements. (J#IOS-568) * Changes the title ‘Embedded Files’ to ‘Attachments’ to sound less technical. (#46096) * Fixes an issue where `onDidTapOnAnnotation(perform:)` was not called when `PDFView` was contained in a `TabView` using `.tabViewStyle(.page)`. (Z#120630) * Fixes page content being cut off in vertical continuous scrolling when the keyboard was visible while scrolling to a new page. (J#IOS-659) * Fixes secondary click between selected characters sometimes dismissing selected text instead of showing text selection menu. (J#IOS-620) * Fixes the keyboard shortcut for `BrightnessButton` to use CMD+B to match `brightnessButtonItem`. (#46010) * Fixes the vertical scroll indicator not being visible in scrollable text form elements. (J#IOS-568) * Fixes various memory leaks related to the signature creation UI. (#46056) * Fixes warning logs about not finding `UITextInteraction` recognizers on Mac Catalyst. (#45981) * Fixes a content editing issue where moving a piece of text with a subsetted font could cause a character swap in some viewers. (J#CORE-577) ### PSPDFKit * Adds support for loading larger image documents. (Over 20 times larger on devices with 8 GB of memory.) There is still a limit based on the device memory and bits per pixel. (J#IOS-400) * Fixes an issue where conversion was not possible with evaluation license. (J#WEB-2219) * Fixes an issue where in certain PDFs the outline/bookmarks wasn't preserved when using the Document Editor. (J#CORE-753, J#CORE-707) * Fixes an issue with GoTo Remote and Goto Embedded actions. (J#CORE-751) * Fixes a crash when opening a PDF with malformed forms. (J#CORE-745) * Fixes crash when dealing with malformed attachments. (J#CORE-728) ## 14.3.0 — 5 Dec 2024 ### PSPDFKitUI * Deprecates `UIAction.Identifier.PSPDFKit.paste` in favor of `UIAction.Identifier.paste`, which is identical. (#45634) * Adds showing a date or time picker for form fields that use date or time formatting. (J#IOS-618) * Adds a `signingAreaAspectRatio` property to `SignatureCreationViewController.Configuration` to customize the shape of the signing area. (#45860) * Adds a border to indicate when read-only annotations are selected. (Z#119400) * Improves the selection state of the thumbnail bar (both scrubber and scrollable) to more consistently match the visible spread in most common configurations. In more unusual configurations where many spreads are visible at once, tapping pages in the thumbnail bar will still result in the highlighted page being offset from the tapped page. (J#IOS-591) * Fixes quickly double tapping to start editing free text annotations not working. (J#IOS-607) * Fixes quickly double tapping to start moving annotations not working. (J#IOS-606) * Fixes a memory leak when dismissing `PDFView`. (J#IOS-667) * Fixes the view state being lost (resetting to the top of the document) when changing the configuration used by `PDFView` or setting the `configuration` property of `PDFViewController`. (#45835) ### PSPDFKit * Updates the default watermark on visible digital signatures. (J#HG-1468) * Fixes an issue retrieving the text of a highlight annotation on rotated pages. (J#CORE-449) * Fixes an issue where PDFs with a large number of unique fonts used a lot of memory, especially during indexing. (J#CORE-748) * Fixes an issue where callout annotations weren’t rendered correctly in other PDF readers. (J#ANDR-937) * Fixes lockup or crash issues when opening certain malformed PDF forms. (J#CORE-726) ## 14.2.1 — 2 Dec 2024 ### PSPDFKitUI * Adds a border to indicate when locked line annotations are selected. (Z#119400) ### PSPDFKit * Fixes an issue where certain license keys couldn’t be read correctly. (J#CORE-725) ## 14.2.0 — 12 Nov 2024 With our [new company name](https://www.nutrient.io/blog/welcome-to-nutrient/), PSPDFKit for iOS is now called Nutrient iOS SDK. No technical details have changed: Our modules are still called `PSPDFKit` and `PSPDFKitUI` and are available at the same [Swift package URL](https://github.com/PSPDFKit/PSPDFKit-SP/). We want to make this a smooth transition. Nutrient iOS SDK now requires and is built with Xcode 16.1. This release removes support for iOS 15 and macOS 12. Your deployment target must now be set to iOS 16 and macOS 13 or greater. (J#IOS-532) This release also removes APIs that were deprecated between Nutrient iOS SDK 12.0 and 13.0 (inclusive). This includes the legacy menu customization APIs that used Apple’s deprecated `UIMenuController` and `UIMenuItem` APIs. For more information, [see the migration guide](https://www.nutrient.io/guides/ios/migration-guides/14-2-migration-guide.md). (J#IOS-529) ### PSPDFKitUI System text selection is now used on document pages. This was a large internal change that has provided improved system integration and a native look and feel. As a result of this, some customization APIs have changed. * Deprecates the `selectText` and `deselectText` components of `DocumentViewInteractions`. With the switch to system text selection, these components are now only used for image selection. We’d like to bring back similar APIs for system text selection, but to do that, it would help us a lot if you [let us know](https://www.nutrient.io/support/request) how you’re using these APIs. (J#IOS-570) * Deprecates `SpeechController`, which is no longer used with the switch to system text selection. (J#IOS-180) * Deprecates `TextSelectionView.selectionHitTestExtension`, as it provided limited functionality and worked only in certain conditions. Reach out to us on Support if you need assistance with customizing when to begin text selection. (J#IOS-572) * Deprecates `UIAction.Identifier.PSPDFKit.define` and `UIAction.Identifier.PSPDFKit.searchWeb` in favor of `UIMenu.Identifier.lookup`. (J#IOS-180) * Deprecates `UIMenu.Identifier.PSPDFKit.accessibility` in favor of `UIMenu.Identifier.speech`. (J#IOS-180) * Deprecates the `TextSelectionMode` enum, which is no longer used. (J#IOS-382) * Deprecates `PDFPageView.select(glyphs:presentMenu:animated:)` in favor of the new method `select(glyphs:animated:)` because the `presentMenu` parameter is now ignored. (J#IOS-180) * Deprecates `PSPDFGalleryOptionCover`, which has long been informally deprecated in favor of `GalleryItem.Option.coverImage` and `GalleryItem.Option.coverMode`. (Z#119024) * Adds the standard Look Up, Translate, and Writing Tools menu items for selected text. Look Up replaces Define. (J#IOS-180) * Improves the look and feel of text selection to match system behavior. (J#IOS-180) * Improves language detection in the Speak menu item for selected text by using the system implementation, which asks the user in the case of ambiguity. (J#IOS-180) * Improves the consistency of how many characters are allowed in single-line, non-scrolling, auto-sized text field form elements. (J#IOS-461) ### PSPDFKit * Deprecates `URLAction.offset`, `Action.Option.offsetKey`, `Action.Option.coverKey`, and `Action.Option.pageKey`, which all haven’t had an effect for some time. (Z#119024) * Adds support for reading the widget tab order. (J#CORE-660) * Improves text extraction by replacing invalid characters with the Unicode Replacement Character (0xFFFD). (J#CORE-701) * Updates the format of version returned in `SDK.versionString`. It now returns the version information in a new format: "Nutrient iOS SDK {version-number} ({build-number})". For example: Nutrient iOS SDK 14.2.0 (1420). (J#IOS-594) * Updates the HarfBuzz library to version 10.0.1. (J#CORE-693) * Fixes a crash that may happen when saving LTV information in a document. (J#CORE-710) * Fixes an issue where handwritten signatures may appear unexpectedly cropped. (J#CORE-713) * Fixes an issue where the signature validation status after certificate revocation checks may be invalid if the document has multiple digital signatures. (J#AND-842) * Fixes an issue where the tab index of signature fields wasn't calculated correctly. (J#CORE-660) * Fixes issues with Type 3 fonts and text extraction. (J#CORE-703) ### Examples * Adds a ‘Custom Speak Menu Item’ example in Catalog, which shows how to replace the system Speak menu item to change the speech rate, pitch, or language. (#45588) ## 14.1.1 — 21 Oct 2024 ### PSPDFKit * Fixes a deadlock that could occur when generating Instant JSON in response to an annotation change notification. (J#IOS-584) * Fixes an issue where too much memory was used when decoding JPEG2000 image masks. (J#CORE-636) ## 14.1.0 — 10 Oct 2024 ### PSPDFKit * Adds shrinking the measurement label to fit inside elliptical and rectangular area measurement annotations instead of showing the note indicator. (J#IOS-562) * Fixes a regression from PSPDFKit 13.6, where applying Instant JSON to a document didn’t work without the forms feature in the PSPDFKit license. (J#IOS-575) * Fixes the blend mode not being read correctly, resulting in annotations reverting to a normal blend mode. (J#CORE-691) * Fixes PDFs with millions of outline elements using too much memory. (J#CORE-694) * Fixes form contents sometimes being rotated after exporting and then importing from Instant JSON. (J#CORE-647) * Fixes form flags being overwritten when using the processor and when `NeedAppearances` was set in the PDF. (J#CORE-45331) * Fixes handwritten signatures sometimes appearing distorted in some page orientations. (J#ANDR-824) * Fixes an incorrect font weight being selected for the Lexend font. (J#CORE-339) ### Examples * Adds the calibration tool to the Measurement Tools example in our Catalog app. (J#IOS-562) ## 14.0.1 — 19 Sep 2024 ### PSPDFKit * Fixes some annotations losing their font color when exported to XFDF and imported again. (J#CORE-680) * Fixes undo not tracking the correct annotations when using a document with multiple data providers. (Z#117081) * Fixes PDF JavaScript reporting an error when setting a custom value to a combo box form field. (J#CORE-675) * Fixes parsing timestamp policies with short OIDs in digital signatures. (J#SERVER-1231) * Fixes digitally signing a document sometimes resulting in an error in Adobe Acrobat about a modified page. (J#CORE-45204) * Fixes digitally signing with the SHA384 hashing algorithm not working. (Z#116874) ## 14.0.0 — 16 Sep 2024 PSPDFKit now requires and is built with Xcode 16.0. This release adds support for iOS 18, macOS 15 Sequoia, and visionOS 2, while still working back to iOS 15 and macOS 12 Monterey. To concentrate our development and support efforts, we'll soon raise our deployment targets to iOS 16 and macOS 13 Ventura, removing support for iOS 15 and macOS 12 Monterey. ### PSPDFKitUI * Deprecates `PDFConfiguration.textSelectionShouldSnapToWord`. PSPDFKit will soon switch to standard system text selection and will no longer support forced snapping. (J#IOS-382) * Improves performance when entering custom text in choice form fields by not updating the document render until after text editing finishes. (Z#109083) * Changes the keyboard type for ‘Go to Page’ to `.numbersAndPunctuation` to enable non-numeric input on iPhone. (#45008) * Fixes an issue where the numerical value of `NSNotFound` is displayed in the outline list when the page index can't be determined for an outline element. (Z#116497) ### PSPDFKit * Changes the return value of `Document.pageLabelForPage(at:substituteWithPlainLabel:)` to `nil` when `NSNotFound` is provided for the `pageIndex` parameter. (Z#116497) * Fixes a crash when opening certain image files with broken XMP/EXIF headers. (J#CORE-665) * Fixes an issue where annotations exported to XFDF and then imported again may lose their text color. (J#CORE-648) * Fixes an issue where annotations loaded using `XFDFAnnotationProvider` may not be visible right away until you select them. (J#CORE-669) * Fixes an issue where signatures on rotated pages were displayed incorrectly. (J#CORE-672) * Fixes an issue where some signatures with Long-Term Validation information may be incorrectly reported as invalid. (J#CORE-654) * Fixes an issue where the same font was embedded multiple times when entering diacritics, leading to a massive file size. (J#CORE-634) * Removes the curved edges on text highlights. (J#ANDR-313) ## 13.9.1 — 30 Aug 2024 * Improves the evaluation experience. (J#CORE-667) ## 13.9.0 — 15 Aug 2024 ### PSPDFKitUI * Deprecates `PDFConfiguration.textSelectionMode`. We recommend leaving this at its default value of `automatic` to provide the best user experience. PSPDFKit will switch to standard system text selection soon and will no longer support alternative modes. (J#IOS-382) * Adds automatically setting the background for tab bars with `PDFView`. (Z#115586) * Changes `PDFView`’s navigation bar toolbar background from `.regularMaterial` to the default, which is less transparent, providing better legibility. (Z#115586) * Improves performance when first creating a `PDFConfiguration` object. (Z#115578) * Fixes default instances of `PDFConfiguration` not being equal, which could have caused infinite update loops with `PDFView`. (J#IOS-450) * Fixes dragging selected annotations not working consistently while the selection tool is active. (J#IOS-409) * Fixes the scrubber bar not being displayed in vertical configurations on Mac Catalyst. (J#IOS-415) * Fixes the close button not being added by default when `PDFViewController` is presented modally directly in a navigation controller and the `useParentNavigationBar` configuration property is `true`. (#41850) ### PSPDFKit * Updates HarfBuzz library to 9.0.0. (J#CORE-625) * Fixes an issue where a PDF rendered incorrectly. (J#CORE-643) * Fixes an issue where converting a bitonal TIFF with a lot of pages consumed too much memory. (J#CORE-621) * Fixes an issue where setting a choice form element's contents could lead to a deadlock. (J#IOS-344) ### Examples * Improves the E-Reader example and various SwiftUI examples in the Catalog app on iPad in landscape by using `.adaptive` spread fitting instead of `.fill`. (#44770) * Renames the “Highlighting like in Apple Books” Catalog example to “Create Highlights From Selected Text” because the behavior of Apple Books has changed. (J#IOS-382) ## 13.8.0 — 16 Jul 2024 PSPDFKit now requires and is built with Xcode 15.4. ### PSPDFKitUI * Adds support for managing toolbar button setup while using `PDFView` in SwiftUI. You can now add buttons like `DefaultToolbarButtons`, `AnnotationButton`, `SearchButton`, `OutlineButton`, and `ThumbnailsButton` using the `toolbar(content:)` modifier to customize the toolbar. See [our SwiftUI guide](https://www.nutrient.io/guides/ios/getting-started/swiftui.md#navigation-bar-setup) for more information. (J#IOS-401) * Adds `PDFView.showDocumentTitle(_:)` to control where the document title is shown. Also changes the default to not show the document label when using `PDFView`.

See the [Introducing PSPDFKit for visionOS](https://www.nutrient.io/blog/pspdfkit-for-visionos/) blog post for details. ⚠️ The XCFrameworks in this release no longer have valid signatures. Please update to 13.3.1 or see our [framework signature validation failed](https://www.nutrient.io/guides/ios/troubleshooting/getting-started/framework-signature-validation-failed.md) guide. PSPDFKit now requires and is built with Xcode 15.2. * Adds privacy manifests for all our frameworks. (J#IOS-26) * Removes APIs that were deprecated in PSPDFKit 11.4 and 11.5. For more information see the [migration guide](https://www.nutrient.io/guides/ios/migration-guides/pspdfkit-13-3-migration-guide.md). (#42617) ### PSPDFKitUI * API: Calling `WebViewController.modalWebView(with:)` on a subclass of `WebViewController` no longer attempts to create an instance of the subclass. (Z#39981) * API: Changes timestamps from `DrawView.timePoints` to be relative to the first touch (so they start at zero) instead of using Unix timestamps. This was done to avoid use of `ProcessInfo.systemUptime` which is a “required reason” API. (J#IOS-26) * Adds `dashArray`, `lineEnd1`, `lineEnd2`, and `fillColor` (line end color) to the default `propertiesForAnnotations` for measurement annotations, which makes these properties editable in the annotation inspector. (Z#107080) * Adds `PDFConfiguration.mainToolbarMode` on visionOS that can be used to display toolbar items such as annotation tool, document editing, etc. in the navigation bar or in an ornament anchored to the top of the main window. See [our guide](https://www.nutrient.io/guides/ios/user-interface/main-toolbar-visionos.md) for more details. (#43078) * Adds `PDFViewController.setMainToolbarOrnamentItems(_:for:)` to configure the toolbar items in the ornament anchored to the top of the main window. This can use the new in-built ornament items such as `PDFViewController.annotationOrnamentItem`, `bookmarkOrnamentItem`. See [our guide](https://www.nutrient.io/guides/ios/user-interface/main-toolbar-visionos.md) for more details. (#43080) * Adds annotation and document editor toolbars as ornaments on visionOS. (J#IOS-134) * Adds hover feedback for visionOS throughout the UI, including in the thumbnail view mode, scrubber bar, and various toolbars. (J#IOS-119, J#IOS-120, J#IOS-121, J#IOS-122) * Adds tabs to main toolbar ornament when using `PDFTabbedViewController` on visionOS. (J#IOS-149) * Improves adding Electronic Signatures from the annotation creation menu (long press in empty space on page) by adding the signature annotations at the point that was pressed instead of in the middle of the page. (J#IOS-214) * Optimizes annotation and text selection menus for visionOS. (#42658) * Fixes a crash when showing the link annotation editor for a subclass of `Document`.

(J#IOS-254) * Fixes the font selection list unexpectedly closing when adding a signature with the device in landscape orientation. (J#IOS-65) ### PSPDFKit * API: Changes the signature of the `unlockCertificateChain(withPassword:) async` API to be synchronous as it does not carry out any tasks asynchronously. (#42978) * API: Removes `.widthInsensitive` from the default value of `TextSearch.compareOptions` because this option is not compatible with smart search, which is enabled by default. This will have no effect on behavior unless you’re disabling smart search by removing `.regularExpression` from this option set. (J#IOS-193) * API: The implementations of `NSCopying` in `Document`, `TextSearch`, and `PageLabelFormatter` will no longer return instances of subclasses. This was unsafe because subclasses may have additional initialization requirements. (Z#39981) * API: `PDFViewController.present(with:options:sender:animated:configurationBlock:)` will no longer present an instance of a subclass of `PDFViewController`. If you need to use your subclass, override this method. (Z#39981) * Deprecates `PageSize(_:name:)` in favor of the existing equivalent initializer `PageSize(size:name:)`. (Z#39981) * Deprecates `TextSearch.compareOptions` in favor of the new `TextSearch.comparisonOptions`. The old property will no longer store unhandled options from `NSString.CompareOptions` such as `.anchored` because it is internally backed by the new property. (J#IOS-193) * Adds API for programmatic regular expression (regex) search in a document by using the new `TextSearch.comparisonOptions` property with `TextSearch.ComparisonOptions.regularExpression`. (J#IOS-193) * Adds support for adding long term validation when signing a form element using `Document.sign(formElement:configuration:outputDataProvider:)`. (J#IOS-216) * Adds support for adding long term validation when validating a signed form element using `Document.addLongTermValidation(toFormElement:certificates:)`. (J#IOS-217) * Adds support for verifying a signature and checking the revocation status of the used certificates using `PDFSignatureValidator.verifySignatureAndCheckRevocationStatus(withTrustedCertificates:)`. (J#IOS-229) * Improves Document Editor performance when dealing with large documents. (#42927) * When initializing a `Document` with data providers or appending data providers to an existing document, there is now an assertion that all data providers need to be unique. (Z#107544) * Fixes a potential crash when generating AP streams. (J#CORE-364) * Fixes a regression from PSPDFKit 13.2 where deadlocks would occur more frequently with immediate document checkpointing. The issue remains, but the frequency should be back to how it was before. (J#IOS-185) * Fixes freetext callout rendering and rich text link render on rotated pages. (J#CORE-297) * Fixes vertical alignment of free text annotations when using rich text. (#42793) ### Examples * Adds `DigitalSignatureConfigurationExample` that allows customizing various options when digitally signing. (#42823) * Fixes drawn signatures being very thin in the Sign All Pages Catalog example. (J#IOS-214) ## 13.2.0 — 20 Dec 2023 _See the [announcement post](https://www.nutrient.io/blog/pspdfkit-13-2-ios-advanced-digital-signatures/)._ ⚠️ The XCFrameworks in this release no longer have valid signatures. Please update to 13.3.1 or see our [framework signature validation failed](https://www.nutrient.io/guides/ios/troubleshooting/getting-started/framework-signature-validation-failed.md) guide. * Improves API safety for apps using Objective-C by removing various uses of `__kindof` (which allows implicit casting to subclasses). (#42436) ### PSPDFKitUI * Improves contrast of text in the bookmark list in dark mode. (#42655) * Fixes free text annotations arriving via Instant, Instant JSON or XFDF that fitted without clipping on another device sometimes clipping when moved. (J#IOS-190) ### PSPDFKit * API: Improves type safety by changing the return type of `Document.annotations(byDetectingLinkTypes:forPagesAt:options:progress)` from `[NSNumber : [Annotation]]` to `[NSNumber : [LinkAnnotation]]`. (#42436) * Adds new digital signature API with support for timestamping via `Document.sign(formElement:configuration:outputDataProvider:)`. (J#IOS-195) * Adds additional APIs for digital signature verification on `PDFSignatureStatus`. (J#IOS-210) * Adds a new async API to unlock a PKCS12 archive - `PKCS12.unlockCertficateChain(withPassword:)`. (J#IOS-220) * Adds a `defaultMeasurementValueConfiguration` property on `Document` to set the default units and precision for the Add Scale and Calibrate Length views. (Z#39656) * Fixes a crash while looking up character codes. (J#CORE-348) * Fixes an issue where loading link annotations may incorrectly log an error. (J#CORE-281) * Fixes an issue where the cross-reference table may be invalid after saving a file. (J#CORE-321) * Fixes an issue where the wrong rich text was rendered. (J#CORE-315) * Fixes edits made to annotations after they were created being discarded when editing form fields. (J#IOS-135) * Fixes free text annotation callout line ends when importing from XFDF. (J#CORE-297) ### Examples * Adds a new example, `FormCustomDigitalSigningExample`, to illustrate carrying out a custom signing implementation using the new signing API `Document.sign(formElement:configuration:outputDataProvider:)`. (J#IOS-220) * Updates `FormDigitalSigningExampleCustomAppearanceExample` and `AsynchronousExternalDigitalSignatureExample` to use the new signing API `Document.sign(formElement:configuration:outputDataProvider:)`. (J#IOS-220) * Updates `FormDigitalSigningExample` to illustrate adding timestamp from a timestamp server using the new signing API `Document.sign(formElement:configuration:outputDataProvider:)`. (J#IOS-220) ## 13.1.0 — 2 Nov 2023 ⚠️ The XCFrameworks in this release no longer have valid signatures. Please update to 13.3.1 or see our [framework signature validation failed](https://www.nutrient.io/guides/ios/troubleshooting/getting-started/framework-signature-validation-failed.md) guide. * Adds code signatures to the distributed XCFrameworks so it’s possible to validate that they haven’t been modified since we built them. (J#iOS-23) ### PSPDFKitUI * Adds UI to scroll to a specific page by typing when tapping the page label. (J#IOS-124) * Fixes `ThumbnailBar` unnecessarily asserting that its collection view layout isn’t changed. (Z#39285) * Fixes a crash related to copying pages from an imported document in the document editor. (J#IOS-99) * Fixes a possible crash on iOS 17 when showing the quality picker when adding images.

(#39972) * Fixes some issues where errors signing documents may not be reported correctly. (#40998) * Fixes wrong data being returned when the following steps occur: add an annotation to a document, then set the annotation’s `appearanceStreamGenerator` (and set `isDirty` to `true`), then call `writeBinaryInstantJSONAttachment`. As a result of this, PSPDFKit may be stricter about a stamp with an image needing a non-empty bounding box in order to get the image as an Instant JSON attachment. (#41349) ### Instant * Fixes fetching of image annotation assets upon initial opening of an Instant document. (J#CORE-12) ### Examples * Updates some examples to not use configuration options when using a gallery URL in link annotations.

(#31815) ## 11.1.0 — 26 Oct 2021 This release adds support for Mac Catalyst apps built for macOS 12 Monterey. See the [announcement post](https://www.nutrient.io/blog/pspdfkit-11-1-ios-document-comparison). PSPDFKit now requires and is built with Xcode 13.1. This release updates the [Document Comparison](https://www.nutrient.io/guides/ios/compare-documents.md) component with a new document alignment feature. If you'd like to add this component to your license, please [contact our sales team](https://www.nutrient.io/support/request) to receive a quote. ### PSPDFKitUI * Adds `DocumentAlignmentViewController` that can be used to align two versions of a document and generate a comparison between them. (#30106) * Adds the ability to create text markup annotations in the middle of words when using trackpad or mouse. (#30990) * Fixes an issue where certain colors picked using the system color picker could appear incorrectly. (#30101) * Fixes an issue where the image source picker popover for a form element would be misplaced after rotating the device. (#29036) * Fixes an issue where the note annotation popover would shrink too much when the software keyboard was visible. (#31074) ### PSPDFKit * Adds `ComparisonProcessor` that can be used to generate a comparison between two versions of a document. (#30106) * Adds support for searching form field contents when the option to search annotation contents is enabled. (#26502) * Removes `PSPDFVersion.h`, which included the `PSPDFVersionDummy` class and preprocessor definitions for the current and previous PSPDFKit versions. We don’t anticipate any need for this file, but if you have one, please [contact us](https://www.nutrient.io/support/request). (#31315) * Updates the FreeType library to version 2.11.0. (#30900) * Updates the libjpeg-turbo library to version 2.2.1. (#30900) * Updates the HarfBuzz library to version 3.0.0. (#31113) * Updates the HarfBuzz library to version 2.9.1. (#30624) * Fixes elevated memory consumption when PDF objects need compressing. (#31317) * Fixes elevated memory consumption when encoding JPEG images. (#31205) * Fixes an issue due to a system regression in iOS 15 where calling `ProcessInfo.processInfo.isLowPowerModeEnabled` in response to a `NSProcessInfoPowerStateDidChange` notification could result in a deadlock. (#31180) * Fixes a very occasional crash when parsing stamp annotations that contained images references to invalid indirect objects. (#31093) * Fixes an issue where setting `event.value` inside a validation script may not work as expected. (#31286) * Fixes a possible undefined behavior when validating digital signature data. (#31179) * Fixes an assertion that would occur when the `rotation` property was removed from an annotation. (#31173) ### Instant * Fixes an issue where calling `copy()` on an Instant-backed `PDFDocument` would raise an exception. (#31267) * Fixes an issue where the objects returned by `InstantClient` from `localDocumentDescriptors()` would not be updated properly. (#31367, Z#27576) ### Examples * Updates `ComparisonExample` to showcase the new document comparison and alignment features. (#30106) * Updates the Minimal example to use `UIScene`-based app lifecycle. (#30767) ## 11.0.0 — 20 Sep 2021 This release adds support for iOS 15. See the [announcement post](https://www.nutrient.io/blog/pspdfkit-11-for-ios-15/). PSPDFKit now requires and is built with Xcode 13.0. ### PSPDFKitUI * Adds a `colors` property to `SignatureViewController.Configuration` to customize the available signature colors the user can pick from. (#29361) * Adds localized names for all recorded undoable commands. (#29454) * Adds support for transparent bar background changes on iOS 15 when `PDFViewController` is a direct child of a `UINavigationController` or a `UITabBarController`. For other view controller hierarchies, you should set your bar’s `scrollEdgeAppearance` to be the same as its `standardAppearance`. (#30749) * Adds an `accessibilityIdentifier` to all accessibility elements representing a `FormElement`. The `accessibilityIdentifier` matches the `fullyQualifiedName` of the corresponding form element — note that this will differ from the FQN of a form field to disambiguate the unique widgets of radio buttons, checkboxes, etc. (Z#27002) * Removes the ⌘ ← key command to navigate back in `PDFNavigationController` when running on iOS 15+ because UIKit added its own ⌘ `[` key command for this. (#30174) * `PDFNavigationController` no longer sets a `scrollEdgeAppearance`, which means that the navigation bar has no background when scrolled to the top to match modern iOS design. (#30749) * `PDFViewController` doesn’t try to become first responder when reloading on iOS 15+ since this is no longer necessary and can interfere with the UIKit focus system. (#30923) * `MultiDocumentViewController` (the superclass of `PDFTabbedViewController`) can no longer become first responder because its child `PDFViewController` is a better candidate for first responder. (#30923) * Updates `UIKeyCommand`s provided by PSPDFKit to account for system changes in iOS 15. (#30174) * Fixes an issue where a page label in the document editor was not updated during drag and drop reordering. (#30752) * Fixes the `UIViewController` method `addKeyCommands(_:)` not working on `PDFViewController` and `PDFTabbedViewController`. (#30552) * Fixes `PDFNavigationController` potentially asserting about an invalid interface orientation when presented without any child view controllers. (#30424) * Fixes an issue where free text annotations were sometimes being clipped due to incorrect bounding box calculations. (#30649) * Fixes an issue where the user interface view would not become visible after editing an empty free text annotation or when using Scribble. (#30998) ### PSPDFKit * Deprecates the `PSPDFKit.FileManager` methods `fileHandleForWriting(to:withBlock:)` and `fileHandle(forUpdating:withBlock:)` because these are not called by PSPDFKit. (#229939) * Adds support for blend mode in all annotations when using Instant JSON. If `blendMode` is not specified, it defaults to `normal`. (#29582) * Improves rendering non-Latin text (like Arabic) when selecting specific fonts. (#30517) * Updates the HarfBuzz library to 2.8.2. (#30164) * Fixes various completion handler closures not being called in some cases. (#29846) * Fixes `overlappingSignatureAnnotation` sometimes not returning the correct result in annotations that are backed by an XFDF file or other types of custom annotation providers. (#28818) * Fixes an issue where a digital signature may incorrectly report a certificate validation error. (#30521) * Fixes an issue where fonts were not correctly included in the PDF resulting in wrongly rendered free text annotations. (#30115) * Fixes an issue where highlight annotations used the wrong blend mode after importing with Instant JSON. (#30537) * Fixes inaccessible files possibly being erroneously reported as corrupted. (#29556) * Fixes an out of bounds page index access that could occur during note annotation saving in multi-provider documents. (#30742) * Fixes annotations being rotated incorrectly when using a custom annotation provider and temporary rotation (`setRotationOffset`) and saving more than once. (#30730) ### Examples * Fixes arrow key control not working in the Snake example. (#30552) ## 10.5.1 — 11 Aug 2021 ### PSPDFKitUI * Adds the `clearOrDeleteAllAnnotations` subclassing hook for `AnnotationTableViewController`. (#30183) * Adds an accessibility identifier to the page label. (#30158) * Improves transition animations to and from the thumbnail view mode. (#30464) * Fixes a crash introduced in 10.5 that occurred when trying to search in the annotation list. (#30411) * Fixes an assertion failure that was hit when reloading the thumbnail controller before it was loaded. (#30384) * Fixes an issue where rotating the device after navigating to a specific page could result in a previously viewed page being shown. (#28561) * Fixes an issue where the search bar in `SearchViewController` could be scrolled past the visible area when there were no search results. (#29721) ### PSPDFKit * API: The `PSPDFDocumentWillSaveAnnotationsNotification` notification has been refined for Swift as `Document.willSaveAnnotations`. (#29518) * Improves freetext annotation rendering across PSPDFKit platforms by honoring the `isFitting` attribute from Instant JSON. (#28719) * Fixes the page render disk cache not inheriting the file protection level of the cache directory and instead using the default protection level of the container as set in the entitlements file. This only applies to newly cached images. To ensure old cached images are not using an incorrect protection level, please either clear the disk cache or enumerate the contents of the cache directory and set the file protection level as desired. (#30430) * Fixes the PDF table of contents (outline) linking to the wrong page in certain documents. (#30070) * Fixes a rare crash that may happen when rendering certain PDFs. (#29843) * Fixes XFDF annotations like lines without an explicit `width` attribute not being rendered. In these cases, PSPDFKit now mimics Acrobat’s behavior and implies a line width of 1 pt. (#30291, Z#25968) * Fixes fine-grained page reloading not always calling the correct document provider creation callback method. (#29518) * Fixes undoing removing an annotation resulting in the annotation being added at an incorrect page index when using a document with multiple document providers. (#30329) ### Examples * Adds a new SwiftUI example that demonstrates how to display a custom annotation inspector. (#30099) * Adds support for fetching thumbnails from a remote source in the streaming document example. (#29518) * Adds support for external annotation sources and pageIndex-aware downloading in the streaming document example. (#29518) ## 10.5.0 — 5 Jul 2021 _See the [announcement post](https://www.nutrient.io/blog/pspdfkit-10-5-ios-instant-document-permissions/)._ In preparation for iOS 15, this version of PSPDFKit now drops support for iOS 12. (#29669) ### PSPDFKitUI * API: Changes a property attribute of `AnnotationStateManager.pencilInteraction` from `nullable` to `nonnull`, since it will never be `nil` on iOS versions above 12.1. (#29985) * Deprecates all API related to page grabber: `PDFViewController.pageGrabberController`, `PageGrabber`, `PageGrabberView`, `PageGrabberController`, `PDFConfiguration.pageGrabberEnabled` and `PDFView.pageGrabberEnabled`. These are no longer needed because the scroll indicator from `UIScrollView` supports dragging on iOS 13 and later. (#30004) * Deprecates `appearanceManager(_:applyAppearanceSettingsForMode:)` and `appearanceManager(_:updateConfiguration:forMode:)` methods of `AppearanceModeManagerDelegate` since they are replaced by the `overrideUserInterfaceStyle` property on UIView and UIViewController on iOS 13 and later. (#29820) * Deprecates `tabBarStyle` from `PDFTabbedBar`. (#29820) * Adds `pageDescriptionProvider` and `selectedPagesDescriptionProvider` properties on `DocumentSharingConfiguration` to enable customizing how pages are described in the sharing UI. See the new PageLabelsInSharingExample.swift example in the Catalog for details. (#27826) * Removes full-page 3D Touch previews from `AnnotationTableViewController`, `BookmarkViewController`, `OutlineViewController` and `SearchViewController`. 3D Touch will now show a contextual menu instead. (#29892) * Thumbnail grid cells now automatically scale images if a custom `PDFPageCellImageLoading` image loader is used that returns images that are too large. (#29518) * Fixes an issue where redoing the creation of ink annotations would sometimes result in them being rendered on top of each other. (#29800, #29829) * Fixes an issue where some of the UI elements presented a `PDFViewController` did not inherit its `overrideUserInterfaceStyle`. (#29870) * Fixes an issue where the context menu under the Additional Toolbar Buttons did not show up in certain cases. (#29835) * Fixes an issue where the undo and redo toolbar buttons would not be reliably updated in certain scenarios. (#29855) * Fixes choppy page scrolling that could occur in rare cases near the first or last page in continuous scrolling mode. (#29394) * Fixes an issue when picking images from the Photo Library asking for access to the camera, which would cause the image picker to fail the first time. (#29674) * Fixes the cells in the document editor having incorrect top inset when using the `.top` toolbar position and when the toolbar was not positioned exactly at the top of the `PDFViewController`’s view. (#29891) ### PSPDFKit * Adds support for rendering pages with a transparent background. (#29867) * Changes the scaling mode for button form element images to use aspect fit to prevent images from being clipped. (#17805) * Refines `performRead(_:)`, `performWrite(_:)` and `performWriteAndWait(_:)` methods of `PDFContainerAnnotationProvider` for Swift. (#29754) * Fixes an issue where importing a 'goToRemote' without a page index would fail. (#29616) * Fixes an issue where importing unknown actions using Instant JSON failed. (#29814) * Fixes an issue where redactions of paths could fail with “Coordinate outside allowed range” if the path coordinates were very large. (#29791) * Fixes an issue where signing a document in some cases may fail without a specific error object. (Z#25217) * Fixes an issue where the Instant JSON would contain redundant data after removing a form field. (#29671) * Fixes an issue where undo and redo stacks would persist in an invalid state after saving changes in the Document Editor. (#29691) * Fixes an issue where undo and redo stacks would persist in an invalid state after setting a temporary page rotation offset. (#29924) * Fixes an issue where undoing and redoing changes made to annotations would not restore their previous custom appearance streams. (#19523) ### Instant * Adds support for Instant Document Permissions. (#29983) * Adds support for the (optional) `creator_name` claim in JWTs: Documents managed by Instant now reflect this value in their `defaultAnnotationUsername` property, if it is encoded in the JWT. As a result, all annotations and comments locally created in this `Document` will report this value as their creator. (#29507) * Fixes a lock inversion that could lead to a deadlock. (#29743) * Fixes an issue where locally created Instant comment markers could end up appearing as regular note annotations. (#30010) ### Examples * Fixes the unreachable URL for the document used in the `DocumentProgressExample` which led to the document not loading. (#29619) ## 10.4.2 — 11 Jun 2021 ### PSPDFKit * Works around a system regression with font downloading on iOS versions between 14.0.0 and 14.4.2 by selectively disabling extended font choices and related lookup code. (#29779) ## 10.4.1 — 2 Jun 2021 ### PSPDFKit * Improves the reliability of undoing annotation removal. (#29641) * Improves the reliability of undoing changes made to text markup and sound annotations. (#29594) * Fixes a crash that could occur when undoing the addition or removal of annotations. (#29594) * Fixes a performance regression, most noticeable during drawing, introduced by overly verbose logging. (#29613) * Fixes a problem where a document signed with a timestamp may not validate correctly. (#29380) * Fixes a problem where an ECDSA signature in IEEE 1363 format may not validate correctly. (#29380) * Fixes a crash that could occur in some cases when undoing resizing an image annotation. (#29595) * Fixes an issue where OCR would fail if no text is on the page. Now the call returns successfully. (#29527) * Fixes an issue with OCR where no text is found if the text on the page is relatively large. (#29512) ### Examples * Adds a new Catalog example that shows how to redact text using a regular expression. (#29528) * Fixes an issue in the `InstantDocumentViewController` where calls to present alerts were not on the main thread. (#29619) ## 10.4.0 — 20 May 2021 _See the [announcement post](https://www.nutrient.io/blog/pspdfkit-10-4-ios-new-undo-architecture/)._ To learn more about the breaking changes introduced with the new APIs, check out [our migration guide](https://www.nutrient.io/guides/ios/migration-guides/pspdfkit-10-4-migration-guide.md) for this release. ### PSPDFKitUI * Deprecates `annotationStyleController(_:willStartChangingProperty:)` method of `AnnotationStyleViewControllerDelegate` protocol in favor of `annotationStyleController(_:didBeginChangingProperty:)`.

(#29014) * Fixes glitches when using the `showAnnotationMenuAfterCreation` configuration option with text markup, note, polygon, and polyline annotations. The menu will not be shown for these annotation types after creation. (#29148) * Fixes two Speak menu items being shown for selected text when the Speak Selection accessibility setting is enabled. Only the system menu item will be shown now. (#29169) ### PSPDFKit * API: Adds a new undo architecture, which replaces the existing `UndoController` API. Please refer to the migration guide for more details. (#14301) * API: Removes the initializers of `PDFCache`, `DiskCache`, and `MemoryCache` because PSPDFKit handles creating these objects.

(#27770) * Fixes a rendering issue for specific documents that have font resources with /Widths that are too small to render. (#28103) * Fixes an issue in the text parser where space characters were being omitted from the returned text. (#28886) * Fixes an issue that caused annotation added via Instant JSON not being added to a document generated with the processor. (#29023) * Fixes an issue where JavaScript code was not executed correctly. (#29283) * Fixes an issue where PSPDFFormField could not be subclassed and overridden. (#28955) * Fixes an issue where an invalid digital signature may return the same error code more than once. (#27512) * Fixes an issue where form fields are not interactive after a document with JavaScript is merged with another document. (#28052) * Fixes an issue where list boxes would not render text when an item is selected if there was no DA field present.

(#28092) * API: `KeychainSignatureStore` may now be initialized without a `storeName` to use the default store name. (#28092) * API: Removes `UIHostingView` class. Please use your own helpers for interoperability between SwiftUI and UIKit. (#28229) * Deprecates `SegmentedControl` class. Please consider creating your own segmented control subclass. (#24801) * Adds `PDFViewController.selectedAnnotations` property to get or set the selected annotations inside a view controller. (#27878) * Adds `signatureButtonItem` property to `PDFViewController` that shows the signing UI. Requires the Electronic Signatures feature to be present in your license. This button is enabled by default when Electronic Signatures are enabled and Annotations are not enabled. (#27404) * Adds `Annotation.Tool.iconImage(with:)` function that can be used to get an icon for an annotation type. (#28023) * Adds additional actions to the SwiftUI `ActionEvent` publisher. (#28470) * Adds support for playing back audio from hidden video and audio annotations. (#27488) * Adds support for adding links to reading list when long-pressing on a link annotation in a Mac Catalyst app on macOS Big Sur.

(#28158) * New page actions without a sender are now better handled by the Document Editor. (#28112) * Fixes a crash that would occur when panning a page while zoomed in using `.curl` page transition. (#26690) * Fixes `SignatureViewController` initialization to enable correct override behavior from Swift. (#28321) * Fixes an issue where removing an already deleted PDF file that was temporarily generated for sharing purposes would log a warning. (#28382) * Fixes an issue where an ink annotation could sometimes not be erased when zoomed in. (#26829) * Fixes an issue where `PDFViewController` would sometimes stop responding to touches after cancelling a sharing activity. (#28382) * Fixes an issue where the button for adding a reply was not disabled whilst editing an annotation reply. (#28342) * Fixes an issue where the search popover would not correctly resize in a Mac Catalyst app on macOS Big Sur. (#28312) * Fixes an issue where selecting multiple annotations would use reverse the order when sorting annotations. (#28311) * Fixes an issue where using `PDFView` in SwiftUI could trigger a runtime warning for state modification during view update. (#28444) ### PSPDFKit * API: `DataProviding` protocol has breaking changes to include error propagation on most access methods. (#28530) * API: `MenuItem.identifier` must be set during initialization. The property is now read-only to reflect this design. (#28318) * Deprecates `SignatureContainer.init(annotation:signer:biometricProperties:)` in favor of `init(signatureAnnotation:signer:biometricProperties:)` that supports image signatures with the new Electronic Signatures component. (#27404) * Deprecates `SignatureContainer.annotation` property in favor of `signatureAnnotation` that supports image signatures with the new Electronic Signatures component. (#27404) * Adds `StampAnnotation.isSignature` property to support image signatures with the new Electronic Signatures component.

(#28530) * Improves the saving experience in the Document Editor and Redaction components by displaying the system picker immediately if there are no other directory choices available. (#27948) * Improves RGB color space conversion for annotation colors to make it more resilient to arbitrary input. (#27652) * Improves file coordination when interacting with `NSDocument` in a Mac Catalyst app. (#28555) * Serializing the standard document configuration now includes bookmark data that can be loaded in a sandboxed Mac Catalyst app. Make sure to set `com.apple.security.files.bookmarks.document-scope` in your Entitlements file so that macOS allows bookmark deserialization. (#28343) * Updates FreeType to 2.10.4.106. (#27771) * Updates libjpeg-turbo to 2.0.90. (#27771) * Fixes a regression where custom blend mode of an annotation would no longer be stored in the PDF when the annotation had the `.invisible` flag set. (#28422, Z#23418) * Fixes a performance regression when using `RenderOptions.additionalCIFilters`. When using the same set of filters with different input parameters, please refer to the documentation of this property for more details.

(#23123) ## 9.4.0 — 16 Jun 2020 _See the [announcement post](https://www.nutrient.io/blog/pspdfkit-ios-9-4/)._ This release adds the [Reader View](https://www.nutrient.io/guides/ios/features/reader-view.md) component, as well as [Office Files Support](https://www.nutrient.io/guides/web/conversion/office-to-pdf.md). If you would like to obtain PSPDFKit Server or add either to your license, [ping our sales team](https://www.nutrient.io/support/request) to receive a quote. In preparation for iOS 14, this version of PSPDFKit now drops support for iOS 11. It also requires and is built with Xcode 11.5 (11E608c). PSPDFKit and PSPDFKitUI now also come with a stable module interface. This enables linking with PSPDFKit frameworks, even if the Swift compiler version used in your application differs from the one we used to build the frameworks. This release has some smaller breaking API changes. Please see [our migration guide](https://www.nutrient.io/guides/ios/migration-guides/pspdfkit-9-4-migration-guide.md) for details. ### PSPDFKitUI * API: Replaces the `LinkAnnotationEditingContainerViewController.init(page:, selectedRects:)` initializer with `LinkAnnotationEditingContainerViewController.init(document:, pageIndex:, selectedRects:)`. Page objects cannot be created outside of PSPDFKit so the previous initializer was not usable as public API. (#24413) * API: Changes the type of the `pointSequences` property on `DrawView` from `[[NSValue]]` to `[[DrawingPoint]]` in Swift (#23734) * API: `PSPDFDocumentViewLayoutPageMode` has been renamed to `PDFDocumentViewLayout.PageMode` in Swift. (#23861) * API: `PSPDFDocumentViewLayoutSpreadMode` has been renamed to `PDFDocumentViewLayout.SpreadMode` in Swift.

(#24223) * Deprecates the `longPressGestureRecognizer` property on `BackForwardButton`, `ToolbarGroupButton`, and `ToolbarDualButton` since these are not always used by PSPDFKit itself. (#23878) * Adds Reader View: A new component that reformats document text into an easy-to-read, single-column view that’s optimized for mobile devices. (#23580) * Adds a workaround for an OS issue where text input on Mac Catalyst could cause a memory race on macOS 10.15.4 and 10.5.5. (#24390) * Adds contextual menus on tabbed bar to close tabs on iOS 13. Earlier versions show an action sheet on long press as before. The menu or sheet can now be activated from anywhere on the tab rather than just the close button. (#23878) * Adds explanatory text at the bottom of `PDFDocumentSecurityViewController` when `SDK.Setting.honorDocumentPermissions` is disabled to clarify that restricting permissions will not change behavior in the app. To hide this message, use `setLocalizationDictionary` or `setLocalizationClosure` to use an empty string for the key `DocumentSecurity_PermissionsDisabledExplanation`. (#23857) * Adds showing the annotation inspector’s color preset reset menu immediately in response a secondary click on a trackpad or mouse. This enhancement requires `UIApplicationSupportsIndirectInputEvents` to be enabled in your app’s Info.plist. (#23878) * Adds subtle trackpad and mouse hover effects to many parts of the UI. (#23641) * Adds support for enabling `UIApplicationSupportsIndirectInputEvents` in the app‘s Info.plist. (#24026) * Adds support for sharing documents with unsaved changes.

(#24095) * Improves the history list on the back and forward navigation buttons by using a system contextual menu. (#23878) * Improves the snapping behavior of the annotation toolbar in some edge cases. (#23751) * Changes the behavior of `FlexibleToolbar` so that it can no longer be dragged if `supportedToolbarPositions` has only one value. (#23655) * Fixed an issue where `TextSelectionView.selectedText` would return an empty string instead of `nil` if no text was selected. (#23946) * Text to speech now uses a more accurate way to autodetect the document language. (#24223) * Works around issue which caused the annotation toolbar to lose its background when the window loses focus on Mac Catalyst. (#21711) * Fixes an issue that could invoke PDF actions from multiple annotations simultaneously during a tap event, if the annotations were in close proximity. (#23456, #23845) * Fixes an issue where switching page transition from continuous to curl caused the page to get zoomed in. (#21266) * Fixes an issue where the scrubber bar page markers were not updated correctly while using double page mode. (#24144, #24149) * Fixes annotation summary sharing (`DocumentSharingConfiguration.AnnotationOptions.summary`) not working if the license does not include the WebKit-based HTML to PDF conversion feature. (#24339) * Fixes the window document reference being set even if `allowWindowTitleChange` was disabled on Mac Catalyst. (#23773) ### PSPDFKit * API: Changes the `PSPDFObject` string constants to an extensible enum `PSPDFObjectFinderOption`. Also introduces a new extensible enum `PSPDFObjectFinderType` to separate the output types from the options. (#24343) * API: Changes the type of the options dictionary keys on the `URLAction` initialiser from `String` to `Action.Option`. (Only affects Swift). (#23831) * API: Changes the type of the options parameter of `annotationsByDetectingLinkTypes:forPagesAtIndexes:options:progress:error:` from `NSDictionary *> *> *` to `NSDictionary *> *> *`. (#24343) * API: Changes the type of the options parameter of `objectsAtPDFPoint:pageIndex:options:` and `objectsAtPDFRect:pageIndex:options:` from `NSDictionary *` to `NSDictionary *`. (#24343) * API: In the `PSPDFPageView` class, changes the type of the options param in `objectsAtPoint:options:` and `objectsAtRect:options:` from `NSDictionary *` to `NSDictionary *` and return type from `NSDictionary *` to `NSDictionary *`. (#24343) * API: Removes the Swift free function `BoundingBoxFromLines`. (#24435) * API: Removes the `PDFPage` class, as it was not possible to create or obtain `PDFPage` objects via public API. (#24413) * API: Renames `PDFFileAnnotationPovider` to `PDFFileAnnotationProvider` (only affects Swift). (#24072) * API: Renames `PDFSigner.Error` to `PDFSignerError` in Swift. This is a breaking change with no deprecation in order to avoid ambiguity with the `Swift.Error` type. (#23912) * API: The `Processor` class methods `generatePDF(from...)` now have a non-optional return type and call their completion handler with an error if the required feature is missing in the license. (#24352) * API: The behavior of the `editable` property of `Annotation` was changed slightly. It now also depends on the `readOnly` property. (#23868) * Deprecates the constants used for searching text using `PDFLibrary` API in favor of new constants of type `PDFLibrary.Option`. (#24215) * Deprecates the `BackForwardActionListDelegate` methods `backForwardList(_:requestedBackActionExecution:)` and `backForwardList(_:requestedForwardActionExecution:)`, and the `BackForwardActionList` methods `requestBack`, `requestBack(to:)`, `requestForward`, and `requestForward(to:)` in favor of variants with an `animated` parameter. (#23791) * Deprecates the type aliases `PDFLine` and `ViewLine` because their names were inaccurate. (#24433) * Deprecates `AESCryptoInputStreamErrorCode` renaming it to `AESCryptoInputStreamError` in Swift. Xcode will provide an automatic fix.

(#23385) * Fixes an issue where attempting to access link annotations that reference remote destinations containing certain characters could lead to a failed assertion. (#24212) * Fixes an issue where combo boxes with attached JavaScript actions would fail to execute the attached actions when changing their value. (#23120) * Fixes an issue where text was rendered incorrectly when the 'comb' option was used. (#24395) * Fixes an issue where the read-only property of an annotation would get ignored if the annotation had a user, allowing it to be erasable. (#23868) * Fixes an issue where using a custom background color filled the rendered image beyond the page bounds. (#22590) ### Instant * API: `PSPDFInstantDocumentState` has been renamed to `InstantDocumentState` in Swift. (#24215) * API: `PSPDFInstantSyncingLocalChangesDisabled` has been renamed to `InstantSyncingLocalChangesDisabled` in Swift. (#24215) * Adds a new error code to `InstantError` for the case where syncing fails due to the size of the sync payload exceeding the server limit: `.payloadLimitExceeded`.

(#22805) ### PSPDFKit * API: In Objective-C, the `fields` property of `PSPDFAbstractFormAnnotation` is now typed `NSArray> *` to more clearly document what this property contains. In Swift, this property has been refined as `var fieldIdentifiers: [FormFieldIdentifier]?`. (#23596) * API: Renames the `PSPDFReachability` `enum` to `PSPDFReachabilityStatus`. (#23636) * API: Updates the update block in `-[PSPDFAnnotationManager updateAnnotationsOnPageAtIndex:error:withUpdateBlock:]` to allow reporting errors occurred in the block. (#23517) * API: `PSPDFAnnotationWriteOptions` type has been renamed to `PSPDFAnnotationWriteOption`. Along with it, its constant `PSPDFAnnotationWriteOptionsGenerateAppearanceStreamForTypeKey` has been renamed to `PSPDFAnnotationWriteOptionGenerateAppearanceStreamForType`. (#23539) * Removes entries for the localized string key `"Could not retrieve the signature contents"`. Use `"Could not retrieve the signature contents."` (with period at end) instead.

(#23337) * Added an example that illustrates how to programmatically create a new free text annotation, such that the user can immediately start typing. (Z#17749) ## 9.2.2 — 18 Feb 2020 ### PSPDFKitUI * Fixes an issue where the scrollable thumbnail bar didn't update a page image when annotations were added, changed, or deleted on a page. (#23146) * Fixes an issue where we could assert in `[PSPDFDocumentViewTouchHandler presentationContext]` when the view controller is dismissed while a tap is handled in the same runloop. (#23183) ### PSPDFKit * Fixes an issue where Helvetica-Bold wasn't displayed correctly. (#22664) * Fixes an issue where form field elements would not be fillable even if their backing form field was not readonly. (#21061) * Fixes an issue where some PDF JavaScript calculations may not work correctly. (#23043) * Fixes an issue where the mailDoc and similar JavaScript functions may not parse their arguments correctly. (#23257) * Fixes empty text form fields not rendering their background color.

(#23061) ### PSPDFKit * Fixes `-[PSPDFAnnotationSet initWithAnnotations:copyAnnotations:]` not normalizing bounding boxes like its deprecated variant did. (#23061) ## 9.2.0 — 21 Jan 2020 _See the [announcement post](https://www.nutrient.io/blog/pspdfkit-ios-9-2/) and [migration guide](https://www.nutrient.io/guides/ios/migration-guides/pspdfkit-9-2-migration-guide.md) for this release._ ### PSPDFKitUI * API: The `color` property of `PSPDFColorButton` is now correctly marked as optional/nullable. (#22695) * API: Removes support for 3rd-party styluses. (#22628) * Deprecates `PSPDFImageQualityHigh`, replacing it with `PSPDFImageQualityBest`. (#22763) * Adds Dark Mode support to the notes and comments screen (`PSPDFNoteAnnotationViewController`). (#21333) * Adds a high quality option to the image picker (`PSPDFImageQualityHigher`).

(#22685) * Improves `PSPDFAnnotationGridViewController` so it shows more annotations when the view is larger (wider than 700 points). (#21423) * Improves logic around the image picker to no longer require the `NSPhotoLibraryUsageDescription` permission in your app's `Info.plist`. (#21778) * Improves performance and smoothness of animations in `PSPDFAnnotationTableViewController` when annotation updates occur. (#22831) * Improves some error alert titles. (#22757) * Improves the ordering of the key commands exposed by `PSPDFNavigationController` so their order in the discoverability overlay matches the reading order of the bar buttons on screen. (#22635) * Improves the page selection logic to pick the most recently interacted page when switching from landscape to portrait in page curl mode. (#20452) * Improves the stamp annotation creation process by reducing the copying of annotations when creating them via the saved annotations picker or the stamps picker user interface. (#22666) * Improves the styling of the accessory view used in the `PSPDFChoiceFormEditorViewController`. (#19936) * Changes the approximate image size for `PSPDFImageQualityMedium` from 1024 × 768 to 1600 × 1200 because the previous size was very close to `PSPDFImageQualityLow`. (#22763) * Changes the behavior of the popover presenting `PSPDFChoiceFormEditorViewController` to allow dismissing the controller on tapping outside of it. (#22852) * Changes the hardware keyboard command to select the top/bottom item in a list from command up/down arrow to option up/down arrow in order to match standard Mac behavior. (#22683) * Floating keyboards now no longer trigger keyboard avoidance actions on `PSPDFAvoidingScrollView` subclasses apart from free-text annotation avoidance. (#22436) * Improve contrast, especially in Dark Mode, of some tinted UI elements such as text in the outline and icons in the annotation list. (#22197) * Makes the background in the image editor use a translucent color, to see the cut off part of the image. (#22914) * Synchronizes the default `borderEffectIntensity` for cloudy borders with other PSPDFKit platforms. The default intensity when switching to cloudy borders via the PSPDFKit UI is now `2` instead of `3`. (#22611) * The image quality picker of `PSPDFImagePickerController` is now enabled by default. Set its `allowedImageQualities` to `PSPDFImageQualityBest` to disable this. (#22763) * The thumbnail grid now reloads in a more efficient way when bookmarks are changed while it is displayed. (#22687) * Using the keyboard shortcut to select all text or annotations on Mac Catalyst no longer shows the selection menu automatically. (#22651) * `PSPDFBrightnessManager` has a new mode to disable the idle timer completely. (#22802) * Fixes an issue where `-[PSPDFPageView annotationViewForAnnotation:]` might have returned the wrong value, and improves the documentation of this method. (#22578) * Fixes an issue where `PSPDFNavigationController` would pass the wrong item in the delegate callback `navigationBar:shouldPopItem:` when going back using a hardware keyboard. (#22635) * Fixes an issue where changing pages would not work on the first and last pages on documents with a right page binding in the curl transition. (#22668) * Fixes an issue where ink annotations drawn using Apple Pencil would create a temporary copy when moved while still in edit mode.

(#21187, Z#16604) * Fixes an issue where the `PSPDFTabbedBar`'s add document and overview buttons could have clear backgrounds. (#21725) * Fixes an issue where the image in the image editor might be shown partially behind the navigation bar. It is now centered inside the safe area without being occluded. (#22914) * Fixes an issue where the popover presented in the `PSPDFTabbedViewController` with list of open documents was not dismissed when the button presenting it was hidden. (#22799) * Fixes an issue where the scrubber bar would have the wrong page marker set when reacting to a new document being set on the `PSPDFViewController`. (#22739) * Fixes the annotation list not updating when annotations change while the list is visible. (#22789) ### PSPDFKit * API: Changes the localized string key `Redact` to be for the redaction annotation type instead of the word “Redact”, which is no longer translated by PSPDFKit. In other words, the key `Redact` was removed and then the key `Redaction` was changed to `Redact` to match the PDF specification. The best way to get this localized string key is to use the constant `PSPDFAnnotationStringRedaction`. (#21243) * API: Changes the localized string key for the file annotation type from `File` to `FileAttachment` to match the PDF specification. The best way to get this localized string key is to use the constant `PSPDFAnnotationStringFile`. (#21243) * API: Changes the localized string key for the free text annotation type to only `FreeText`. The duplicate entry with the key `Text` is now used for note annotations to match the PDF specification. The best way to get this localized string key is to use the constant `PSPDFAnnotationStringFreeText`. (#21243) * API: Changes the localized string key for the note annotation type from `Note` to `Text` to match the PDF specification. The best way to get this localized string key is to use the constant `PSPDFAnnotationStringNote`.

(#22791) * Removes the localized strings entry with the key `Squiggle`, which was not used. The localized text for the squiggly annotation type has changed to ‘Squiggle’ using the key `Squiggly` as before. The best way to get this localized string key is to use the constant `PSPDFAnnotationStringSquiggly`. (#22861) * Uses modern `NSFontDescriptor` enums on macOS for better Swift bindings. (#22678) * Fixes a problem where encrypted documents could not be digitally signed correctly. (#22722) * Fixes a problem where some PDF pages may not be rendered correctly. (#22767) * Fixes an issue that caused a blank page after flattening annotations on a certain document. (#22279) * Fixes an issue where characters weren't escaped correctly when exporting XFDF.

(#20512) * Fixes an issue where multiple form elements that are related to the same form field could not be targeted as a group in JavaScript actions, as described by the PDF Reference. The form elements can still be addressed individually by appending `.x` to the (fully qualified) name of the form field, where x is the index of the form element in the `annotations` property of the `PSPDFFormField`. (#22755) * Fixes an issue where popup annotations were positioned incorrectly. (#22730) * Fixes an issue where text is not displayed in small free-text annotations. (#22514) * Fixes an issue where the file size optimization algorithm didn't run. (#22809) * Fixes an issue where the outline was overridden if set, before property was accessed. (#22678) * Fixes an issue where toggling eraser on a page with temporary rotation rendered ink annotations in a regressed state. (#22434) * Fixes an issue which led to bookmarks not getting updated when importing InstantJSON. (#22198) * Fixes an issue with creating a Submit Form action from JSON without action flags.

(#22675) ### Instant * Improves the responsiveness of moving and scaling image annotations by avoiding unnecessary work. (#22578) * Fixes a deadlock that could occur when changes were accumulated while a sync was already in progress. (#22703) * Fixes an issue where stamps created on the iOS device would immediately vanish when deselected, and never synced. (#19742) * Fixes an issue where shape annotations would grow temporarily when another shape annotation was drawn immediately afterwards. (#20236) ### Examples * Renamed `PSCAddingButtonExample.m` to PSCAddingCustomViewsExample.m and improved the example which now demonstrates how to add overlay views that stay aligned with PDF content. (#21704) * Fixes the close button in the document view not always working in the Split View Controller Sidebar example.

(#22479) * Adds support for selecting ranges of pages in the Document Editor UI by dragging with two fingers. This can be disabled by subclassing `PSPDFDocumentEditorViewController` and overriding `collectionView:shouldBeginMultipleSelectionInteractionAtIndexPath:` to return false. (#22536) * Adds a new keyboard shortcut (Command + option + G) to jump to a page. (#22291) * Adds a subclassing hook to customize document saving when the app is saved for the various autosave reason (backgrounding, terminating,...). (#22077) * Improves conflict resolution handling after file deletion by automatically removing deleted documents from built-in view controllers when the documents don't have any unsaved changes and are not currently being displayed. (#22025) * Improves page rendering when a zoomed window is resized. (#21836) * Improves smart thumbnail size calculation to show more thumbnails on larger screens. This is especially beneficial with Mac Catalyst. (#21424) * Improves the layout of the color presets in the annotation inspector on larger devices. (#21777) * Note annotations can now be moved faster on iPad and Mac Catalyst. The detail view animation is now instant. (#22303) * The delegate methods on `PSPDFSpeechController` are now always called on the main thread. (#22301) * The security part of the document info view is now shown as a separate item in the segmented control. See `PSPDFDocumentInfoOptionSecurity` to add or remove this new item.

(#21766) ## 9.0.0 — 19 Sep 2019 _See the [announcement post](https://www.nutrient.io/blog/pspdfkit-ios-9/)._ PSPDFKit now requires and is built with Xcode 11.0. This release features support for a new platform - Mac Catalyst. Be sure to check out our [Introducing PSPDFKit for Mac Catalyst](https://www.nutrient.io/blog/pspdfkit-for-mac-catalyst/) blog post for more information. Below is a summary of the API changes in this release. For a full list, with our suggested migration strategy for each API that has been changed or removed, please see the [migration guide](https://www.nutrient.io/guides/ios/migration-guides/pspdfkit-9-migration-guide.md). The guide also provides migration steps for `xcframework` integration and the removal of `PSPDFKitSwift`. * Removes all previously deprecated API. Please see our PSPDFKit 9 for iOS migration guide to learn about the appropriate migration strategy. (#20904) ### PSPDFKitUI * API: Changes `PSPDFStatusHUD` class methods and `PSPDFStatusHUDItem` push methods to take a window as parameter, as there now might be multiple status HUDs due to multi-window support on iOS 13. (#21429) * API: `PSPDFFlexibleToolbarController` methods for showing/hiding toolbar now include an optional completion block. (#19807) * API: Renames the `PSPDFConfiguration` properties `scrollOnTapPageEndEnabled`, `scrollOnTapPageEndAnimationEnabled`, and `scrollOnTapPageEndMargin` to `scrollOnEdgeTapEnabled`, `animateScrollOnEdgeTaps`, and `scrollOnEdgeTapMargin`. (#20923) * API: The designated initializer for `PSPDFViewState` has been replaced in favor of `-[PSPDFViewState initWithPageIndex:viewPort:selectionState:selectedAnnotationNames:]`. (#20655) * API: `PSPDFUsernameHelperWillDismissAlertNotification` has been replaced with `PSPDFUsernameHelperDidDismissViewNotification`. This is posted after the dismissal ends rather than before to work better with sheets on iOS 13 that can be dismissed by swiping down. (#20978) * Removes `PSPDFPresentationShouldPopoverDismissBlockKey` because API provided by UIKit should be sufficient. (#20978) * Removes `brightnessManager` property from `PSPDFBrightnessViewController` since brightness is now directly handled on the `UIScreen` instance. (#21495) * Removes brightness related properties from `PSPDFBrightnessManager`. (#21495) * Removes `interactiveReorderingGestureRecognizer` from `PSPDFTabbedBar` since the tabbed bar uses drag and drop for reordering now. (#20431) * Removes support for using `UIWebView` in `PSPDFWebViewController`. (#19807) * Adds `PSPDFDocumentInfoCoordinator.documentInfoViewController` to enable showing the document info UI in custom ways. (#19807) * Adds `PSPDFPageView` methods for showing contextual menus: `showMenuForPoint:animated:` and `showAnnotationMenuAtPoint:animated:`. (#19807) * Adds precise immediate text selection handling on Mac Catalyst. (#21012) * Adds support for attaching a user activity to a tab dragged from the tabbed bar, to allow the system opening a new window scene on iOS 13. (#20431) * Adds support for context menus to the annotation toolbar on iOS 13. (#21205) * Adds support for dragging and dropping tabs across different `PSPDFTabbedViewController` instances. This can be enabled via `allowDraggingTabsToExternalTabbedBar` and `allowDroppingTabsFromExternalTabbedBar`. (#20431) * Adds support for iOS 13 Dark Mode. (#20403) * Adds support for the new Cut/Copy/Paste gestures from iOS 13. (#21293) * Adds an option for rounded corners to the flexible toolbar and refines the default toolbar design. (#21206) * Improves compatibility with iOS 13 sheet presentations, which can be dismissed by swiping downwards. (#20978) * Improves logic to place the share activity view controller on the page when sharing an image. (#19807) * Improves the annotation line-end selection UI in the annotation style controller. (#21535, #21542) * Improves the annotation toolbar and document editor icon designs, so it's easier to distinguish them. (#21078) * Improves toolbar selection and orientation transition animations. (#21206) * Changes `PSPDFSignatureViewController` to always use a consistent aspect ratio for the signing area. Previously this was only the case on iPad. (#20978) * Changes moving tabs in the tabbed bar to use drag and drop instead of interactive reordering. (#20431) * Changes some view controllers to always use a form sheet presentation style by default: the signature view, the link annotation editing view, and the privacy access denied view shown from the new page view. (#20978) * Changes the `PSPDFNewPageViewController` presented from the document editor to uses a standard form sheet rather than our custom half modal style (in compact widths). (#20978) * Changes the minimum value of the brightness slider to 0.0 instead of 0.1 to match the range of `UIScreen.brightness`. (#21495) * File Annotations can now be deleted via the default annotation menu. (#21293) * Improved keyboard support: Command-Arrow Up/Down navigates to first/last page. (#20869) * PSPDFUndoController canUndo/canRedo now always updates correctly, even if invoked via the undo manager directly. (#19807) * Updates default values for text selection properties `textSelectionMode` and `shouldShowSelectionHandles` on Mac Catalyst and extends the documentation for `textSelectionShouldSnapToWord`. (#21012) * Fixes an iOS 13 specific unsatisfiable constraint warning on `PSPDFAnnotationStyleViewController`. (#21196) * Fixes an issue that caused the search UI to be misplaced when using the search button item action with a custom button. (#21409) * Fixes an issue where selection of a page did not persist on reordering using drag and drop interaction in the Document Editor. (#21474) * Fixes an issue where the accessibility label of a page was incorrect after reordering the page in the Document Editor. (#21474) * Fixes editing free text annotations not always showing the keyboard when using multiple windows. (#21341) * Fixes the `PSPDFDocumentSharingViewController` showing incorrect sharing options if the selected destination was set before the controller being presented. (#21410) ### PSPDFKit * API: `-[PSPDFDataProviding replaceWithDataSink:]` has been extended to include an error parameter `-[PSPDFDataProviding replaceWithDataSink:error:]`. (#14338) * API: Renames the `PSPDFKit` global singleton to `PSPDFKitGlobal` to avoid conflicts with the `PSPDFKit` module name in Swift. (#21292) * API: Swift-incompatible methods on `PSPDFProcessor` and delegate-based error and completion handling on `PSPDFProcessorDelegate` have been removed. (#21233, Z#15373) * API: The `PSPDFProcessor` PDF generation API has been converted to class methods to better isolate it from the PDF processing operations. (#21000) * API: The `PSPDFRenderOption` enumeration has been replaced with the `PSPDFRenderOptions` class that now properly supports `NSSecureCoding`. (#17342) * API: The `shouldDeleteAnnotation` property on `PSPDFAnnotation` has been replaced with `isDeletable`. (#21293) * API: `PSPDFAnnotationStyleManager` now uses `PSPDFStylePreset`, a new protocol, rather than `__kindof PSPDFModel*` to expose preset instances. (#21362) * API: `PSPDFLineAnnotation.init(point1:point2:)` is no longer a failable initializer that produces an implicitly unwrapped optional. (#21194) * API: The class property `isDeletable` on `PSPDFAnnotation` has been converted to a per-object property to include object flags. (#21293) * Removes the rendering option to disable text anti-aliasing when using the non-native text rending option. (#21204) * Removes the class property `isWritable` on `PSPDFAnnotation`. All implemented subclassed annotation and form types are writable. (#21293) * Adds `NSSecureCoding` support to `PSPDFAnnotation` and its subclasses. (#12026) * Adds `NSSecureCoding` support to `PSPDFColorPreset` and `PSPDFBorderStylePreset`. (#21362) * Adds support for setting a user activity on `PSPDFDocument`.

(#20642) * Fixes an issue where loading a document would fail if it contained JPEG2000 images not specifying a color space. (#21311) * Fixes an issue where text after signing had incorrect characters after looking at it in another viewer. (#20930) * Fixes an issue where the error object was not set in case of a failure in `-[PSPDFDataProviding replaceWithDataSink:error:]`. (#21116) * Fixes an issue where using the document editor to merge a document with many pages would lead to an out-of-memory crash. (Z#15277) * Fixes issues with transparent image stamp annotations. (#7646) * Fixes issues with transparent images in XFDF. (#9221) * Fixes some stability issues related to color space management. (#21529) * Fixes some stability issues when fonts are loaded from a document. (#21042) * Fixes some use cases where PDFs with JavaScript validation scripts may not work as expected. (#21291) ### Examples * Adds a PSPDFKit Catalog example illustrating how to show a `PSPDFViewController` in SwiftUI. (#20381) * Adds an example illustrating how to always show dark user interface style on the annotation toolbar. (#20403) * Adds multi-window support to PSPDFKit Catalog on iOS 13.

(#21276) ## 8.5.2 — 6 Sep 2019 ### PSPDFKitUI * Adds a new property on `PSPDFConfiguration` called `allowRemovingDigitalSignatures` to control whether a digital signature can be removed or not. See `DisableRemovingDigitalSignatureExample` in PSPDFKit Catalog for more details. (#20586) * Changes the designated initializer of `PSPDFSignedFormElementViewController` to the new added initializer `initWithSignatureFormElement:allowRemovingSignature:`. (#20686) * Fixes an issue where a sharing action would be executed automatically if the first sharing configuration available has no options to pick from. (#20964) * Fixes an issue where the existing configuration was not preserved while showing a new digitally signed document in a new controller. (#20686) ### PSPDFKit * Improves error reporting in `+[PSPDFAnnotation annotationFromInstantJSON:documentProvider:error:]` when the document was misconfigured. (#21177) * Improves memory usage with complex documents. (#20970) * Improves the stability of some PDF form operations. (#21032) * Improves the validation of InstantJSON in some corner cases. (#20748) * Fixes a problem where some dates may be incorrectly formatted as Sunday. (#20363) * Fixes an issue with annotation hit testing that could result in taps being received by a link annotation that was underneath another link annotation. (#21055) * Fixes an issue where link annotations with a nil border color and a valid dash array were not being rendered. (#20749) * Fixes annotations being misplaced when reopening a document that loads annotations from an external file after `setRotationOffset:forPageAtIndex:` had been used to apply a temporary rotation when that document was saved. (#20976) * Fixes annotations sometimes being blurry when reopening a document that loads annotations from an external file after `setRotationOffset:forPageAtIndex:` had been called before that document was saved. (#20976) * Fixes annotations sometimes not being saved to an external file after only annotation updates happened and `setRotationOffset:forPageAtIndex:` was called before saving. (#20976) * Fixes pasted rotated vector stamps being double rotated which resulted in clipping. (#20916) * Fixes `-[PSPDFProcessorConfiguration drawOnAllCurrentPages:]` producing offset drawing when the page has a MediaBox with a non-zero origin. (#20797) * Fixes the `drawingBlock` of `PSPDFFileAppearanceStreamGenerator` not automatically handling page rotation. (#20983) * Fixes a possible crash in certain documents due to a null dereference in `isLinkedInAcroForms`. (#21121) ### Instant * Adds a migration to populate the `isFitting` flag for all pre-existing free text annotations when appropriate, preventing the clipping of text on other platforms. This is an extension of the earlier fix which only populated this flag when an annotation was changed again. (#20727) * The `isFitting` property of free text annotations now properly reflects whether the text did fit on iOS. The text of such annotations will no longer be clipped in documents exported from PSPDFKit Server or in PSPDFKit for Web. (#20727) ### Examples * Fixes a crash that would occur when opening the Kiosk Grid example on iOS 13. (#20861) ## 8.5.1 — 8 Aug 2019 ### PSPDFKitUI * Adds `-[PSPDFDocumentSharingViewController initWithDocuments:sharingConfigurations:]` and makes it the designated initializer.

(#20826) * Improves performance when opening documents with many links. (#20786) * Fixes an issue where rotating pages using the document editor would always reset the page binding setting to the left edge. (#20732) ### Instant * Prevents text clipping on other platforms when a free text annotation was created or updated on iOS such that all text is visible. (#20727) ### Examples * Fixes `PSCFormFillingExample` to properly respect specific input formats and validations of the form fields. (#20606) ## 8.5.0 — 31 Jul 2019 _See the [announcement post](https://www.nutrient.io/blog/pspdfkit-ios-8-5/)._ PSPDFKit now requires and is built with Xcode 10.3 (10G8). * Adds an optional JSON Podspec (`podspec.json`) that you can use by appending `.json` to your podspec link. Learn more in our [CocoaPods guide](https://www.nutrient.io/sdk/ios/getting-started/ios-cocoapods.md#use-json-podspec). (#20335) ### PSPDFKitUI * API: The `PSPDFDocumentInfoCoordinator`'s delegate property is now of type `PSPDFDocumentInfoCoordinatorDelegate`, which is a newly introduced protocol. (#20469) * Deprecates `PSPDFSignatureViewController`’s `lines` property in favor of its `drawView.pointSequences`. (#20450) * Adds the ability for users to change the order in which annotations are stacked on the page (the z-index) from either the annotation inspector or the annotation list. (#100) * Adds the ability for users to change the document’s page binding in `PSPDFDocumentInfoViewController`. (#10603) * Adds a unified color palette. This replaces the rainbow, modern, vintage, and monochrome color palettes in the default color set provided when creating and editing annotations. (#20212) * Adds a `halfModalStyle` property to `PSPDFConfiguration` to allow the use of the annotation inspector without the card design introduced in PSPDFKit 8.4 for iOS. (#19944) * Adds a `PSPDFDocumentInfoViewControllerDelegate` protocol to respond to changes from `PSPDFDocumentInfoViewController`. (#20510) * Changes links to open in Safari by default, because we believe this provides a better user experience. This can be changed back to `SFSafariViewController` (the in-app browser) by setting `PSPDFConfiguration.linkAction` to `PSPDFLinkActionInlineBrowser`. (#20692) * Disables natural drawing for ink annotations by default because it can sometimes produce artifacts at line ends. This can be changed back using `PSPDFConfiguration.naturalDrawingAnnotationEnabled`. (Z#14856) * Reduces the minimum line width for ink annotations from 0.5 to 0.1 in the annotation inspector. (#20654) * Fixes an issue that caused certain pages to fade from black on iOS 13 when they were moved on-screen.

(#20643) * Adds support for preserving the Instant JSON id in the PDF. (#20572) * Adds support for serializing and deserializing border properties of link annotations. (#20359) * Add support for vertical alignment in single-line form fields when exporting or printing PDF files. (#19882) * The `pageBinding` property setter of `PSPDFDocument` now saves the page binding into the document instead of just keeping it in memory.

(#20424) * Fixes page indices being incorrect after the first data provider when exporting Instant JSON from a document with multiple data providers. (#20343) * Fixes a crash that would occur after applying an Instant JSON update to a document where the changes contained form field updates. (#20152) * Fixes an issue where form fields with calculation order may not be flattened correctly by the processor. (#20434) * Fixes an issue where some documents with dropdown fields may show an arrow when the document is flattened. (#9539) * Fixes a problem where overriding the digital signature reserved size may corrupt the signature appearance. (#20496) * Fixes an issue that may prevent documents with certain restrictions from being digitally signed. (#20741) * Fixes an issue where a custom `dataSource` set on a `PSPDFSigner` object was overridden sometimes. (#20487) * Fixes an issue where some documents signed with invisible signatures could not be validated correctly. (#20277) ### Examples * Adds a Swift counterpart to the example `PSCSaveAsPDFExample.m` called `SaveAsPDFExample.swift`. (#20672) ## 8.4.2 — 5 Jul 2019 ### PSPDFKitUI * Adds the ability to cut or copy pages from the `PSPDFDocumentEditorViewController` and paste them into other applications.

(#18987) * Fixes internal document references not being retained when cutting and pasting pages in `PSPDFDocumentEditorViewController`. These are now preserved so PDF GoTo Actions still work after saving. (#19470) * Fixes an issue where annotation property changes from the inspector were not preserved when killing the app before exiting the annotation state. (#20232) * Fixes images having a low resolution after being attached to form elements using the `buttonImportIcon` JavaScript API. Images will now be added at full resolution. (Z#14555) * Fixes incorrect group spacing and cell layout issues on the sharing UI.

(#20180) ### Examples * Adds a PSPDFKit Catalog example illustrating how to persist `PSPDFSettingsViewController` settings in `NSUserDefaults`. (#20210) * Improves `DrawOnPagesExample.swift` to show how to draw multiple watermarks with different attributes. (#18922) ## 8.4.0 — 30 May 2019 _See the [announcement post](https://www.nutrient.io/blog/pspdfkit-ios-8-4/)._ ### PSPDFKitUI * Deprecates `-[PSPDFDigitalSignatureCoordinator presentSignedDocument:showingPageIndex:]` in favor of `presentSignedDocument:showingPageIndex:withPresentationContext:` to make presenting the signed document easier. (Z#13752) * Deprecates `PSPDFUserInterfaceView.thumbnailBarInsets`, which did not do anything. (#19771) * Removes the `optionsView` property from `PSPDFNoteAnnotationViewController(SubclassingHooks)` because returning any other value would lead to a crash. (#19841) * Removes the declarations of `-configureZoomView:forSpreadIndex:`, and `-configureScrollView:` from `PSPDFDocumentViewLayout(Subclassing)`. These methods were unimplemented, and not used internally. Calling them would have lead to an “unrecognized selector” crash. (#19841) * Removes the unimplemented `PSPDFPageLabelView(SubclassingHooks)` category. (#19841) * Removes the unimplemented subclassing hooks `-cancelDrawingAnimated:` and `-doneDrawingAnimated:` from `PSPDFAnnotationStateManager`. (#19841) * Removes the unimplemented category `PSPDFSavedAnnotationsViewController(SubclassingHooks)`. Calling the method it declared would have lead to an “unrecognized selector” crash. (#19841) * Adds a new look and feel for the scrubber bar, which now appears to be floating in the user interface. To revert to the old design, set `thumbnailBarMode` to `PSPDFThumbnailBarModeDockedScrubberBar` in `PSPDFConfiguration`. (#16110) * Adds an improved, modern visual design for the annotation inspector. (#19053) * Adds support for rotating free text annotations to any angle. (#15900) * Adds the ability to customize the eraser thickness in the UI which can be changed in the Annotation Inspector invoked from the Annotation Toolbar.

(#19985) * Adds a subclassing hook, `-[PSPDFUserInterfaceView updatePageLabelFrameAnimated:]`, for changing the page label position. (#19217) * Adds ``. This protocol documents the API requirements for the object returned by the `webView` property of `PSPDFWebViewController`. It acts as an abstraction of the common API of `UIWebView` and `WKWebView`, as used by our view controller. (#19841) * Adds biometric properties on `PSPDFDrawView`: `pointSequences`, `pressureList`, `timePoints`, `touchRadii` and `inputMethod`. Calling `clear` on `PSPDFDrawView` now also clears any currently collected biometric data. (#19800) * Marks the inherited initializer `-[PSPDFMenuItem initWithTitle:action:]` as unavailable because it cannot be used with this class. (#19841) * Moves `PSPDFGalleryItem(Protected)` into a separate header file, and turned it into a class continuation. For subclassing `PSPDFGalleryItem`, please use `#import ` now. (#19841) * Promotes the declaration of `-updatePageLabel` in `PSPDFThumbnailGridViewCell(SubclassingHooks)` up the class hierarchy to `PSPDFPageCell`. (#19841) * Single-page documents now have the thumbnail bar hidden by default. A new property in `PSPDFConfiguration` (`hideThumbnailBarForSinglePageDocuments`) lets you configure this behavior. (#16110) * Fixes a crash that could occur in `-[PSPDFThumbnailFlowLayout ensureLayoutAttributesForItemsUpTo:]` when viewing page thumbnails in double page mode. (#19984) * Fixes a regression introduced in PSPDFKit 8.3.2 where the header in the thumbnail layout would be misplaced after rotation, and the sticky header would not stick. (Z#13392) * Fixes an issue where an annotation’s `fillColor` returned `UIColor.clearColor` instead of `nil` for a clear color. (#19896) * Fixes an issue where annotations drawn in dark mode had a black fill color instead of a clear fill color. (#19831) * Fixes an issue where erasing or undoing an ink annotation changed the alpha of the remainder of the drawn ink annotation on page. (#19900) ### PSPDFKit * API: Replaces the `rotation` property setter of `PSPDFFreeTextAnnotation` with `setRotation:updateBoundingBox:`, which is declared in the `PSPDFRotatable` protocol. (#19983) * Adds Welsh localization. (#19923) * Adds a new `PSPDFPKCS7` class for representing a digital signature PKCS7 container. (#19916) * Adds a way to construct an instance of a `PSPDFPrivateKey` from `NSData` that represents a valid private key in either PKCS1 or PKCS8 encoding format. (#19916) * Adds embedSignatureInFormElement: API to the `PSPDFSigner`, an API that embeds a digital signature in a document already prepared to contain a digital signature. (#19479) * Adds `hashDocumentProviderRange:` API to the `PSPDFDocumentProvider`, an API that returns a hashed part of a document provider, indicated by a particular byte range. Useful for creating digital signatures. (#19479) * Adds `prepareFormElementToBeSigned:` API to the `PSPDFSigner`, an API that reserves space in a signature form field so that it can be signed later. (#19479) * Adds the ability to set a custom signature watermark. (#19438) * Adds support for the `Doc.documentFileName` JavaScript API. (#18775) * Makes enums use `NS_CLOSED_ENUM` so Swift callers don’t need to handle unknown cases. (#18679) * Improves rendering of text in appearance streams. (#19877) * Improves the performance of some JavaScript calculation scripts. (#19234) * Embedded goto actions will go to the specified page instead of going to the first page of the embedded target document. (#10963) * Improves automatic repair of AcroForms to support more document errors. (#19834) * Renames `PSPDFSignatureInputMethod` enum to `PSPDFDrawInputMethod`. The previous values have been deprecated. (#19800) * Updates Expat to version 2.2.6. (#19868) * Updates the Botan library version to 2.10.0. (#19767) * Fixes a bug which caused the font picker to scroll to the selected item with a jerky animation. (#19108) * Fixes an issue creating form fields where some fields could not be retrieved later by their original keys. (#19945) * Fixes an issue where JavaScript API `doc.getField()` could get into a state where it wasn’t possible to retrieve newly created form fields. (#20027) * Fixes an issue where rotating a page after deleting a note annotation could lead to an assertion failure. (#19853) * Fixes an issue where the line start and end of a polyline annotation didn’t honor a clear fill color. (#20097) ### Examples * Adds a PSPDFKit Catalog example illustrating how to add a Blend Mode menu item to the highlight annotation selection menu.

(#19817) * Fixes a crash within `PSPDFDocumentEditorViewController` that would happen when calling `-[PSPDFViewController reloadData]` after setting a new document with a lower page count than the current one. (#19839) * Fixes an issue where the annotation state of the `PSPDFAnnotationStateManager` was set to an empty string when no annotation tool was selected. (#19911) * Fixes an issue where the thumbnails view would automatically scroll for certain documents when the `stickyHeaderEnabled` property of `PSPDFThumbnailFlowLayout` was set to `YES`. (#19437) * Fixes the alignment of the indexing status cell in `PSPDFDocumentPickerController`. (#19673) ### PSPDFKit * Adds undo support for link annotations.

(#19661) * Improves results from `PSPDFLibrary` when the `PSPDFLibraryMatchExactPhrasesOnly` option is specified, and a tokenizer other than the default porter tokenizer is used. (#19685) * Prevents a potential multithreading violation when the sqlite backend is accessed while a low memory notification is broadcasted. (#19750) * Fixes an issue where the `PSPDFRenderDrawBlock` set using `-[PSPDFProcessorConfiguration drawOnAllCurrentPages:]` was overridden by the `PSPDFRenderDrawBlock` of a `PSPDFDocument`'s render options. (#19541) * Fixes an issue where an annotation would not be up-to-date when using the processor while using the external file annotation save mode. (#19498) * Fixes an issue where readonly checkboxes may not be rendered correctly. (#19506) * Fixes a crash that could occur when deleting annotations using the menu interface.

(#17062) ## 8.0.0 — 17 Oct 2018 _See the [announcement post](https://www.nutrient.io/blog/pspdfkit-ios-8-0/)._ This release features two new components - [Redaction](https://www.nutrient.io/sdk/solutions/redaction/) and [Comparison](https://www.nutrient.io/guides/ios/compare-documents.md). If you would like to add either to your license, [ping our sales team](https://www.nutrient.io/support/request) to receive a quote. Below is a summary of the API changes in this release. For a full list, with our suggested migration strategy for each API that has been changed or removed, please see the [migration guide](https://www.nutrient.io/guides/ios/migration-guides/pspdfkit-8-migration-guide.md). * API: Removes all deprecated API. For a full list with suggested migration paths, see the migration guide. (#16157) ### PSPDFKitUI * API: The flow for sharing documents has been revamped to allow the user to first decide what options to apply to the sharing documents and then sharing to a given destination; this change normalizes the sharing experience across PSPDFKit. Please refer the migration guide if you did anything related to sharing, such as overriding `PSPDFDocumentSharingViewController`, or using `PSPDFDocumentSharingCoordinator` or it's subclasses. (#16453) * API: Changes the return type of `PSPDFPageView`’s `showNoteControllerForAnnotation:animated:` from `PSPDFNoteAnnotationViewController` to `void` to make it clearer this can show custom UI. If you need the view controller being presented, use `pdfViewController:didShowController:options:animated:`.

(#15890) * API: Removes the `externalSignatureDelegate` property of `PSPDFSigner`. Use the `delegate` property instead, as it's intended to be more flexible. (#15853) * API: Removes the synchronous signing methods in `PSPDFSigner`. It's more preferred to use the ones that are based on setting a custom `dataSource` or `delegate`, as they offer more flexibility. (#15853) * API: Changes the parameters of the conversion functions between view and PDF coordinate spaces. (#15890) * Adds API support for resetting form fields to the `PSPDFFormParser`.

(#15479) ## 7.6.0 — 30 May 2018 _See the [announcement post](https://www.nutrient.io/blog/pspdfkit-ios-7-6/)._ In preparation for iOS 12, this version of PSPDFKit now drops support for iOS 9. It also requires and is built with Xcode 9.4 (9F1027a). The new Image Documents component, which enables you to keep `PSPDFImageDocument`s editable even after saving, requires an updated license. We prepared a [migration guide](https://www.nutrient.io/guides/ios/migration-guides/pspdfkit-7-6-migration-guide.md) to help you with some of the API changes in this version. ### PSPDFKitUI * Deprecates `PSPDFDrawLayer` related public APIs on `PSPDFDrawView`. (#14921) * Adds `-pdfViewController:shouldSaveDocument:withOptions:` and `-pdfViewController:didSaveDocument:error` to `PSPDFViewControllerDelegate`. (#14910) * Adds blend modes to the annotation inspector. The ink highlighter by default now uses a multiply blend mode for clear, black text. (#15080) * Adds customization options for `PSPDFNoteAnnotationViewController`. (#15305) * Improves comment author display in `PSPDFCommentCell` to accommodate longer author names. (#15065) * Improves layout of the buttons on `PSPDFSignatureViewController` by making them respect the safe area and dynamic type. (#15063) * Improves state restoration to restore and persist selected annotations. (#14935) * Improves support for Dynamic Type, particularly for larger accessibility sizes. (#14788) * Improves the layout of the stamps grid, to always look reasonably dense, while keeping the stamps big enough to read. (#13675) * Changes the default state of the Store Signature checkbox to be disabled to not store the created signature without users explicitly checking it. (#15250) * Makes selection experience more consistent across platforms. (#14729) * Makes the custom stamp option in the stamps UI more apparent. (#1824) * Moves 'Saved Annotations' to its own annotation toolbar item, as opposed to being a tab on the stamps UI. (#1824) * Setting the `doNotScroll` property on a form text field now works correctly. (#14926) * Sharing with `UIActivityViewController` now only includes the document, not the title as well. This fixes a Text File being created alongside the PDF when exporting files. (#12782) * The `userInterfaceViewMode` setting now defaults to `.automaticNoFirstLastPage`. (#15077) * The behavior of `scrollOnTapPageEndEnabled` has been changed to be enabled by default again and reacting immediately, without waiting for a potential double tap gesture. The edge span where taps are accepted `scrollOnTapPageEndMargin` has been reduced to 44 pixels. The default for `scrollOnTapPageEndAnimationEnabled` has been changed to NO. This allows fast tapping through a document. (#13098) * The home indicator on iPhone X is now automatically hidden when the HUD is not visible. (#15006) * `-[PSPDFTextSelectionView sortedGlyphs:]` now sorts the passed in glyphs in their reading order. (#15400) * `PSPDFConfiguration`'s `scrollOnTapPageEndMargin` and `scrollOnTapPageEndAnimationEnabled` is now honored when using `PSPDFPageTransitionCurl`. (#15333) * Fixes `-[PSPDFConfiguration shadowOpacity]` not being honored for configurations where the page transition was set to `PSPDFPageTransitionScrollPerSpread`. (#15369) * Fixes a crash in that could occur when selecting text if the initial selection did not contain any valid characters. (#15445) * Fixes a document's table of contents' colors not being shown correctly. (#15295) * Fixes a rare issue that could lead to a crash in `PSPDFResizableView` layout when rotating rapidly. (#15410) * Fixes an issue where comments would not scroll out from underneath the keyboard or toolbar on iOS 10 in `PSPDFNoteAnnotationViewController`. (#15415) * Fixes an issue where drawing a signature area was not possible when digitally signing a document via the `PSPDFPageView` signature API. (#14765) * Fixes an issue where embedded videos with autoplay enabled would start playing before their page was visible. (#14662) * Fixes an issue where the font size for a form element was calculated wrong. (#15274) * Fixes an issue where the printing UI wouldn't prevent interactions with the rest of the application, breaking the printing flow. (#10480) * Fixes issues with pages not being displayed in page curl mode. (#15280) * Fixes layout of saved annotations and stamps UI on iPhone X. (#1824) * Fixes text alignment for text field cells. (#15304) * Fixes the text insertion point not always staying in the visible area while writing comments on annotations. (#14201) ### PSPDFKit * The minimum deployment target is now iOS 10. Support for iOS 9 has been removed. (#14398) * API: The configuration builder blocks in `PSPDFBaseConfiguration` are now noescape for better Swift compatibility. (#15077) * API: The constants in `PSPDFAnnotationStyleManager` have been renamed and now better map to Swift. (#15077) * API: `PSPDFDocument.annotationsForPageAtIndex:type:` is now guaranteed to never return nil. (#15077) * Deprecates `PSPDFFileAnnotation`’s `appearanceName` in favor of `iconName`. (#15319) * Deprecates class-level methods on `PSPDFProcessor` and introduces new new instance-based API that allows for cancellation. (#10480) * Adds the ability to keep annotations on `PSPDFImageDocument`s editable even after saving. Requires the Image Documents feature to be enabled in your license. See https://www.nutrient.io/blog/image-documents/ for more information. (#14894) * Adds an external file source option when adding new pages to a document with the document editor. (V##248) * Adds blend modes to Annotations. This improves rendering for appearance steams with different blend modes. (#15080) * Adds the ability to define arbitrary patterns for new pages when editing a document. (#14951) * Adds the ability to embed files to `PSPDFFileAnnotation` using `-[PSPDFEmbeddedFile initWithFileURL:fileDescription:]`. See the new `AddFileAnnotationProgrammaticallyExample` and `AddFileAnnotationWithEmbeddedFile` in PSPDFKit Catalog. (#15210) * Improves JavaScript support, including form formatting, calculation, and validation. (#9501) * Improves XFDF output by omiting `opacity` if set to the default (1.0). (#15354) * Improves rendering behavior for stamp annotations. Stamps are keeping their aspect ratio on resizing now. Stamps created with PSPDFKit now always use the same rendering, no matter if they were just created or after being saved in the document. The subject of stamps is now always rendered in uppercase characters. Custom stamps are now sized-to-fit before adding them to the document. (#1824) * Adds annotation `name` to Instant JSON. Also renamed `pspdfkit/file` `name` to `filename` to prevent collisions. (#14856) * Adds better detection for standard stamp subjects for Instant JSON. (#14919) * Cancelling a `PSPDFRenderTask` now reduces further CPU usage more effectively. (#14218) * `PSPDFPageRenderer` is now deprecated and will be removed in a later update. (#15189) * Fixes a crash which occurred when manually searching a protected document. (#15177) * Fixes a potential deadlock situation during document cache invalidation. (#15259) * Fixes an issue where glyph frames were larger than expected due to unexpected values in their fonts. (#14169) * Fixes an issue where newly created note annotations would require two taps for deselection. (#15221) * Fixes security vulnerability CVE-2018-9127 in Botan, where wildcard certificates could be accepted for invalid hostnames. (#15374) * Fixes an issue where some action destinations may not work properly. (#14901) * Fixes a problem where editing some numeric form fields didn't show a completely numeric keyboard. (#15484) ### Instant * Adds support for Instant Layers: https://www.nutrient.io/blog/instant-layers/ (#13834) * Adds support for exporting and importing stamp annotations with images for Instant JSON. (#15296) * Improves error reporting regarding invalid JWTs. (Z#8755) * Deprecates all methods in `PSPDFInstantClientDelegate` in favor of renamed methods to improve API clarity and consistency. (#13834, #15464) * Deprecates `PSPDFInstantDocumentDescriptor`’s `updateAuthenticationToken:` and `downloadDocumentUsingAuthenticationToken:error:` in favor of the more specific `reauthenticateWithJWT:` and `downloadUsingJWT:error:`. (#13834) * Deprecates the notifications `PSPDFInstantDidUpdateAuthenticationTokenNotification`, `PSPDFInstantDidFailUpdatingAuthenticationTokenNotification`, and related `PSPDFInstantAuthenticationTokenKey` in favor of the notifications `PSPDFInstantDidReauthenticateNotification`, `PSPDFInstantDidFailReauthenticationNotification`, and the related `PSPDFInstantJWTKey`. (#13834) ### Examples * Adds a PSPDFKit Catalog example illustrating how to use a custom bookmark provider. (#15105) * Improves the Catalog's listing of examples. The Catalog now lists all the examples in the selected language. If an example is not available in the particular language selected, then the example in the other language is listed. (#15100) ## 7.5.2 — 4 May 2018 ### PSPDFKitUI * Fixes an issue where selection would work incorrectly if a page was cropped or rotated. (#15042) * Fixes the spread zoom not always being reset when scrolling back to a spread in the `.scrollPerSpread` `pageMode`. (#14825) ### PSPDFKit * Fixes an issue where glyph frames were incorrectly calculated when the page matrix is not identity. (#13668) ## 7.5.1 — 25 Apr 2018 ### PSPDFKitUI * Adds a `signer` subclassing hook to `PSPDFSignatureViewController`, enabling setting the certificate used for digital signing programmatically. This makes it possible to only allow the user to create a digital signature, instead of an ink signature. (#14846) * Fixes an issue where a crash could occur if `PSPDFNoteAnnotationViewController` changed size while it was presenting an action sheet. (#14742) * Fixes a keyboard avoidance offset issue during interactive keyboard dismissal. (Z#8690) * Fixes document pages not being selected when the thumbnail was tapped on the bottom half. (#14764) ### PSPDFKit * Improves compatibility of note annotations with certain 3rd-party viewers such as Apple Preview. (#14953) * Improves performance when annotations are loaded. (#14983) * Improves the logic when note icon indicators should be rendered. (#14961) * Saving image documents now keeps any additional extended attributes. (#14905) * Fixes a problem where the text in unsigned form field overlays may be cut off. (#14922) * Fixes an issue where images could be encoded in the PDF without optimization. (#14916) * Fixes an issue where recording couldn’t be started for an existing sound annotation. (#15010) ## 7.5.0 — 11 Apr 2018 ### PSPDFKitUI * API: Adds a `textView` parameter to `-[PSPDFNoteAnnotationViewController updateTextView]`. Customize the object passed to `updateTextView:` instead of using the `textView` property. (#5721) * API: Groups `PSPDFKitThumbnailViewFilter*` constants as extensible string enum. (#14571) * API: Removes the `tapGesture` property on `PSPDFNoteAnnotationViewController` and the class no longer conforms to `UIGestureRecognizerDelegate`. (#5721) * API: `PSPDFPageView` is no longer guaranteed to conform to `PSPDFNoteAnnotationViewControllerDelegate`. (#5721) * Deprecates `PSPDFNoteAnnotationViewController`’s `allowEditing`, `beginEditing`, `showCopyButton`, `deleteAnnotationActionTitle`, `deleteAnnotation:`, `deleteOrClearAnnotationWithoutConfirmation`, `textView`, and `borderColor`. (#5721) * Deprecates `shouldBeginEditModeWhenPresented` on `PSPDFNoteAnnotationViewController`, and `showNoteControllerForAnnotation:showKeyboard:animated:` in favor of `showNoteControllerForAnnotation:animated:` on `PSPDFPageView`, as choosing to show the keyboard is now decided based on heuristics, if the user might want to start editing. (#14205) * Adds UI to `PSPDFNoteAnnotationViewController` that enables the user to see existing reviews for a comment, add their own review status, or change their review status. (#14421) * Adds document type attribute to document load analytics event. (#14732) * Adds showing and adding annotation replies in `PSPDFNoteAnnotationViewController`. Replies will no longer be shown on the page. (#5721) * Adds support for `-[PSPDFConfiguration scrollOnTapPageEndEnabled]` in page curl layouts. (#13302) * Improves `PSPDFPageModeAutomatic` behavior in connection with `PSPDFPageTransitionScrollContinuous`. This now always prefers single pages to take better use of the available screen real estate. (#14822) * Improves the layout of the search view controller on devices with bottom safe area insets. (#12969) * Improves type safety by removing the `__kindof` type annotation from `-[PSPDFDrawView annotations]`, `-[PSPDFPageView passthroughViewsForPopoverController]`, and `-[PSPDFPageView selectedAnnotations]`. This only affects Objective-C. (#14490) * Changing page by tapping on page edges is now disabled by default. To enable this, change `PSPDFConfiguration.scrollOnTapPageEndEnabled` to `YES`. (#14418) * Ensures that `PSPDFAnalyticsEventNameAnnotationCreationModeExit` is always logged. (#14839) * Ensures that the optional analytics provider tracks log deletion for all cases. (#14817) * Removes ellipses in menu items (`UIMenuItem`) because there is no standard convention for this on iOS and space can be scarce. For example ‘Inspector…’ is now ‘Inspector’. (#14235) * Fixes an issue that could result in a crash when the size class changes while in a page curl layout. (#14555) * Fixes an issue that makes the page curl left or right align pages even though it is in single page mode. (#14555) * Fixes an issue that triggered a page change animation in page curl in some cases even though the page was already visible. (#14528) * Fixes an issue where `PSPDFPageView` would display a wrong page in rare occasions. (#14442) * Fixes an issue where annotations with the Invisible, Hidden, or NoView flags set could be tappable. (#14772) * Fixes an issue where pages were not animating into place when showing or hiding the inspector. (#13627) * Fixes an issue where paginated layouts would drift by a fraction of a point with every page if `PSPDFViewController` is set to a non-integer size in the direction of scrolling. (#14543) * Fixes annotations shown as overlays (notes) not respecting the Invisible, Hidden, and NoView flags. (#5721) ### PSPDFKit * API: Renames `PSPDFSignatureHashAlgorithmSHA386` to `PSPDFSignatureHashAlgorithmSHA384` which is actually the correct name. (#13932) * API: `tryLoadAnnotationsFromFileWithError:` has been removed from `PSPDFFileAnnotationProvider`. Use `loadAnnotationsWithError:` instead to customize annotation loading. (#14570) * API: Adds `isGenerated` to `PSPDFGlyph` to check if the glyph is an autogenerated filler. (#14606) * API: `PSPDFGlyph.indexOnPage` is not `-1` to indicate that it is a generated filler. Use `PSPDFGlyph.isGenerated` instead. `indexOnPage` can now be used to uniquely identify a glyph on a page, and is the index of the glyph in the `PSPDFTextParser.glyphs` array. (#14606) * Deprecates `PSPDFAnnotationOptionUserCreatedKey`. (#14669) * Deprecates `PSPDFTextBlock.glyphs`, `PSPDFWord.glyphs`, and `PSPDFSelectionState.selectedGlyphs` in favor of `NSRange`-based APIs. (#14606) * Adds `createdAt`, `updatedAt` and `creatorName` to Instant JSON. (#14443) * Adds `isReply` and `inReplyToAnnotation` properties on `PSPDFAnnotation`. (#5721) * Adds properties for author-specific state on `PSPDFNoteAnnotation`. (#5721) * Improves cleaning up resources in `PSPDFDocument`'s `dealloc`. (#14586) * Improves performance when examining document permission features. (#14747) * Improves text selection performance in documents with a lot of text. (#14516) * Filters out invalid characters from a page's text. (#14516) * Performance improvements for documents with many data sources. (#14651) * Removing an annotation with `removeAnnotations:options:` on `PSPDFAnnotationManager` or `PSPDFDocument` now also removes replies to that annotation. (#14385) * The relationship between `PSPDFXFDFAnnotationProvider` and `PSPDFFileAnnotationProvider` is now more explicit. If you use XFDF for form filling, you now need to keep around both providers. Furthermore, the annotation manager now only saves into the first annotation provider implementing the save method. Previously all were called, which could have led to incorrect results. (#14323) * Fixes a crash that could happen during application termination. (#14483) * Fixes a lock inversion when setting up the document providers. (#14525) * Fixes a potential crash when saving a document. (#14082) * Fixes a potential issue when removing annotations. (#14381) * Fixes an issue that prevented correct caching of rendered pages. (#14390) * Fixes an issue where `-[PSPDFTextParser textWithGlyphs:]` would exclude the last glyph. (#14636) * Fixes an issue where a flattened document shows a blank page in Preview. (#13708) * Fixes an issue where action destinations would not be found if sorted incorrectly. (#14412) * Fixes an issue where document checkpoints were not loaded for decoded document instances. (#14624) * Fixes an issue where image data wasn't properly removed after rewriting the PDF. (#14708) * Fixes an issue where searching for text in a document would return results with empty text blocks. (#14516) * Fixes an issue where some `PSPDFDocumentSecurityOptions` initializers would sometimes return nil. (#14646) * Fixes an issue where the documents `features` sometimes returned an incorrect value when called right after creating a `PSPDFDocument`. (#14574) * Fixes an issue where using a custom bookmark provider with readonly documents disabled adding and editing bookmarks. (#14574) * Fixes animated GIF images support in the gallery. (#13897) * Fixes document corruption issue when document has a header and is incrementally saved. (#14249) * Fixes pages not being centered when zooming is disabled in landscape. (#14091) ### Instant * Improves type safety by removing the `__kindof` type annotation from `-[PSPDFInstantDocumentDescriptor annotationWithIdentifier:forDocument:error:]`. This only affects Objective-C. (#14490) ### Examples * Adds PSPDFKit Catalog example illustrating how to rotate pages in 90 degree steps. (#14445) * Adds a PSPDFKit Catalog example illustrating how to add a custom filter by subclassing `PSPDFThumbnailViewController`. (#14380) * Fixes Catalog "XFDF Annotation Provider, Encrypted" example. (#13912) * Fixes an issue where the Document Editor icon was not visible in `NewPageFromDocumentExample.swift` and `ProgrammaticDocumentEditingExample.swift`. (#14641) ## 7.4.1 — 19 Mar 2018 ### PSPDFKitUI * Fixes an issue where enabling link annotation editing would not work. (#14477) * Fixes an issue where pages had a gap between them in page curl layout. (#13329) ### PSPDFKit * Adds `PSPDFAESCryptoDataSink`. (#13912) * Fixes an issue where the deletion of an annotation could not be undone properly. **Important:** Calling `removeAnnotations:options:` on a `PSPDFFileAnnotationProvider` no longer posts `PSPDFAnnotationChangedNotification`! Deleted annotations are still being returned from `dirtyAnnotations` until the next save — like before. They are, however, not returned from `annotationsForPageAtIndex:` anymore. This behavior is also far less surprising. (#14305) * Fixes a document corruption bug when the document has a header and is incrementally saved. (#14249) * Fixes Catalog "XFDF Annotation Provider, Encrypted" example. (#13912) * Fixes an animation glitch when rearrange pages with the document editor. (#14367) * Fixes an issue where `PSPDFTextParser.glyphs` could be incorrect for certain documents. (#10844) * Fixes an issue where dropdown arrow on combo boxes are not seen when box has a small width. (#14326) * Fixes an issue where dropdown arrows are still seen on combo boxes when document is flattened. (#9539) * Fixes issue where `pdfId` was required when importing a Instant JSON document. (#14494) * Fixes potential deadlocks during annotation rendering. (#14534) * Fixes an issue where opening large documents with marked content used very large amounts of memory. (#14415) * Fixes potential deadlocks when opening a lot of documents. (#14503) * Fixes an issue where `PSPDFFile.fileData` did not lazily memory map the file data when being called from user code. (#14539) ## 7.4.0 — 2 Mar 2018 _See the [announcement post](https://www.nutrient.io/blog/pspdfkit-ios-7-4/)._ ### PSPDFKitUI * API: Replaces `firstLineRect`, `lastLineRect`, and `innerRect` properties of `PSPDFTextSelectionView` with `rectForFirstBlock`, `rectForLastBlock`, and `selectionRects`. (#9677) * Adds a PSPDFKit Catalog example illustrating how to create a form programmatically. (#14215) * Adds a PSPDFKit Catalog example illustrating how to use the Instant JSON Annotation and Document APIs. (#14087) * Adds an overlay message shown when digitally signing a document without a form field. (#13583) * Adds support for selecting vertical text. (#322) * Improves compatibility with the React Native view component. (#14222) * Improves performance by only creating the text selection view's text parser when required. (#14291) * Improves performance when sharing file-based documents via the Open In activity. (#14011) * Improves visualization of thumbnails, especially when filtering for bookmarked or annotated pages. (#12512) * Improves text selection using `PSPDFTextSelectionView` by selecting text in distinct blocks. (#322, #9677) * Improves performance when editing free text annotations. (#13971) * Improves scrolling and zooming performance. (#13971) * Changes the inspector to use the annotation type as the title instead of Style. (#14057) * Tapping to select an annotation in multi-select mode now works again. (#11432) * Fixes a crash that happened when adding stamp annotations with 3rd party stylus support enabled. (#14086) * Fixes an issue where annotation notes were not editable on iPhone with iOS 9. (#14323) * Fixes an issue where bookmarks could be created but not saved into a document. (#9107) * Fixes an issue where content insets were not respected in searchable choice form elements while searching. (#13987) * Fixes an issue where switching between documents with different page bindings didn't update the scroll direction correctly. (#13849) ### PSPDFKit * API: `-[PSPDFContainerAnnotationProvider clearNeedsSaveFlag]` now **asserts that it is called inside a write block**! For more details, please refer to the documentation of `PSPDFContainerAnnotationProvider(SubclassingHooks)`. (#14181) * API: Certain types in Swift have been renamed to improve interoperability. (#10491) * API: `PSPDFDocumentSecurityOptions` initializers may return error instead of assert. (#10491) * Deprecates `encryptionAlgorithm` in `PSPDFPrivateKey`, in favor of `signatureEncryptionAlgorithm`, which is enum-typed. (#13940) * Adds `PSPDFDocumentFeatures` as a central place for checking the availability of various features. (#9107) * Adds a PSPDFKit Catalog example illustrating how to generate a PDF document on a mobile device without any server use. (#13776) * Adds a new protocol, PSPDFExternalSignature, that can be used to provide a digital signature for a document externally. (#13940) * Adds an example `UpdateConfigurationWhenRotatingExample.swift` for changing the configuration when rotating the device. (#13820) * Adds support for automatic access tracking for security scoped URLs. (#13863) * Adds the `shouldTrackDeletions` class property to `PSPDFContainerAnnotationProvider` to customize the effect of `removeAnnotations:options:` on `dirtyAnnotations`. See `PSPDFContainerAnnotationProvider.h` for more information. (#8839) * Adjusts the gap between two pages in continuous scroll mode. (#13877) * Changes the localized description of empty note annotations from Text to Note (localized). (#14057) * Improve error messages when digitally signing a document failed. (#13741) * Shows an error message when digitally signing failed instead of throwing an exception in some cases. (#13741) * PSPDFTextParser now respects reading order of text blocks defined in the PDF using Marked Content. (#9677, #322) * Fixes FTS5 search on SQLite versions >= 3.20.0. (#14036) * Fixes a deadlock when calling `removeAllAnnotationsWithOptions:` on an instance of `PSPDFContainerViewController` or a subclass and clarifies locking requirements. (#14178) * Fixes an assertion when a non-specified named action was deserialized via Instant JSON. (#13804) * Fixes an issue saving a document with invalid PDF syntax (empty dictionary key). (#14009) * Fixes an issue where `-[PSPDFAnnotation annotationFromInstantJSON:documentProvider:error:]` attached the annotation to the document. (#14140) * Fixes an issue where some annotations in a custom annotation provider were not rendered properly. (#12762) * Fixes an issue where some form fields with custom FQNs may not be signed correctly. (#14309) * Fixes an issue where the hash of two equal PSPDFAnnotation objects could be different.

(#8839, Z#5114) ### Instant * Adds `PSPDFInstantErrorInvalidURL` and stricter validation of the server URL to PSPDFInstantClient’s initializer. (#14158) * Improves recovery from network failures during sync by monitoring reachability of the Instant server. (#11901, Z#7385) ## 7.3.1 — 26 Jan 2018 ### PSPDFKitUI * Adds the ability to undo clear actions while editing free text annotations. (#13828) * Improves touch handling for the scrollable thumbnail bar mode for documents with only a few pages. (#13861) * Fixes a crash that occur if shake to undo is invoked during free text editing. (#13829) * Fixes an issue where presented annotations toolbar was not updated after changing controller's `PSPDFConfiguration`. (#13858) * Fixes an issue where tapping a free text annotation while selected doesn't start editing on 3D Touch compatible devices, or when using Apple Pencil. (#11424) * Fixes an issue where the displayed page labels were incorrect when switching layouts right after initialization. (#13824) * Fixes an issue which switching to the correct page when rotating from a double to a single page mode.

PSPDFKit has been split into two frameworks: `PSPDFKit.framework` for model and parser classes, and `PSPDFKitUI.framework` for UI functionality including view controllers. Below is a summary of the API changes in this release. For a full list, with our suggested migration strategy for each API that has been changed or removed, please see the [migration guide](https://www.nutrient.io/guides/ios/migration-guides/pspdfkit-7-migration-guide.md), which will also help with the framework split. * API: Removes all deprecated API. For a full list with suggested migration paths, see the migration guide. (#11669) ### PSPDFKitUI * API: Overhauls the view hierarchy for displaying documents. This involves many API changes. See the View Hierarchy section in the migration guide for much more detail. (#9773) * API: Replaces various API around signature saving with a more versatile `PSPDFSignatureSavingStrategy` used by `PSPDFSignatureViewController` and `PSPDFConfiguration` for managing saving signatures.

When moving from the old API, the order of the right bar button items will need to be reversed to match the UIKit convention. (#5830) * When tapping on a search result we now zoom to show the result in the document. This can be adjusted via `-[PSPDFConfiguration searchResultZoomScale]`. (#5758) * Replaces the `smartZoomEnabled` property of `PSPDFConfiguration` with a `doubleTapAction` property to be more flexible. (#4998) * The logic that finds custom search buttons is now smarter and will correctly anchor the search popover in more cases.

(#2739) * Adds a new `PSPDFLinkActionInlineBrowserLegacy` that forces the use of `PSPDFWebViewController` even on iOS 9 where the new Safari View Controller is available. This might be desirable in environments that need custom hooks on URLs which as of iOS 9 is not possible in `SFSafariViewController`. (#5744) * Better error handling when switching tokenizers in `PSPDFLibrary`. (#5771) * Searching now works better across new lines.

(Z#3202) * Fixes a regression where manually overriding the `rotation` of the `PSPDFPageInfo` object via `setRotation:forPage:` did not work in all cases. (#5659) * Fixes an issue where under certain rare cases around updating configuration while rotation is active we didn't show link borders when they should be visible. (#5818) * Works around an issue in Xcode 7.3 that broke the Visual Debugger. (rdar://25311044) * Works around a bug in `GLKView` on iOS 9 that could cause a crash under certain rare setups. (Z#3251) * Deprecates the `viewState` property and `setViewState:animated:` method on `PSPDFViewController` in favor of two new instance methods: `captureCurrentViewState` and `applyViewState:animateIfPossible:`, which are more explicit about how to use them and what to expect when doing so. ## 5.2.1 — 26 Feb 2016 * `PSPDFLibrary` now allows setting a custom tokenizer. (#5443) * Improved search results for `PSPDFLibraryMatchExactPhrasesOnlyKey` and `PSPDFLibraryMatchExactWordsOnlyKey`.

(#5542) * Be more selective about what annotation manager states we need to commit before a save event. (Z#3006) * Sound annotation control buttons now have a larger hit target. (Z#2984) * The new property `originalFile` on `PSPDFDocument` allows you to specify a source file if the PDF is the result of a conversion, so for actions such as Open In or Send via Email the original file can be selected. (#5531) * Empty input is now accepted on form fields with number formatting. (#4934) * Adds support for animated GIFs that have a variable frame rate. (#893) * Fixes an issue where zooming to a rect misses the target when the view controller is set to continuous vertical scrolling.

(#5170) * JavaScript format actions are now triggered when a signature is created on a form signature element. (#5184) * A long-press no longer calls `pdfViewController:didTapOnAnnotation:...` - only a regular tap does. (Z#2844) * After saving an annotation, the controller now automatically scrolls to the bottom. (#643) * When using `PSPDFPageTransitionScrollContinuous`, the view states that can be obtained from `PSPDFViewController` will now contain a viewport even when fully zoomed out. This preserves the scrolling position during rotation and makes it easier for you to capture and subsequently restore the exact reader’s location in a document. (#5052) * Fixes a potential race condition when rendering pages and calling methods from `PSPDFProcessor` at the same time while using a data provider. (Z#2768) * Fixes an rare issue when invalid points are sent via `touchesMoved:` to our draw view.

(#4968) ## 5.1.0 — 16 Dec 2015 _See the [announcement post](https://www.nutrient.io/blog/pspdfkit-ios-5-1/)._ PSPDFKit 5.1 focusses on improving the drawing experience, easier integration, better iOS 9 adaptivity and features a greatly improved night mode. * PSPDFKit is now compiled and requires Xcode 7.2. * We streamlined our manual integration process - take a look at our [new integration guide](https://www.nutrient.io/sdk/ios/getting-started.md) for details. * `PSPDFKit.framework` now includes its app symbols. This enables you to receive symbolicated crash logs from Apple after uploading your app to the App Store. * We now also ship SDK symbols to allow better crash identification. (Only available for license holders, see `PSPDFKit.framework.dSYM`). * We added pressure sensitivity to drawing and erasing. Natural lines can use pressure data from the Apple Pencil, 3D touch displays and some other supported styluses. The ink eraser radius can be adjusted based on the finger surface area or Apple Pencil altitude angle. (#4070, #1797) * Note: We now use a custom data structure to represent annotation points for certain annotation types. If you are accessing `pointArray`, `pointSequences`, `lines` or similar annotation properties, be sure to update your code to use `PSPDFDrawingPoint` from now on. * PSPDFKit now comes with a few built in appearance modes, that include an extended night mode. The modes can be set and customized via `PSPDFAppearanceModeManager`. `PSPDFBrightnessViewController` has also been extended with additional UI for this feature. (#3000, #4794) * API: Various smaller updates around toggling view controllers in `PSPDFAnnotationStateManager`. (#4642) * API: `editableAnnotationTypes` has been moved from `PSPDFDocument` to `PSPDFConfiguration` and is now a simple `NSSet`.

(#4503) * The annotation toolbar now has a new "Arrow" tool which is a variation of line with a predefined arrow head. (#4479) * Manually rotating pages is now possible again. See `PSCRotatePageExample`. (#4715) * The document view is now adaptive, even in situations where the keyboard is visible from another app in a multi-tasking environment. (#4714) * The document view now correctly adapts to keyboard frame size changes, mostly from 3rd-party keyboards. (#4714) * We added new items to the free text annotation `inputAssistantItem`, enabling you to toggle the free text accessory view visibility and adjust the font size even while the free text accessory view is hidden. (#4025) * The undo and redo buttons now get compacted into one button when the annotation toolbar space is limited. (#3994) * Various classes that should not be subclasses now declare this explicitly to prevent usage mistakes. (#4781) * Styluses without touch classification, e.g. Adonit styluses, are now using the eraser correctly. (#4658) * PSPDFKit Catalog samples have been reorganized and a few new ones have been added.

(#4100) * Various updates to the new render engine. ## 5.0.0 — 23 Oct 2015 _See the [announcement post](https://www.nutrient.io/blog/pspdfkit-ios-5-0/)._ PSPDFKit 5 is a major new version, introducing our own renderer and focusing on improving performance. It requires Xcode 7.1 and is compatible with iOS 8.0 - 9.1. This release is a huge usability improvement with Swift but also Objective-C, as we annotated all headers with generics. This release now shares our new core with our Android SDK to further improve quality and performance. * PSPDFKit now uses its own PDF renderer and no longer uses Apple's Core Graphics renderer, which means better performance, stability and quality. (#3737) * Undo and redo now remember individual lines drawn instead of the previous behavior where undo removed the whole annotation, once committed. (#2825) * The tabbed bar has been completely redesigned and now supports animations and reordering, not to mention it being much prettier. (#665) * View controllers are now presented using `UIPresentationController` and are much easier to handle and dismiss. (#3519) * We removed the `popoverController` and `halfModalController` properties, as these are now custom presentation styles. * Popovers are no longer dismissed on rotation. (#3519) * iOS 8 adaptivity is fully supported: view controllers swap between being popovers, half modal or full screen depending on context. (#3743) * A new presentation option has been added to prevent view controllers from adapting their presentation style: `PSPDFPresentationNonAdaptiveKey`. * The default presentation style has changed for `presentViewController:options:animated:sender:completion:` from `PSPDFViewController` and `PSPDFPresentationActions`. The default is now to use the presented view controller’s `modalPresentationStyle`, similar to the old `PSPDFPresentationStyleForceModal` style, which has been removed. * To restore the equivalent of PSPDFKit’s previous default behavior (using either a popover or full screen, depending on the space available), set the presented view controller’s `modalPresentationStyle` to `UIModalPresentationPopover`. * The annotation toolbar now automatically adapts its items depending on the available screen real estate. This change comes with a new API that allows setting multiple toolbar configurations amongst which the toolbar picks the optimal layout. (#3950) * The free text input accessory view has been updated to show popover pickers whenever possible, with a fallback to the half modal inspector, if vertical space is tight. (#3987) * Note: We noticed some input accessory view resizing issues on iPad Air 2 Simulator. We could not reproduce the same problems on actual devices. * We’re using `UIAlertController` and `UISearchController` everywhere, replacing the older deprecated API for further view controller unification. (#3381) * Automatic double page mode is smarter, comparing the aspect ratios of the view and the document and only showing two pages if they fit without too much shrinking. Automatic mode is now the default on iPhone too, but since two pages are only shown in large views the behavior will be similar. * By default, page thumbnails are now sized adaptively to comfortably fill the available space. * Instead of `CGPDFDataProvider` we now have a new `PSPDFDataProvider` protocol, which finally allows writing as well. (#3690) * `PSPDFAESCryptoDataProvider` has been updated to allow writing annotations back into the secure storage. * Safari view controller is used instead of `PSPDFWebViewController` on iOS 9. * `PSPDFScrobbleBar` has been renamed to `PSPDFScrubberBar` to better express its purpose. * Querying for the annotation author name has been moved to before the annotation toolbar is displayed. (#3544) * Annotation creation can now be prevented on select PDF pages by adding a boolean key to the page dictionary (see `allowAnnotationCreation` on `PSPDFPageInfo`). (#4308) * `PSPDFAnnotationStateManager` now supports multiple delegates and the delegate protocol gained some new methods. (#3607) * The color menu is now represented visually, and uses the style manager color presets. (#2802, #2890) * Switching between regular and callout styles for text annotations now produces better results and has been made easier with a redesigned UI. (#3664 and #3859) * The annotation stream now gets properly reset when an annotation is modified, preventing stale content from being rendered on screen. (#3817) * `PSPDFDocumentActionExecutor`’s `presentationController` has been renamed to `sourceViewController` to better describe its purpose and avoid confusion with `UIPresentationController`. * The `prefersStatusBarHidden` property in the `PSPDFStyleable` protocol has been renamed to `forcesStatusBarHidden` to be distinct from the closely related `UIViewController` method of the same name. * It is now possible to show color presents on `PSPDFAnnotationStyleViewController`, even if color and opacity settings are disabled. Color presets can still be hidden by adjusting `typesShowingColorPresets`. (#4108) * Accessibility and voice over support has been improved on some of our key UI elements. (#3834) * The author username is now requested earlier and managed via the new `PSPDFUsernameHelper` class. * The border radius of `PSPDFSearchHighlightView` is now dynamically calculated based on the current zoom level and can be configured via `cornerRadiusProportion`. * `PSPDFImageInfo` is now much more reliable and detects more image formats. * `PSPDFAction`s `nextAction` is now an array to correctly reflect the PDF spec, and the whole tree is iterated as required upon execution. * `PSPDFRenditionAction` now also exposes optional attached javascripts. * The hooks for `markedContentStack` and `shouldParseCharacter:` in the `PSPDFTextParser` have been removed since they were very rarely used but caused a noticeable slowdown for all text extraction. If there's demand, we'll look into ways to reintroduce a similar feature with less performance impact. * `prefersStatusBarHidden` in `PSPDFStyleable` has been renamed to `forcesStatusBarHidden` to not confuse this with properties that UIKit recently introduced. * Several annotation classes have new parent types to unify certain features, such as `PSPDFAssetAnnotation` and `PSPDFAbstractShapeAnnotation`. * Small UI updates across the board. (For example, dark colors are easier to see in menus.) * Various lesser-used API has been redesigned or removed for better clarity. ## 4.4.18 — 28 Oct 2015 * Due to a recent change in the iTunes Submission Process we've slightly altered our version scheme. (from ios-4.x.x to just 4.x.x) ## 4.4.17 — 15 Oct 2015 * Fixes an issue where the first thumbnail in scrollable thumbnail mode could be skipped under iOS 9. (#4270) * Removes our LZ4 dependency since Apple sometimes wrongly flagged that as private API. (Z#2097) If you're using `PSPDFLibrary` with glyph position saving, make sure to delete the cache files before updating. ## 4.4.16 — 6 Oct 2015 * Fixes an issue where some documents couldn't be parsed correctly to write annotations back in. (#4182) * Fixes an issue where document content was cut off with the toolbar enabled. (#4152) * Improves symbol visibility in new dynamic framework. (Z#1966) ## 4.4.15 — 25 Sep 2015 * Fixes an issue where the `PSPDFDocumentPickerController` wasn't correctly updated when a document was deleted. (Z#1882) * Prevents an exception from getting thrown while writing ink annotations into XFDF. (Z#1889) * Fixes an issue where executed JavaScript from forms could trigger an assertion. (#3872) ## 4.4.14 — 11 Sep 2015 This release will be one of our last v4 releases, while v5 for iOS 9/8 is steadily nearing completion with a huge list of updates/improvements. We backported the new bezier path calculation code, so ink annotations are quite a bit faster now. There's a lot more coming soon! * When invoking search, we now prioritize the current visible pages before searching the rest. Search results will show up significantly faster on complex documents. (Z#1829) * Fixes an issue where resetting choice form elements didn't always reset all properties. (Z#1813) * Fixes an issue when applying a `PSPDFRenderFiltersKey` on rotated documents. (#3892) * Fixes a rare floating point precision issue that could cause pages to show up distorted. (#3882) * Fixes an issue where rotation caused ill–positioned pages when switching from single–page to two–page layout. (#3878) ## 4.4.13 — 28 Aug 2015 * Improves rendering during annotation selection, decreasing the possibility of stale content. (#3488) * Improves behavior for the go to page dialog when invalid numbers are entered. (#3662) * Performance improvements for complex bezier path calculation, speeding up ink annotations. (#3778) * Fixes a rare exception when the page curl controller is used in unusual view controller configurations. (#3624) * Fixes a regression that was affecting performance in continuous scroll mode. (Z#1748) * Fixes a potential issue with rendering the color picker. (#3729) * Fixes an issue where `PSPDFViewState` could end up being nil for certain points between two pages. (#3782) * `-[PSPDFViewController setViewState:animated:]` supports animation for continuous scrolling and per–page scrolling again. Page curl mode has limited support: regardless of animation restoring the viewport is unsupported. (#3777) ## 4.4.12 — 10 Aug 2015 * Adds Slovenian translation. * Improves compatibility exporting file attachment in XFDF with certain less standard compliant readers. (Z#1610) * Fixes an issue when exporting XFDF polyline annotations with border style set to cloudy. (#3608) * Fixes a regression related to StrikeOut annotations. (Z#1642) * Fixes a crash when a file attachment annotation references a missing file which then is exported via XFDF. (#3620) ## 4.4.11 — 31 Jul 2015 * Adds Czech, Greek and Finnish translations and updates various other localization details. * API: The `rotationLock` has been removed. Subclass `PSPDFViewController` and override the rotation methods and/or implement `supportedInterfaceOrientationsForWindow:` to lock rotation. Since PSPDFKit doesn't own the application, yet this requires hooks to your app delegate, the previous implementation was flawed and subsequently removed. * Allow rendering the page to larger sizes when aspect ratio is preserved. (#3528) * Fixes an issue where links that also have QuadPoints defined might be offset. (#3331) * Fixes an issue related to bundle path resolution on relative linked files. (#3539) * Fixes an issue where `PSPDFCryptor` would report an error for files with a size that is dividable by 4096. (#3547) * Fixes a compatibility issue with the XFDF API version. (Z#1610) * Fixes an issue where the annotation toolbar's position couldn't always be set before it was initialized. (#3575) * Fixes an issue where the continuous scroll mode could result in a NaN exception under high load in split screen mode. (#3577) * Fixes a tiny memory leak when exporting XFDF files. ## 4.4.10 — 24 Jul 2015 * Improves document parsing for certain documents that are invalid according to the PDF 1.7 specification, yet work with Adobe Acrobat. (Z#1534) * Improves text placing logic for callout free text annotations. (#3476) * Improves compression for embedded images in stamps if they don't contain alpha data. (#3494) * Fixes an issue where the keyboard would not hide in all cases after dismissing the modal search controller. (#3449) * Fixes a race condition that could lead to a deadlock when forms are parsed and JavaScript processed concurrently. (Z#1546) * Fixes a rare assertion when the scrobble bar bins pages in landscape. (#3504) ## 4.4.9 — 17 Jul 2015 * Update OpenSSL to 1.0.2d. * API: Expose `PSPDFPageScrollViewController` and `PSPDFPagingScrollView`. (Z#1489) * Feature: Text selection is smarter on selecting words and better filters out commas or quotation marks. (#1954) * Performance: Greatly improved document parsing speed with a large set of annotations that need named destination resolving. (>10.000) (Z#1339) * Performance: Improvements for parsing forms on complex documents with more than 1000 pages. (Z#1422) * Improves parsing accuracy when page arrays contain invalid entries. (Z#1477) * Improves the UI/inspector flow when inserting free text annotations. (#3335) * Ensures that the inspector updates in all cases on alpha updates. (#3336) * Improves the HUD layout logic when changes are happening while the `PSPDFViewController` is off-screen. (#3361) * Improves calculation of the selection border for non-editable note annotations when zoomed in. (#3155) * Fixes issues with page centering while zooming. (#3340, #3419) * Fixes an issue with XFDF serialization of forms with parent/child relationships. (#3138) ## 4.4.8 — 6 Jul 2015 * Now using and requires Xcode 6.4 to build. Xcode 6.3.2 is unsupported but still works fine - however this might change in future updates. It's always a good idea to use the latest available tools. * Various performance improvements when parsing documents with a large amount of complex, nested form elements. (Z#1339) * Improves the thumbnail transition when multiple transitions are being executed concurrently. (#3248) * `PSPDFModel` can be serialized via `NSCoder` again. (Z#1394) * Ensures that highlight annotations don't have a border by default. (#3277) * Improves text field formatting to be more consistent with the way Acrobat handles formatting. (#2548) * Improves the combination of long press and `PSPDFLinkActionAlertView`. (#3289) * Improves `PSPDFHUDViewAnimationSlide` under iOS 8. (#2951) * Improves automatic thumbnail size calculation for certain edge cases in iOS 8. (#3045) * Decreases memory usage when trying to parse corrupted documents to ensure we are below certain memory limitations. (#3314) * Fixes an issue where customizable choice form elements sometimes didn't retain the correct selection. (#2919) * Fixes an issue where certain font styles in annotations could be lost when converting documents via `PSPDFProcessor`. (#3147) * Fixes an issue where invoking the image picker via javascript immediately dismissed the picker. (#3274) * Fixes a potential crash when `autodetectLinkTypes` is enabled and a phone number that is overlaid with custom annotations is detected. (Z#1402) * Fixes a potential crash related to a change in `NSDictionary` on iOS 9.0b2. * Fixes an issue where the email sheet sometimes is not presented if options are preselected. (#3137) ## 4.4.7 — 24 Jun 2015 WWDC week! We're hard at work to make sure PSPDFKit is a good citizen on iOS 9 and also grilled the UIKit engineers in San Francisco. This release features various first updates for the iOS 9.0b1 and Xcode 7. As usual, our strategy is to keep a stable PSPDFKit 4.4.x that works with SDK 8 (Xcode 6.3.2), supporting iOS 7, 8 and 9 (with some exceptions, like multitasking) - while at the same time we are also working on PSPDFKit 5, made for Xcode 7 and iOS 8+9. Expect PSPDFKit 5 some time in September before the iOS 9 GM. * Updates OpenSSL to 1.0.2c. (None of the security updates affects PSPDFKit, but it's a good habit to keep things up-to-date) * API: `pathShadowForView:` now returns an `UIBezierPath` object instead of a `CGPathRef` object. * API: `showsScrollIndicators` has been split into `showsHorizontalScrollIndicator` and `showsVerticalScrollIndicator` for a more fine-grained control. (#3191) * Improve custom font attribute support for outline. (#3111) * Exporting XFDF now writes the 'f' file tag.

(Z#1214) * Adds a workaround for an issue in Xamarin iOS 8.10 (https://bugzilla.xamarin.com/show_bug.cgi?id=30766) ## 4.4.5 — 31 May 2015 * Improves annotation border support. Add support for the legacy /Border definition, improves dash array writing and more. (#2953, #2964, #2982, #2987) * Improves menu positioning for line annotations, reduce likelihood of menu covering the resize knobs. (#2732) * Improves back animation when the thumbnail filter view is visible while the view controller is popped, working around an issue with UIKit's `topLayoutGuide`.

(#2986) * Works around an iOS 7 UIKit issue where the `contentInset` was not always correctly set in the outline view controller. (#2717) * Improves error handling around image extraction. (Z#1215) * Update simple font picker example and ensures the designated initializer for `PSPDFFontPickerViewController` is always called. (Z#1201) * Using `PSPDFProcessor` with the same input and output URL is documented as an unsupported operation. PSPDFKit will now detect this and return an error instead of potentially corrupting the output file. (#2985) * Workaround for an UIKit issue where `UIPrintInteractionController` could call into an released object. (rdar://20963891) * Files with multiple data sources can now also use the fallback annotation store. (#2804) * Fixes a rare crash when using the color picker from the half modal controller. (Z#1220) * Fixes an issue where the `UIActivityViewController` would not close automatically under iOS 7.

(Z#1192) * Fixes an issue where re-creating documents via `PSPDFProcessor` with embedded annotations that contain appearance streams could result in incomplete AP streams. (#2985) ## 4.4.4 — 26 May 2015 We're now using Xcode 6.3.2 to build PSPDFKit. * Greatly improves view state handling and view port stability, especially when rotating the device. (#2808, #2871, #2873) * Improves search bar handling for the outline view controller. (Z#1075) * Improves form tab order parsing and better deals with broken PDFs that have cyclic references. (#2903, #2817) * Adds a workaround for a tabbar gap issue on the half modal controller.

(Z#1176) * Improves color preset detection for annotations that are saved/loaded from the PDF directly. (#2915) * No longer creates highlight annotations with empty rects when using the highlight annotation tool without selecting text. (Z#1178) * Improves font size calculation in multi-line text fields. (#2921) * The `pdfViewController:didSelectAnnotations:onPageView:` delegate is now called after the `annotationSelectionView` has been configured. (Z#1166) * The Catalog contains new examples how to lock specific annotations (PSCLockedAnnotationsExample.m) and how to add new pages (PSCAddBlankPageExample.m) * Preserves custom protocol strings when unlocking a document with a password and improves documentation around this case.

(#2893) ## 4.4.3 — 15 May 2015 We're now using Xcode 6.3.2(gm seed) to build PSPDFKit. * API: `PSPDFTextSearch` has a new `cancelOperations:` parameter to control if previous operations should be cancelled. Since the previous behavior might be unexpected for some, we choose to not have a deprecated call. * API: Some refinements on calls in `PSPDFAnnotationStateManager`, removing a redundant "From:" from various methods. * Improve compatibility when the `PSPDFViewController` is embedded inside an `UITabBarController` with transparent bottom bar.

(#2485) ## 4.3.0 — 6 Mar 2015 _See the [announcement post](https://www.nutrient.io/blog/pspdfkit-ios-4-3/)._ In PSPDFKit 4.3 we focussed on improving our headers with additional documentation and nullability declarations and added many detail improvements touching all parts of the framework. On the feature side, we added a new global back/forward list that greatly improves navigation, especially for large documents. It is a highly recommended update. * We've started to annotate classes with Xcode 6.3's new `nullable` attributes, for better interoperability with Swift and more compile-time warnings in ObjC. This is still a work-in-progress and the API might change, as Xcode 6.3 is still in beta, however we also see it as a great improvement to documentation. * With `PSPDFBackForwardActionList` there is now a view controller-global back/forward list that allows a more efficient navigation in PDFs.

(Z#261) ## 4.2.2 — 11 Feb 2015 * Improves binning behavior in the scrobble bar for large documents. * Fixes an issue where the `PSPDFViewController` could be leaked when view controller containment was called with an incomplete call order. * Fixes a timing-related issue where searching via selected text could leave search results not highlighted initially. * Fixes an issue where embedded files were not always correctly previewed. * Fixes an issue related to document sharing. ## 4.2.1 — 10 Feb 2015 * Improves the way we store search text in `PSPDFDocumentPickerController`. * Improves tiling for the continuous scrolling mode. * Improves writing custom appearance streams for form fields when the value is encoded as UTF-16BE. * Improves the animation when adding/removing highlight annotations. * Improves audio session management; the code is now smarter when switching sessions is required to minimize background music stops. * Improves HUD showing/hiding logic when `scrollMode` is set to page curl. * Improves selection behavior for callout free text annotations. * API: Changes the options settings in `PSPDFDocumentInfoCoordinator` to strings to make them simpler to customize. * Fixes an issue that could cause some thumbnails to not load in the scrobble bar until the view was rotated under certain rare conditions. * Fixes an issue with missing symbols in the OpenSSL-free build. * Fixes an issue where some URL actions would not open the inline browser. * Fixes an issue where the `UIMenuController` would ignore taps when the menu was displayed and then `reloadData` called manually. * Works around an issue where the framework could trigger `objc_trap()` in rare occasions. (rdar://problem/19029811) ## 4.2.0 — 5 Feb 2015 _See the [announcement post](https://www.nutrient.io/blog/pspdfkit-ios-4-2/)._ We're proud to release [PSPDFKit 4.2](https://www.nutrient.io/blog/pspdfkit-ios-4-2/), which is the result of more than 2 months of hard work. Highlights are the new text editing toolbars, support for secure libraries via SQLCipher and a resizable inspector on iPhone. The gallery learned how to deal with web content and we now use the modern `WKWebView` internally whenever possible and is a lot faster for pages with many multimedia views. * Greatly improved handling for free text annotations with a new editing toolbar for both iPhone and iPad. * The half modal inspector on iPhone is now resizable and automatically adapts to the required content size. * Adds support for SQLCipher to have optionally encrypted search indexes with `PSPDFLibrary`. * The gallery can now deal with web content, replacing the `PSPDFWebAnnotationView`. * The gallery subsystem is now a lot more efficient, especially noticeable in cases where pages have > 10 different video/audio views (minor API changes due to the performance improvements) * `PSPDFWebViewController` now uses `WKWebView` by default, increasing browsing performance and scrolling speed. * The completion block for popover dismissal is now invoked after the popover is completely dismissed when animated is set to YES. * Security: Password protected documents now automatically disable the disk cache. * Natural drawings can now be exported/imported via XFDF. * Various improvements to annotation resizing. * Text field form elements that are configured as multi-line elements with auto-sized font are now better handled. * The Edit/Clear All buttons in the `PSPDFAnnotationTableViewController` are now hidden if there are no types set in `editableAnnotationTypes. * Sound annotations are now paused when the page is changed. * Sound annotations are now rendered into the thumbnail view. * The animation to toggle between thumbnails and the full page view now smoothly fades content and no longer blocks the UI while animating. * Performance improvements for documents with complex or deep form annotation trees. * Improves search preview to deal with content that has many newlines. * The editor for choice form fields no longer shows the form element title. * The `PSPDFOutlineViewController` now better deals with long page labels and will correctly calculate the height to show them completely. * Adds XFDF serialization/deserialization support for `PSPDFEmbeddedGoToAction`. * Updates the JotTouchSDK driver to 2.6.4 and fixes an issue with flipped touch points. * Ignore annotation types in the long tap menu that are set in `createAnnotationMenuGroups` but are not set in `editableAnnotationTypes`. * Various improvements and enhanced support for JavaScript actions and events. * Improves "Sign" arrow rendering for very small form elements. * Improves scrobble bar touch handling for certain cases when in double page mode. * Various cleanups and modernization for the `PSPDFCache` subsystem. * Rotating while drawing now correctly animates unsaved shapes as well. * Improved behavior of the "sticky header" thumbnail layout mode and greatly improves performance for large documents. * Closing a tab in `PSPDFTabbedViewController` now autosaves the document.

There is a new `PSPDFDocumentActionExecutor` and various coordinators (e.g. `PSPDFMailCoordinator`) which better replace this functionality + allow you to call such actions without a `PSPDFViewController` around. Settings (`applicationActivities`, `printSharingOptions`,...) have been moved to `PSPDFConfiguration`. * API: Removed `PSPDFMinimumSearchLength`. The default is now always one character to provide instant feedback and better support CJK languages. * API: `PSPDFHUDView` now exposes new insets for child views: `pageLabelInsets`, `documentLabelInsets`, `thumbnailBarInsets` and `scrobbleBarInsets`. This supersedes and replaces the more inflexible `pageLabelDistance` and `documentLabelDistance`. * API: Renamed `PSPDFSecurityAuditor` to `PSPDFApplicationPolicy`. * API: Moves `centerRenderStatusView` from `PSPDFPageView` to `renderStatusViewPosition` in `PSPDFConfiguration`. * API: `PSPDFFormSubmissionDelegate` now returns the `PSPDFFormSubmissionController` as first parameter instead of the PSPDFViewController. * API: `PSPDFThumbnailViewFilter` has been changed from an enum to strings, to make it both simpler to configure and easier to extend with custom filters. * API: `PSPDFThumbnailViewController` has been modernized; properties have been moved to either `PSPDFConfiguration` or simply edit the layout directly. * API: Exposes various new subclassing hooks. * Works around an UIKit issue where accessing `popoverPresentationController` could lead to a retain cycle.

(iOS 7.0 is still supported) If you use HockeyApp, Crashlytics or a similar crash reporting tool, we would love to hear from you. We're working hard to further reduce our already very low issue rate and appreciate your feedback. (support+crashreports@pspdfkit.com) PSPDFKit will now assert if you change annotation properties on threads other than the main thread. This behavior was unsupported before and was a cause for issues that were very hard to track down. Read more about the annotation object model at https://github.com/PSPDFKit/PSPDFKit-Demo/wiki/The-annotation-object-model. * Natural Drawing! You'll love this new default.

This allows secure storage of annotations. * The gallery has improved handling for fullscreen transition and properly tears down when the `PSPDFViewController` is popped while it is in full screen mode. * The gallery learned different cover modes, including a transparent one: https://github.com/PSPDFKit/PSPDFKit-Demo/wiki/adding-a-gallery-to-your-document * Multimedia links can now be activated via button and the gallery can be displayed as popover or modally: https://github.com/PSPDFKit/PSPDFKit-Demo/wiki/adding-a-gallery-to-your-document * The gallery will now correctly scale @2x images from remote servers. * The gallery now automatically pauses other instances when play is pressed. * The gallery now allows UIAppearance for blur and background colors. * The blur algorithm used for the gallery are now over 4x faster and also support live fullscreen blur. * The speech synthesizer (`PSPDFSpeechSynthesizer`) now auto-detects the best language by parsing the current document page. * Greatly improved AcroForm JavaScript validation support. * Improves support for custom controllers that don't define a preferred content size when used with `PSPDFContainerViewController`. * Empty ink signatures are no longer saved. * Add confirmation sheet for the "Clear All" button in the annotation table view controller. * It's now possible to correctly override `PSPDFAnnotationCell` from `PSPDFAnnotationTableViewController`. * The `PSPDFAnnotationTableViewController` now automatically reloads the content if the `visibleAnnotationTypes` property has been changed. * The `PSPDFLibrary` now optionally allows exact word matching with supplying the `PSPDFLibraryMatchExactWordsOnlyKey` parameter. * The XSigner attribute is now parsed and displayed as the signer name if no other name is defined in the digital signature. (PSPDFKit Complete feature) * Adds support for orphaned form elements that are not referenced in the AcroForm dictionary. * Reloading a document while the keyboard is up will no longer lead to the page animating back to center. * Add some additional safeguards/asserts and developer warnings that help to detect wrong use of certain methods. * Improve support for custom `PSPDFFlexibleAnnotationToolbar` configuration or when used manually without an `UINavigationController`. * PSPDFKit has been tested with Veracode (http://www.veracode.com/) and we've improved and hardened several code paths. * Add `PSPDFThumbnailFilterSegmentedControl` to enable UIAppearance rules on the thumbnail overview filter segment. * Add basic support for URL actions that are actually JavaScript actions. * Support loading images from asset catalogs via the pspdfkit:// image loading system. * The flexible annotation toolbar now better adapts to status bar changes on iOS 7. * Allow to manually force-load all annotations from the `PSPDFXFDFAnnotationProvider`. * Add support for embedded CMap streams for the text parsing engine. * API: The `PSPDFAction` objects and the `PSPDFPageInfo` objects are now immutable. * API: The toolbar now longer auto-hides when invoked via the context menu. This also removes the `hideAfterDrawingDidFinish` property. * API: Removed `setTextViewCustomizationBlock:` as it is inconsistent with what we do everywhere else in the framework. Use `overrideClass:withClass:` or the `pdfViewController:shouldShowController:embeddedInController:options:animated` delegate instead. To change the font, instead of `textViewFont`, simply change it in `updateTextView`. * API: The `bookmarkQueue` is now exposed via a property and not via an ivar in `PSPDFBookmarkParser`. * API: A few methods in the digital signature code have been renamed to be more clear about their intent. * API: Adds a new `pageTextFound` parameter to `didFinishSearch:` and now shows "Document has no content" if a document without text content is being searched. * API: `setGlobalBorderColor` on `PSPDFLinkAnnotationView` has been removed. The recommended API is to use `UIAppearance` on `borderColor` instead. * API: Remove explicit close button management inside `PSPDFContainerViewController` as the `PSPDFViewController` (via `PSPDFPresentationManager`) already provides this feature. * Fixes an issue where certain pre-encoded URLs with non-ascii characters could end up being encoded twice. * Fixes a potential stability issue in the accessibility support for line-based page reading. * Fixes an issue that could add overlay-based annotations to the wrong page when a redo action is invoked with soft-deleted annotations. * Fixes an issue related to text extraction font caching with different widths. * Fixes various rare issues when analyzing the document or writing annotations with partial UTF16-LE encoding, invalid document IDs or missing object references. * Fixes a rare crash issue related to missing languages and the `PSPDFSpeechSynthesizer`. ## 3.6.5 — 31 Mar 2014 * Some internal improvements to prepare for the upcoming stylus support. * Improves section styling of the annotation inspector under iOS 7. ## 3.6.4 — 30 Mar 2014 * The flexible annotation toolbar now automatically consolidates buttons if space becomes too short. * The image/video gallery now loops content by default, unless it's just a single item. (This is controllable by the new `loopEnabled` flag) * Improve documentation around gallery-usage and proper removal from full-screen. * The percent driven back animation of the inspector now animates the current selected cell out or restores it based on the animation progress. * Changes the HMAC format for the PSPDFCryptor from SHA1 to SHA256 to be more consistent with the RNCryptor data format. * The `moreBarButtonItem` action sheet is now dismissed when tapped on the button while it being open (instead of showing it again). * Enables the addition of global processor options via a new delegate to `PSPDFDocumentSharingViewController`. * `PSPDFProcessor` now has a new drawing hook (`PSPDFProcessorDrawRectBlock`) which can be used to watermark documents on exporting. * Fixes an issue that could prevent showing some search highlights if there are multiple on the same page. * Fixes a regression where sometimes the original view port wasn't correctly restored when the keyboard is dismissed after free text editing. ## 3.6.3 — 26 Mar 2014 * Improves placement precision of draft ink annotations when the device is rotated while in drawing mode. * Improves popover placement for the flexible annotation toolbar in vertical mode. * Multiple performance and memory improvements, especially for searching and scrolling large documents, and for usage on an iPhone 4. * Various cosmetic updates (improved thumbnail scroll bar, better support for iPhone 4 which doesn't support live-blur) * Improves search highlighting accuracy for certain document types. * Fixes an issue that could move the scroll view for keyboard events that were not inside the scroll view. * Small localization updates. ## 3.6.2 — 21 Mar 2014 * Improves appearance customization options for the new `PSPDFFlexibleAnnotationToolbar`. * The new `PSPDFFlexibleAnnotationToolbar` is easier to customize and also has an `additionalButtons` property to add custom actions. * Makes sure the `PSPDFFlexibleAnnotationToolbar` is always removed from the view hierarchy as the `PSPDFViewController` disappears. * The `PSPDFGallery` now better deals with custom quality properties for YouTube videos. * Ensures that the status bar doesn't change on iOS 7 with view controller based status bar appearance enabled when the `PSPDFStatusHUD` is displayed. * Improves the XFDF writer/parser to deal with more action types (`PSPDFRenditionAction`, `PSPDFRichMediaExecuteAction`, `PSPDFSubmitFormAction`, `PSPDFResetFormAction`, `PSPDFHideAction`). * Improves popover positioning logic, especially for the search popover. * Improves stability when using the new container annotation provider class. * API: Removes `aspectRatioEqual` and `aspectRatioVariance` from `PSPDFDocument`. Other performance improvements made this option no longer useful. * API: Clarifies usage of the `PSPDFGalleryViewController` by renaming the `allowFullscreen` property to `displayModeUserInteractionEnabled`. * Fixes a potential issue with an over-release of NSError when printing a single page with PSPDFKit Viewer. * Fixes a stability issue when serializing annotations for certain PDF AcroForm buttons with icons in the appearance characteristics dictionary. * Fixes an issue where changing the page via the annotation table view controller could end up on a page that wasn't correctly centered. * Fixes a small selection issue with handling multiple equal grouped annotations on the same page. ## 3.6.1 — 17 Mar 2014 * Before a document is saved, we now set the annotation state mode to nil, which commits any open annotations like inks. * Reverted the use of @import with modules. Apple's module feature seems to have issues with projects that also use C++. * Fixes an issue with saving annotations in certain PDFs with corrupted page IDs. ## 3.6.0 — 16 Mar 2014 _See the [announcement post](https://www.nutrient.io/blog/pspdfkit-ios-3-6/)._ We're proud to ship the next milestone of PSPDFKit. Version 3.6 features a completely new annotation toolbar, search within annotation text, note annotations that show up in the thumbnails and countless other improvements. This release has been fully tested with Xcode 5.1 and iOS 7.1. We now require at least Xcode 5.0.2 and SDK 7 to compile and have dropped support for Xcode 4.6 (Apple no longer accepts apps built with SDK 6/Xcode 4.6) Applications built with PSPDFKit will still run and work great under iOS 6. * Fully compatible and tested with iOS 7.1 and Xcode 5.1. * God dag! We've added Swedish to the list of presupplied localization files. * All-new flexible annotation toolbar (`PSPDFFlexibleAnnotationToolbar`) that can be dragged to be vertical or horizontal. See `PSPDFAnnotationToolbarType` in the `PSPDFAnnotationBarButtonItem` to optionally keep using the old annotation toolbar. * PSPDFKit Complete can now create digital signatures. This feature is still in beta - we need more documents to test all possible conditions. If you're having issues with this, please contact us so we can further increase the test coverage. * Text selection now supports text-to-speech on iOS 7+. See `PSPDFSpeechSynthesizer` for details and options to customize the language. * Forms on iPhone/iOS 7 now have an automatic zoom feature that makes it a lot easier to enter text. * Search now also includes annotation and form element contents. This is especially useful for note annotations and forms. (PSPDFKit Basic/Complete) * Search results are now hidden on page tap (unless that tap finds an action like selecting an annotation.) * Note annotations are now always rendered at the same size and also visible in the thumbnails. * PDF annotation writing will now be faster and produce a more compact trailer, reducing target file size. * Adds support for mailto: links with multiple email addresses (also for CC and BCC). * Saving will now use the correct z-index for annotations and forms in the same ordering as they are added. Saving changed objects will no longer change the z-ordering. * Simple JavaScript actions like printing, alert boxes or adding form values now work. If you have a use case for that, please contact us at support@pspdfkit.com. * The XFDF parser now parses basic rich text strings as used in Acrobat and keeps color and font informations. * Increases contrast for the selection color on form choice list-boxes. * `PSPDFTextSelectionView` now allows UIAppearance to customize `selectionColor` and `selectionAlpha`. * The `PSPDFActivityViewController` now checks if printing is allowed for the document before even showing the print option. * No longer ends the text view edit mode when zooming on iOS 7 (flat mode) and above. * File annotations are now evaluated lazily, which improves startup performance for documents with many such annotations. * Note annotations now also create popup annotation on PDF saving. These are optional but increase compatibility with certain less standard-compliant 3rd-party software. * The behavior of the pdfViewController:didTapOnPage:View:atPoint: has been updated when no `PSPDFPageView` was hit to return nil here, and coordinates relative to the current PSPDFViewController. * The `PSPDFThumbnailBar` has a new parameter to optionally enable the page labels: `showPageLabels` (defaults to NO). * Many improvements related to PDF AcroForm handling and input validation. * Calls to `didHidePageView:` and `didShowPageView:` of views with the `PSPDFAnnotationViewProtocol` are now properly balanced. * The text parser now has a more sophisticated text shadow/overlay detection, which improves search results by removing duplicated glyphs. * The gallery has a new mode that enables live-blur behind the content (see `blurEnabled` on `PSPDFGalleryViewController`). * Fixes an issue where the popover might open at an unexpected location when using the inline multimedia system with the popover:true parameter. * Font annotations are now rendered with their AP stream for greater document accuracy. * Annotations now support the additional action mouse up event. * Greatly improves speed for the XFDF image deserialization process. * API: PSPDFKit now requires the Accelerate.framework. If you're using the PSPDFKit.xcconfig file, you don't need to change anything. * API: Search related methods are now in the new `searchHighlightViewManager` property of `PSPDFViewController.` * API: The HUD and related views have been reorganized. You might have to update some calls (some views are now within `HUDView`) * API: `PSPDFProgressHUD` has been replaced with the all-new `PSPDFStatusHUD`, which features a modern iOS 7 design and an improved API. * API: `PSPDFDocument` should be treated as an immutable object (apart from settings). Thus, the `files` and `fileURL` properties have been made readonly, and `appendFile:` has been removed. Create a new document with the new files/data objects instead. Use the new helper `documentByAppendingObjects:` to create a modified document with a new file or data objects. * API: The `PSPDFAnnotationManager` now supports various protocol strings, thus the property `protocolString` has been renamed to `protocolStrings` and is now an NSArray that takes NSStrings. We've added `embed://` as a second, neutral protocol format. * API: The `textSearch` class has been moved from PSPDFDocument to PSPDFViewController. * API: `PSPDFNoteAnnotationViewFixedSize` has been removed. Notes are now drawn with a fixed size, however you can define the bounding box to whatever you like. We recommend using 32px, but this value is being ignored by both PSPDFKit and Adobe Acrobat. Other, less capable renderers like Apple Preview.app might use the value, so 32px is a good value - but also depends how large or small your document is. * API: The `PSPDFSignatureViewController` no longer dismisses itself. Dismiss the controller in the delegate callbacks. * API: Code and subclassing hooks that could be used to change the `PSPDFScrobbleBar` frame have been moved to `PSPDFHUDView`. * API: Removes various deprecated code. * Fixes an issue related to YouTube video parsing - now compatible with even more video subtypes. * Fixes a weird scrolling behavior for some form elements. * Fixes an issue where the free text tool wouldn't work if highlighting was selected before that. * Fixes an issue where PDF form values could become corrupted because of insufficient escaping in some PDF files. * Fixes an issue where drawings could be created on multiple pages if the page is changed while in drawing mode. * Fixes multiple issues related to forms on rotated pages. * Fixes an issue related to annotation fetching and the `pageRange` feature of `PSPDFDocument`. * Fixes multiple issues related to the ink eraser. ## 3.5.2 — 21 Feb 2014 * `PSPDFYouTubeAnnotationView` has been removed in favor of the newer `PSPDFGallery`. Te gallery is a much better user experience for embedding YouTube videos. * Adds a workaround to prevent unwanted `UIPopoverController` animations that might appear under certain conditions on iOS 7.0. * New property `highlightColor` on `PSPDFPageView` to control the color used for link/form touch feedback. * Improves reload behavior with an external animation block. * The play button for the `PSPDFGallery` is now always white and configurable via `UIAppearance`. * Improves fade animation of the page label under iOS 7, especially for the new blur-page label setting on iOS 7. * The `PSPDFDocumentPickerController` now uses a dynamic size when displayed as a popover. * Various smaller improvements related to the new sidebar example in PSPDFKit Catalog. * `defaultColorOptionsForAnnotationType` now returns an NSArray of string, color tuples. * Adds UIAppearance support for the default search view highlight color. * The note popover now will be dismissed on tap if the annotation state manager is used for highlight mode, just as it does when using the annotation toolbar. * The `allowsCopying` property in `PSPDFDocument` no longer controls if the "Copy" option for annotations is displayed. This property only controls text. * Makes sure that the ink width while drawing and rotating is always the correct one. * API: `padding` of `PSPDFViewController` is now of type `UIEdgeInsets` and also works with `PSPDFPageTransitionScrollContinuous`. * Stamps now more closely resemble the look of Adobe Acrobat. * Improves content type detection in the gallery. * Various localization improvements. * The XFDF parser can now write images within appearance streams to Adobe Acrobat. * Fixes an issue where the text rect could be CGRectZero if the `shouldSelectText:` delegate was not set. * Fixes an positioning issue related to custom scopes in `PSPDFSearchViewController`. * Fixes an issue where the `PSPDFMultiDocumentViewController` would not work as expected if the delegate was not set. * Fixes an issue where the `PSPDFMultiDocumentViewController` would only show the thumbnails for the first document. * Fixes a stability issue related to the "Clear All" feature and the XFDF annotation provider. ## 3.5.1 — 15 Feb 2014 * New property in the `PSPDFStyleManager` to control if changes to annotations should be saved as the new defaults: `shouldUpdateDefaultsForAnnotationChanges`. * Expose `cornerRadius` in `PSPDFResizableView` to customize the border appearance. * Behavior Change: Setting the `annotationSaveMode` to `PSPDFAnnotationSaveModeDisabled` will no longer disable annotation editing features. To disable annotation editing, set the `editableAnnotationTypes` property of the `PSPDFDocument` to nil instead. * Adds a new delegate "pdfDocument:provider:shouldSaveAnnotations:" to allow a more fine-grained control over the saving process. * No longer removes unknown views from `PSPDFPageView`. Use `prepareForReuse` to manually clean up if you subclass `PSPDFPageView`. * Improves compatibility with embedded PDF files. * Ensures that document metadata is preserved after writing annotations or forms. * Improves compatibility with annotation or form writing for certain less commonly used PDF subformats. * Improves several UI details for iOS 7 legacy mode. (`UIUseLegacyUI` or compiled with SDK 6. This mode is not recommended, but will work.) * The `PSPDFGallery` can now display YouTube videos. This will most likely replace `PSPDFYouTubeAnnotationView` in future versions. * The XFDF parser can now load images within appearance streams from Adobe Acrobat. * Fixes an issue on iOS 6 where the gradient background for the page position label could be too small. * Fixes a stability issue on iOS 6 related to `PSPDFBarButtonItem` tint color updating. * Fixes an issue that prevented to hide the thumbnail bar in `PSPDFThumbnailBarModeScrollable` unless `PSPDFHUDViewAnimationSlide` was also set. * Fixes some tiny memory leaks on error situations. * Fixes an issue related to re-using `PSPDFSearchViewController`. Thus only happened in custom code, as PSPDFKit recreates this controller as needed. * Fixes an issue where subclasses of `PSPDFFileAnnotationProvider` could encounter immutable objects where mutable objects were expected. * Fixes a stability issue related to autodetecting link types. * Fixes an issue related to exporting appearance streams via XFDF. * Fixes an issue where image stamp annotations in rotated documents could have an incorrect transform applied when saved via `PSPDFProcessor`. ## 3.5.0 — 10 Feb 2014 _See the [announcement post](https://www.nutrient.io/blog/pspdfkit-ios-3-5/)._ * API: The `PSPDFAnnotationToolbar` has been modularized and all state related code is now in `PSPDFAnnotationStateManager`, which is a property of `PSPDFViewController`. You might have to update your subclasses to reflect these changes. `PSPDFAnnotationStateManager` should now be used instead of a headless `PSPDFAnnotationToolbar` if you have your own toolbar. * New unified setBoundingBox:transform: method on `PSPDFAnnotation`. Adds a helper that transforms the font size on resizing. * The Inspector is now sticky and will update itself for the new annotation if one is tapped while the inspector is visible. This simplifies editing and saves some taps. * Various smaller animation tweaks. * The `PSPDFGallery` now shows the already fetched parts of a video in the progress bar. * Bookmarks now use the pageLabel, if one exists, instead of the logical page number. * Embedding YouTube objects now support parameters in the URLs. * Better handling of exporting annotations into rotated PDF pages via `PSPDFProcessor`. * Improves several cases where phone numbers were not correctly detected before. (`PSPDFTextCheckingTypePhoneNumber`) * Correctly displays border for forms that define the border color in the MK dictionary. * Adds initial support for text field form validation. (Currently, `AFNumber_Format` is supported.) * Adds limited support for drawing rich (formatted) free text annotations on iOS 7. Editing will convert them into plain text annotations. * Greatly improves XFDF support for complex PDF Forms, now better matches the output of Acrobat. * Fixes an issue that could reset the ink annotation width to 1. * Fixes a crash when processing certain sound annotations using PSPDFProcessor. * Fixes an issue where tapping into the page when the half modal controller on iPhone was visible could result in a different selected annotation than tapped. * Fixes an issue that didn't correctly update the thumbnails when bookmarks were added/removed while displaying the grid. * Fixes an issue that could show the signature selector controller when adding the first signature on iPhone only. * Fixes an issue where the document label could be visible even though documentLabelEnabled was set to NO. ## 3.4.6 — 1 Feb 2014 This patch release includes various form related improvements, especially hardware keyboard support and performance tweaks for very complex forms. * Tap-to-zoom now starts rendering the page instantly; this improves render performance quite a bit. * Visual improvements for the form choice view controller. * Multiline Form Text Fields are now vertically aligned to the top. * Editable choice form elements now show touch down feedback and keep the keyboard for easier switching on iPad. * Long-Pressing on form elements will no longer cancel the tap action. * Form elements can now be navigated with a hardware keyboard via the arrow keys and escape/space/enter. (iOS 7 only) * Form navigation with prev/next now includes choice form elements, and the value can be toggle with the space bar. * Ensures that stamps never draw text outside their boundaries. * Render/Update performance for pages with many annotations has been greatly improved. * When using the `PSPDFAnnotationTableViewController`, form elements are not only selected but also brought into edit mode. * Improves support for file:// links if linkAction is not set to PSPDFLinkActionInlineBrowser. * Tweaks link type autodetection to work better on certain types of documents. * Expose the completion handler for `UIActivityViewController` inside `PSPDFActivityBarButtonItem`. * API: Remove long press support for bar button items. This was only used for the bookmark button and already defaulted to NO. * `PSPDFPageView` now sends a `PSPDFPageViewSelectedAnnotationsDidChangeNotification` notification each time the `selectedAnnotations` property changes. * Erasing is now faster with custom annotation providers, as change notifications are now queued and sent on touch end events only. * Fixes an issue that could hide the outline bar button in cases where annotations were in the document but no outline. * Fixes a potential use-after-free when a form with a editable choice field was edited on iPhone and then dismissed via the input accessory view on iOS 7. * Fixes an issue where certain form checkboxes were not checked if appearance streams were missing from the PDF. * Fixes an issue where form buttons with named actions sometimes failed to change the page. * Fixes an issue where saving certain form objects could hide these form objects in Acrobat. * Fixes an issue where manual bookmark reordering wasn't saved in some situations. * Fixes a rare recursion issue on iOS 6 when using the old toggle-style for the viewMode bar button item. * Fixes an issue where the bookmark bar button not always reflected the actual bookmark state. * Fixes a potential over-release with certain rarely used CMaps definitions that include other CMaps. ## 3.4.5 — 24 Jan 2014 * Better handles resizing for rotated stamps. * The Open In... activity is now displayed for NSData-based documents. * Improve availability filtering for the `PSPDFOutlineBarButtonItem`, no longer presents an empty controller if no content is available. * Small localization updates. * Improve XFDF action writing for non-standard types like GoToR. * Improvements to word/new line detection in the text parser for certain documents. * Improves rendering performance, especially for more complex PDF forms. * Form updates are now more snappy and no longer animate. * Various smaller improvements for the inline web view. (`PSPDFWebAnnotationView`) * Fixes an issue where annotations could end up at a different location when rotated documents were re-saved using `PSPDFProcessor`. * Fixes an issue where `viewControllers` of the `PSPDFContainerViewController` could return nil. * Fixes an issue where annotations saved via `PSPDFProcessor` could end up on a different page. * Fixes an issue where the target page of a document/page action sometimes wasn't correctly saved when using the XFDF format. ## 3.4.4 — 22 Jan 2014 * Add support for Embedded PDF Files (see http://blogs.adobe.com/insidepdf/2010/11/pdf-file-attachments.html) * The `PSPDFGallery` now shows an AirPlay button if AirPlay sources are available. * Stamp annotations no longer have distorted text. * Update OpenSSL to OpenSSL 1.0.1f. * Forms: Checkboxes with the same name and parent form a mutually exclusive group. * `zoomToRect:page:animated:` now honors the `animated` option and compensates for the x/y origin depending on the scroll direction for `PSPDFPageTransitionScrollContinuous`. * Fixes an regression in the annotation toolbar related to tap handling. * Fixes an issue where the `PSPDFOutlineViewController` could display stale data if the outline is complex and documents are switched before the outline parsing operation was done. This basically only happened if the controller was displayed as a side-bar, not when in a popover or modal. ## 3.4.3 — 21 Jan 2014 * Code updated to be warning-free with iOS 7.1b4 and Xcode 5.1b4. * Extracted all possible `PSPDFMenuItem` identifiers to `PSPDFPageView`. * `PSPDFProcessor`'s `generatePDFFromURL:` and `generatePDFFromHTMLString:` methods now support embedding annotations if set via the options dictionary. * `PSPDFMultiDocumentViewController` no longer tries to persist NSData- or CGDataProviderRef-based documents. Only file-based documents are persisted between sessions. * Improves search animation for the `PSPDFOutlineViewController`. * Various small localization updates. * API: `PSPDFProcessor`'s generatePDFFromHTMLString: methods have gained a new error parameter. * API: `PSPDFAESDecryptor`'s init methods have gained a new error parameter. * Fixes a regression where two-finger-scrolling in highlight mode no longer worked. * Fixes a rare timing issue where a mutation error could be thrown if reloadData is called within page loading delegate methods. * Fixes an issue where exported annotation via the share sheet could end up on different pages if a document with multiple provider sources is used. ## 3.4.2 — 19 Jan 2014 * Improved defaults for the status bar and the activity controller. * The document and page label now use blur on iOS 7. * Full-page-ads with links now no longer highlight the whole page. * The bookmark activity now shows the current bookmarked state. * The thumbnail cells use the active tintColor on iOS 7 as their selection border color. * New property to control if the HUD should be visible on viewWillAppear. (`shouldShowHUDOnViewWillAppear:`) * Slightly darker default background for the `PSPDFViewController` on iOS 7. * Fixes an regression with the loupe view and UIInterfaceOrientationLandscapeLeft. * Fixes an issue where annotations could be missing when exporting single pages that are backed by XFDF via email. * Fixes an issue where the internal web browser wasn't correctly dismissed when an App Store link was detected. * Fixes an issue where the contentInset could become too large when using the `PSPDFStampViewController`. ## 3.4.1 — 18 Jan 2014 * Fixes an issue with UIActivityViewController on iOS 7.1b3. ## 3.4.0 — 18 Jan 2014 _See the [announcement post](https://www.nutrient.io/blog/pspdfkit-ios-3-4/)._ * The `PSPDFVideoAnnotationView` has been completely removed as the new `PSPDFGallery` takes over all of this functionality. PSPDFKit finally supports playback of multiple videos and/or audio tracks at the same time. (The total number of concurrent video streams is hardware dependent and is usually 4) * Ink annotations can now be merged via the multiselect tool. This will discard all different styles and use the style of the first object if used. * Various annotation changes and page updates are now animated (most visible when using undo/redo). * Various improvements and fixes for PDF Forms. * Improves the activity bar button item, actions will forward to the bar button items if possible. * The annotation toolbar will now attempt to merge highlights if they overlay each other and have the same color. * Improves hit testing for smaller annotation types like note annotations. * The `PSPDFPrintBarButtonItem` now uses the `PSPDFDocumentSharingViewController` to make it consistent with the Email and Open In action and thus has also new option parameters. (API-Change). This now allows printing the annotation summary. * The annotation summary now generates an attributed string when printing or sending via email. * Add `PSPDFAnnotationIgnoreNoteIndicatorIconKey` to optionally disable the note indicator rendering. * Improves support for links to different documents via URI action type. * Adding a signature will now make it smaller and more appropriate for large documents. * The `PSPDFSignatureSelectorViewController` is now stateful, has a minimum size and will show "No Signatures" if the last signature was deleted while being open. * The use of the outline in the search preview is now configurable via `useOutlineForPageNames` in the `PSPDFSearchViewController`. It defaults to YES. * New iPhone popover controller that better fits into iOS 7. * The annotation type image in the annotation table view is now colored in the same color as the annotation itself. * Adds a workaround for an issue where iOS would change the status bar when showing an UIAlertView without setting it back to the previous setting. * Exposes `filteredPagesForType:` to customize what the thumbnail controller displays, and increases the touch target of the thumbnail filter. * Fixes an issue when certain annotation types were manually overridden to be displayed as overlay, they could be initially visible until moved on page load. * Fixes an UI regression where the `PSPDFProgressHUD` would be rotated wrongly on device rotation. * Fixes an issue where YouTube videos were no longer being paused automatically in iOS 7 when in thumbnail mode. * Fixes a timing issue when multiple galleries were loaded at a page on the same time. * Fixes an issue in `PSPDFTabbedViewController` that could move pages off center when using iOS 7 when the HUD fades out. * Fixes an issue with embedding forms into documents with a invalid trailer ID. * Fixes an issue where dismissing the half-modal form choice picker could dismiss the current view controller on the iPhone. * Fixes an issue with extracting font glyph rect data, especially for CJK documents that use 'usecmap' to link to other CMaps. * Fixes a potential assertion in the text parser with certain malformed PDF documents that have invalid font descriptors. PSPDFKit will now try to extract as much as possible and not assert, even if the document is partly broken or contains invalid descriptors or font references. ## 3.3.5 — 9 Jan 2014 * The gallery now supports more options like autostart, cover views or control customizations. * Improved the `highlightedString` feature by narrowing down the target rect. Reduces the chance to extract text above/below the marked text. * The render activity view now has a slight delay and animates in and out, making it less disruptive. * Extends support for iOS 7 dynamic type to more controls and cells. * Localization has been streamlined and requires less entries. If you rely in a specific `identifier` for `PSPDFMenuItem` checks, remove the "..." from the strings. * The option view in `PSPDFNoteAnnotationViewController` now uses blur on iOS 7 instead of plain transparency. * Adds further workarounds for issues in `UITextView` on iOS 7 which improves caret scrolling and visibility when using external keyboards. * The "Clear All" action on `PSPDFAnnotationTableViewController` is now a single undo step instead of one per annotation. * Fixes an issue where the redo action of the `PSPDFAnnotationToolbar` would always prefer drawing redos, potentially preferring the wrong actions first. * Fixes an issue that blocked moving annotations if they are above a form field. * Fixes an issue that could select the wrong annotations when sending a single extracted page from a document via email. ## 3.3.4 — 7 Jan 2014 * The annotation table view has been redesigned and also shows the creation user and the last modification date, if available. * New property: `skipMenuForNoteAnnotationsOnIPad` to control how the note controller is displayed. * Update selection style for the saved annotation cells to better match the iOS 7 design. * Improves logic for popover resizing of the container controller. * Various tweaks to the stamp controller and the text stamp controller. Now adds default date stamps, automatically shows keyboard once the `PSPDFTextStampViewController` appears and more. * Various localization updates, including localization for stamps. * The `localizedDescription` for PDF Form Fields is now smarter and won't create strings like Button: Button. * The `PSPDFAnnotationToolbar` has a new `backButtonItem` hook to replace the default "Done" back button. * Some more icon tweaks: delete now better fits into the iOS 7 `UIMenuController` and sound now is a microphone instead of a note. * Fixes an issue with saving custom pspdfkit:// prefixed links via the XFDF provider. ## 3.3.3 — 6 Jan 2014 * Re-enables the Clear button in the new `PSPDFFreeTextAccessoryView` after text has been changed. * Don't show the ".pdf" file ending in the `PSPDFDocumentPickerController`. * The inspector now repositions itself if the annotation changes the `boundingBox`. * Saving annotations into the PDF has been optimized and creates a smaller PDF. * Form objects no longer are deletable when using the `PSPDFAnnotationTableViewController` but will be cleared instead. * API: Removed PSPDFInitialAnnotationLoadDelay. This is no longer a performance problem and has thus been removed and optimized. * Improves styling in `PSPDFWebViewController` for iOS 6 when the navigation bar style is dark. * The activity button in `PSPDFWebViewController` is now always enabled, not only after the page finished loading. * `PSPDFWebViewController` now offers to load the page in Google Chrome, if installed. * Fixes an UI issue where the document title label could be offset under iOS 7/iPhone if the HUD was hidden when a modal VC is invoked. * Fixes an issue that prevented forms from saving correctly when saved via the Send via Email/Open In feature from a readonly source. * Fixes multiple issues with building/preserving the appearance string for certain PDF form elements. ## 3.3.2 — 4 Jan 2014 * Adds new accessory view for free text annotations to quickly access the inspector. * The font size in `PSPDFNoteAnnotationViewController` now adapts to iOS 7 content size. * The gradient calculation used in `PSPDFNoteAnnotationViewController` now simply returns a default yellow if the base is white. * The delete note icon in `PSPDFNoteAnnotationViewController` is now dynamically enabled/disabled depending if there's text in the `UITextView`. * Improves the animation and various design details in `PSPDFSearchViewController`, especially on iOS 7. * Improves the annotation summary to now repeat type and description if that's the same. (Ink, Ink) * Various smaller design updates for the annotation inspector. * API Update: `generatePDFFromDocument:` now accepts `pageRanges` as NSArray, which enables easy re-ordering of document pages (compared to a single NSIndexSet) * Fixes an UI issue where the text view wouldn't properly adapt in `PSPDFNoteAnnotationViewController` on iPhone. * Fixes an UI issue where the "No Bookmarks" label could be not exactly centered on first load. * Fixes an issue where the annotation bar button item would be disabled with `PSPDFAnnotationSaveModeExternalFile`. * Fixes an issue where the document sharing controller would sometimes not extract pages out of the PDF if only a subset of the pages are selected. * Fixes an issue where wrong options could end up being used if `PSPDFDocumentSharingViewController` was preconfigured so it is invoked without showing the UI. ## 3.3.1 — 2 Jan 2014 * PSPDFKit now displays note indicators for annotations with note content. * Annotations that can't be erased are no longer hidden while in erase mode. * The view controller order in `PSPDFOutlineBarButtonItem` and in `PSPDFThumbnailViewController` has been changed - bookmark is now the last entry. * PSPDFSearchViewController now has support for custom scopes with a new optional delegate method. * On iOS 7 we now support `shouldAutomaticallyAdjustScrollViewInsets` with `PSPDFPageTransitionScrollContinuous` and `PSPDFScrollDirectionVertical`. * The scroll-to-top feature when the status bar is tapped no longer breaks when showing/hiding the thumbnail controller. * Fixes an issue with glyph position calculation for certain rotated documents that had a non-nil origin. * Fixes an issue that prevented linking the precompiled PSPDFKit.framework with Xcode 4.6. * Fixes a timing issue where the annotation menu wasn't always displayed wen selecting an annotation via the `PSPDFAnnotationTableViewController` on iPhone. * Fixes a small issue where the `PSPDFNoteAnnotationViewController` could fail to show the keyboard when presented manually with a certain timing. * Fixes an issue that could have kept a total 1-2 instances of `PSPDFPageView` around, even when the `PSPDFViewController` was deallocated. * Fixes a potential retain cycle in the `PSPDFDocumentSharingViewController` on iOS 7. ## 3.3.0 — 29 Dec 2013 _See the [announcement post](https://www.nutrient.io/blog/pspdfkit-ios-3-3/)._ Happy holidays! PSPDFKit now requires iOS 6+ and Xcode 5. Keep using PSPDFKit 3.2.x if you're still building with Xcode 4.6 or need to support iOS 5. Apple will enforce usage of Xcode 5 starting February 1st. (https://developer.apple.com/news/index.php?id=12172013a) Removing iOS 5 resulted in deleting almost 10.000 lines of code - which will give you a smaller, faster and more efficient binary. The binary is now again fully universal including armv7, armv7s, arm64, i386 and x86_64. The separate iOS 7 only (64 bit) library variant has been removed. PSPDFKit Complete now supports PDF form signature validation and thus links with OpenSSL. There is an optional build without OpenSSL that disables these cryptographic signature checks. * Localization! PSPDFKit now ships with English, Chinese, Korean, Japanese, French, Spanish, Russian, Italian, Danish, German, Portuguese and Brazilian Portuguese. * Adds preliminary compatibility with Xcode 5.1 and iOS 7.1b2. * Refreshed visuals for both iOS 6 and iOS 7. The icons are now much more polished and can be better customized. The remaining icons that were drawn in code are now all inside the PSPDFKit.bundle. * PSPDFKit Complete/Enterprise can now validate cryptographic signatures (unless you use the build without OpenSSL) * `PSPDFAESCryptoDataProvider` now supports the popular RNCryptor data format: https://github.com/rnapier/RNCryptor/wiki/Data-Format (It autodetects the legacy format and supports that as well) * Finally fully supports the new `UIViewControllerBasedStatusBarAppearance`. (we now support both modes in iOS 7) * The `PSPDFAnnotationToolbar` now displays the style picker for text markup annotations (highlights). * The `PSPDFGalleryViewController` now supports local/remote video and audio files next to images. * The internal `PSPDFWebViewController` now shows a progress bar, much like Safari on iOS 7. * Improves automatic font resizing for single line text field form entries. * Improved support for `additionalActions` and `nextAction` to add actions to all annotation types. * API Change: `PSPDFTextSelectionMenuActionWikipediaAsFallback` has been renamed to `PSPDFTextSelectionMenuActionWikipedia`. Since checking for a word in `UIReferenceLibraryViewController` can be unpredictably slow as of iOS 7.0.3, we had to remove this feature. `Define` will now always be displayed and you can optionally enable Wikipedia as well. The new default will omit Wikipedia by default. * Don't show the `PSPDFWebViewController` bottom toolbar on iPhone if there are no `availableActions` defined. * Allow detection for a PSPDFKit signature and blocks the "Copy" feature if detected. Will also be saved into the PDF as proprietary extension. * If there's no signature saved and customer signature is disabled, we'll show the new signature controller instantly. * Adds a new property: `shouldCacheThumbnails` to suppress thumbnail cache generation. * Adds a new property: `shouldHideHUDOnPageChange` to fine-tine when the HUD is hidden. * Highlight etc is no longer offered on text selection if the document can't be saved. * Improves Form Element description in the annotation table view. * Allow "Clear Field" for Choice Form Elements with editable text. * Improve support for hidden form elements or choices that are neither editable nor have options. * Add hitTestRectForPoint: on `PSPDFPageView` to allow customization of the rect that is used for tap hit testing to select annotations. * Make document parsing more robust to allow dealing with files that have incorrect XRef tables. * The text selection handles now have the proper hit test size when zoomed in - improves your ability to interact with other content. * YouTube: Add support for http://youtu.be short-form URLs for embedding. * The note icon name is now properly serialized when using the XFDF annotation provider. * The XFDF provider now only saves if an annotation is changed. Deserialized annotations are set to be not dirty by default now. * Annotation and outline classes have been optimized to require less memory and reuse more objects internally. * Lots of code cleaning, improved documentation and some reorganization. The binary is now smaller and compiles faster. * Moves document parsing to a background thread, improves initial startup time for complex, large documents. * GoToR actions with target named destinations are now supported. * FreeText annotations are now correctly rendered and displayed even when their bounding box is too small for the text. * Audio recordings can now be time limited and the default encoding/bitrate can be customized in `PSPDFAudioHelper`. * The default set of stamps is now localizable and localized by default. * The Edit button in the annotation table view controller and the bookmark controller is now only enabled if there is content, and edit mode is automatically disabled when there's no more content. * Improved touch handling when resizing/moving annotations. * Fixes an UX issue that wouldn't deselect the current toolbar state if a saved signature is added via the annotation toolbar while `customerSignatureFeatureEnabled` is disabled in the signature store. * Page scroll animations are reduced to allow faster navigation. * Annotation overlay views are now loaded and added to the view hierarchy as soon as the page is set up, removing the previous delay that was especially noticeable with note annotations. * No longer shows the bounding box when selecting/resizing line annotations. * The undo/redo stack is now consolidated - no more difference or disabled undo while in drawing mode. * Properly coordinate print controller popover to close when other popovers are activated. * Use blurry background for UIPopoverController in the stamp section. * The annotation creation menu now only shows the most important annotation types; customize via `createAnnotationMenuTypes` in the `PSPDFViewController`. * Removes the IDNSDK to get a smaller binary. * When saving text form elements, the AP stream is now included in the PDF. This fixes issues with Acrobat where the content would only be visible when the text field is active. * Fixes a rare crash in (poly)line point calculation if the points are on top of each other. * Fixes an edge case where the text field would loose focus after the note annotation controller has been dismissed because of tapping into another text field. * Fixes a regression where the selected annotation for multiple potentials was reversed. * Fixes an issue where annotations with appearance stream could be rendered at the wrong position and/or size. * Fixes an issue where annotations could be returned from the last page when forms are in the document, even if a different page was requested. * Fixes an issue with the label parser when encountering offset pages. * Fixes an issue where when trying to copy a webpage link in the internal web browser, the system could throw a `NSInvalidArgumentException` if the link was nil. ## 3.2.3 — 28 Nov 2013 * Improves custom text stamp creation layout and fixes an issue where the text wasn't always displayed within the table view. * Form text fields are now no longer clipped when the zoom scale is very low. * Border on a form is now only rendered when defined so in the dictionary for widget/form annotations. * Signatures now use `PSPDFAnnotationStringSignature` as style key, instead of the `PSPDFAnnotationStringInk` that was used before. * Improves support with Microsoft Outlook by making sure we always send the.pdf file ending when sharing via email. * Any open menus will now be dismissed before PSPDFKit is presenting a popover. This fixes a behavior change in iOS 7 where `UIMenuController` sometimes stayed visible. * Choice form elements now have a click-through-able popover and are highlighted when active. * Next/Prev now works across multiple pages and also includes choice form elements. * The form highlightColor is now a property on PSPDFFormElement and thus configurable. * Works around a bug in iOS 7 where the UITextView wouldn't properly scroll to a new line when entering text in a PDF Form. * The `PSPDFOutlineViewController` now shows the empty state if the document has no outline set but the controller is still displayed. * Improves compatibility with parsing invalid URLs in link actions - will correct more variants. * Fixes an issue where certain form choice elements with partial dictionaries could be incorrectly parsed/rendered. * Fixes an issue that could prevent form choice elements from being saved correctly back into the PDF. * Fixes a rare collection mutation regression when erase mode was active while annotation changes for visible inks were processed. * Fixes an issue where `allAnnotationsOfType:` sometimes could miss certain annotations when an internal save file was used. * Fixes an regression where `hasDirtyAnnotations` could report YES when we really don't have any unsaved changes. * Fixes some localization issues with line endings in the Inspector. ## 3.2.2 — 24 Nov 2013 * The gallery now allows image zooming when in full screen and requires less memory when loading remote images. * The gallery is now more customizable, allows custom background colors and recognizes @2x images when they are local. * The `PSPDFDocumentSharingViewController` will now use a temporary directory to save annotations into the PDF if it's in a non-writable location. * The password view now automatically shows the keyboard. * If annotations can't be embedded, the new annotation menu will not be displayed anymore (to be consistent with the `PSPDFAnnotationBarButtonItem`) * The runtime now better deals with multiple annotation subclasses that both change the behavior of a parent class. Use `overrideClass:withClass:` on `PSPDFDocument` to register such subclasses. * Set the default ink line width to 3, unless a default is already set. * Using undo/redo while in eraser mode will now also allow adding/removing of ink annotations. * The undo system will now commit expired actions that are coalesced. This fixes an issue where certain actions would appear undo-able quite late (e.g. first erase action) * If the named destination of a link can't be resolved we will ignore the action and no longer scroll to page 0. * Improve selection contrast in the `PSPDFAnnotationToolbar`. * The `PSPDFSearchResult` class is now immutable and has a new initializer for creation. * `PSPDFSearchViewController` now supports iOS 7 dynamic font size and allows a multi-line text preview. The new default are two lines instead of one. * Various warning/error messages are now printed with the code location instead of a generic PSPDFError trace. * Annotation management now uses equality checks instead of memory-based checks, this makes the code more robust when objects are recreated in the annotation providers. * Text field form elements now resize as we are typing and better render multi-lined text. * PDF Signature Form elements are now tappable and will offer to add a ink annotation as signature. * API change: Renamed `showNewSignatureMenuAtPoint:animated:` with `showNewSignatureMenuAtRect:animated:`. Use a rect with size zero to get the previous behavior. * API: Some subclassing hooks that have been declared but weren't called have been properly removed. * Undo/Redo is disabled by default on old devices to improve performance. (Notably, the iPad 1 with iOS 5.) * Improves error handling for corrupt or missing PDFs. * Using the HSV color picker while brightness is set all the way to 0% (black) will do the smart thing to switch to the pure color with 100% brightness. * Fixes an issue where ink annotations could change position for PDF documents with non-nil origin points. * Fixes an issue where some text in form elements could render incorrectly when the page was rotated. * Fixes a potential recursion when parsing malformed documents. * Fixes an issue where `annotationsFromDetectingLinkTypes:` could throw an exception if a page returns nil as body text. (e.g. corrupt or password protected files) * Fixes an issue where the gallery component could throw an `UIViewControllerHierarchyInconsistency` when used in combination with `PSPDFPageTransitionCurl`. * Fixes an issue where we incorrectly detected a regular password protection as custom encryption filter. ## 3.2.1 — 13 Nov 2013 * Improved a few cases where the `PSPDFDocumentSharingViewController` was displayed with practically no options to choose. * Improves the thumbnail <-> page(s) animation so it even looks great when the thumbnail button is toggled really fast. * The `PSPDFNoteAnnotationViewController` no longer shows the 'copy' button by default, the toolbar looked too cramped. * Fixes an issue with UID generation when the document isn't inside the app bundle. * Fixes an issue where larger XFDF ink annotations could degrade when being parsed. * Fixes an issue where the initial call for `annotationsForPage:` in the `PSPDFXFDFAnnotationProvider` could return an empty array. * Fixes an issue with UIKit legacy mode and the `PSPDFAnnoationToolbar` in certain setups. * Fixes an issue where 'Finish Recording' on sound annotations wouldn't work if the recording was still active but currently paused. * Fixes an rare issue with writing annotations if inline UTF-16 (the special Adobe flavor) is used within the `/Pages` root object. * Titanium: Exposes `printOptions`, `sendOptions` and `openInOptions` from the corresponding `PSPDF*BarButtonItems`. ## 3.2.0 — 10 Nov 2013 * Lots of improvements around sound annotations! Serialization, better selection, context menus, customization. * `PSPDFAnnotationTableViewController`: Dynamically calculate cell height and show multiple lines of description per cell. * YouTube and Web views now automatically reload themselves when a reachability change is detected. * Long-Pressing on text markup will now allow text selection and not select the markup (highlight) annotation. This enables sub-selection of text that is already selected in another way. * Greatly improves handling of (rotated) FreeText annotations and rotated pages. * The search bar is now attached to the top on iPhone, to better match iOS 7 style. * Rendered images are now more more likely to be cached to disk, resulting in less work overall. * Improves thumbnail scroll performance, especially on the iPad 1. * Improvements to the text parser, now can parse another category of documents that use Font Programs to define their glyphs. * Form Check Box Elements now render the AP stream by default and fall back to internal rendering if no stream was found. * Form background colors are now dynamically parsed and displayed instead of the default light blue. * Improves support for various Forms that define the form element across multiple objects. * Improves the touch-down-highlight for form elements. * Allows overriding of `PSPDFTextSelectionView`. * Improves text extraction for highlight annotations when there are multiple overlapping rects. * Fixes an issue where the text selection wasn't properly updated on rotation. * Fixes a potential deadlock when async saving was called manually while the view controller was popped from the screen which also invokes a save. * Fixes an issue where the tab controls of `PSPDFTabbedViewController` wouldn't respect the `minTabWidth` property. * Fixes an issue with rendering annotations with overlapping fill-areas in UIKit legacy mode. * Fixes an issue where certain `UIActionSheets` on iOS 6 could be mis-placed. * Fixes an issue with getting images for iOS 6 when the PSPDFKit.bundle is in a non-standard location. * Fixes a potential exception when a PDF contained an annotation with a malformed bounding box. * Fixes a potential exception when a free text annotation of size zero was created and subsequently edited. * Fixes an issue with saving annotation in certain documents that previously produced warnings. * Fixes a potential crash when loading annotations from the disk store while a save filter is active. * Fixes an issue where under rare conditions flattened notes could be rendered mirrored. * Fixes a rare condition where the cache could get into a state where it no longer pre-renders document pages. * Titanium: The plugin is now simply named `com.pspdfkit` (from `com.pspdfkit.source`) * Titanium: editableAnnotationTypes can now be set in `documentOptions`. ## 3.1.4 — 3 Nov 2013 * Improves rendering of line endings in the selected state. * Don't show an "external application" dialog if our own app responds to the URL scheme in question. * The PSPDFGallery can now better deal with a single image and will auto-generate the appropriate manifest if a PSPDFLinkAnnotation points to the image. * Allows overriding of PSPDFColorSelectionViewController from within the inspector. * Allows fine-tuning of the dictionary lookup via PSPDFTextSelectionView's new dictionaryHasDefinitionForTerm: method. * Enabling/Disabling the eraser feature no longer flickers the ink annotations. * The eraser now respects alpha settings of the ink annotations. * While erasing, Undo/Redo now work as expected. * Special-cased clearColor for the `fillColor` annotation property when using PSPDFStyleManager. (fill can't have alpha; so previously this would give you a black fill - now it's transparent) * Allow parsing for less common color definitions in appearance strings (k and g) * Forms: Don't draw background when we have an AP stream for form buttons. * Forms: Buttons that define an AP-Stream no longer also have a blue background. * Forms: Buttons(Check boxes, radio buttons) now show a touch-down state when tapping them. * Forms: No longer flickers when the element is deselected. * Fixes a potential crash in the selection view when we select a free text annotation with zero width. * Fixes an infinite loop when searching certain characters. ## 3.1.3 — 24 Oct 2013 * PSPDFKit now requires the CoreTelephony.framework (this will be added automatically if you use the PSPDFKit.xcconfig file) * The `autodetectTextLinkTypes` feature is now faster and will detect more types of phone numbers and URLs, including those that contain spaces/newlines between them. * Pressing the delete icon in the note annotation controller will only clear the note, except for note annotations where it will delete the whole annotation. * Adds a versioning system for PSPDFKit.bundle. Make sure you always use the bundle we ship with PSPDFKit. * Adds a boxRect:forPage:error: method to PSPDFDocument to easily get a different box rect for the defined page. * Gallery now supports animated GIFs and downloads images even when the app is in background. * Improves default header color for the mail view controller. * Fixes an issue where the bounding box for FreeText annotation could be too long when they are edited while zoomed in on iOS 7. * Fixes an issue where "Inspector..." was displayed for non-editable annotation types. * Fixes an issue where "Clear All" deleted all annotations, even those not displayed in the annotation table view. * Fixes an issue where flattened note annotations would sometimes be drawn rotated on rotated documents. * Fixes an issue where Free Text annotations added from the toolbar could end up being rotated on rotated documents. * Fixes a very rare over-release of a PSPDFPageView object when lots of PSPDFViewControllers are rapidly created/destroyed. (you should always reuse this heavyweight object) ## 3.1.2 — 21 Oct 2013 * Faster scrolling, new default page rendering strategy: `PSPDFPageRenderingModeThumbnailIfInMemoryThenFullPage` * Improves text selection drawing and text selection menu placing. The few cases where the menu could overlap the selection have been fixed. * Add more sophisticated warnings if the PSPDFKit.bundle is missing. * PSPDFViewController will now auto-save annotations when the view is dismissed while contained in a child view controller. * Add `verticalTextAlignment` to `PSPDFFreeTextAnnotation`. This is not defined in the PDF spec; so it will be a code-only option for now. PSPDFKit will save this into the PDF as a proprietary extension. * Fixes an issue with single page documents, forced two-page-mode and pageCurl. * Fixes an issue where under certain conditions the navigationBar was not displayed initially. ## 3.1.1 — 19 Oct 2013 * Restores compatibility when compiling with Xcode 4.6. * Various smaller improvements to the new image gallery. * Various smaller performance improvements, moved some more work off the main thread. * API cleanup for PSPDFDocumentProvider. * No longer blocks the UI when annotations are still loading during a touchDown event. * Fixes an UX issue where dismissing the activity popover in the web view controller via a touch on the dimming view sometimes required a second touch on the action button to re-show. * Fixes an issue when adding annotation views for invalid rects. ## 3.1.0 — 18 Oct 2013 * Brand-new image gallery (define a region in the pdf to be covered by a smooth gallery). Allows configuration via inline-pdf or external JSON. * Use menu-based annotation manipulation for text markup annotations. * The way how the document UID is generated has been changed. Previously, for files it used the full app path. However since the app UID could change after an upgrade, we had to change this behavior. This is only important if you used bookmarks or allowed annotations saving into the internal storage - not for embedded annotation data. Set the global variable `PSPDFUseLegacyUIDGenerationMethod` to YES to continue using the old path. Those files are in Library/PrivateDocuments. You might want to write a custom migration step to rename the custom data paths from the old UID to the new UID system. The `PSPDFUseLegacyUIDGenerationMethod` can be changed at any time to switch between old and new UID (generate a new PSPDFDocument instance to force UID regeneration). * The file-based annotation backing store by default no longer saves link annotations but instead merges the saved annotations and the links from the file. This improves performance for PDFs that have lots of internal links (our current way of saving starts to get slow once there are more than 10.000 objects). In most cases, you don't need to care and your save file will be migrated automatically. If you rely on custom link annotations being saved/deleted, you need to set the new `saveableTypes` property of the fileAnnotationProvider back to the old default `PSPDFAnnotationTypeAll`. * The undo/redo buttons are now updated immediately after adding annotations. * The interactivePopGesture (new on iOS 7) is now disabled while we're drawing to prevent accidental usage. * The PSPDFViewController will now properly clean up state from the annotation creation when dropped from user code while the toolbar is in drawing mode. * The outline controller now properly shows page destinations above page 10.000. * Hides a harmless log warning when PSPDFKit tried to render an annotation with an empty width/height. * When undo is disabled, the undo/redo buttons are now properly hidden when leaving the drawing mode. * No longer draws the arrow when flattening choice form elements. * Restores sound annotations that were added via the pspdfkit:// protocol. * Improves compatibility with UIViewControllerBasedStatusBarAppearance. (ongoing project, still not recommended.) * Greatly improves scrolling performance with large outline tables. * Fixes placement of the search bar in the outline controller. * Fixes a crash when pressing undo while adding free text annotations. * Fixes a call to a not implemented method in the file annotation provider when manually replacing annotations. * Fixes a crash in arm64 when parsing certain malformed PDF documents. * Fixes an issue where the password view wasn't correctly updated when the document was changed while it was displayed. * Fixes an issue where one could get stuck in the eraser mode when choosing it from the toolbar when that one was displayed via the long-press annotation menu. * Fixes a timing issue where the text parsing could crash in rare cases. * Fixes an off-by-one error that could cut off long lists of ink points when parsing XFDF files. ## 3.0.11 — 10 Oct 2013 * Fixes another issue related to UISearchDisplayController and iOS 6/7. ## 3.0.10 — 10 Oct 2013 * The search controller header is now sticky on iPhone (especially improves display on iOS 7) * Greatly improves text selection performance when a large number of glyphs is selected. * Improves eraser mode - faster, and no longer changes the view port when enabling/disabling. * Adds a new convenience method (sortedGlyphs:) when glyphs are manually selected in PSPDFTextSelectionView. * Improve various details in the XFDF writer. * Allow pspdfkit:// URLs within the PSPDFXFDFAnnotationProvider. * Remove confusing search controller animation when it's first presented on iOS 7. * Improves outline searching on iOS 7 / iPhone. * Various other smaller tweaks related to iOS 7. * Don't show the PSPDFDocumentSharingViewController if there are no options available. * Ensure the annotation style picker closes when the annotation mode changes. * Improves type detection when pspdfkit:// links are used within URLs that have query parameters. * Adds a workaround for documents with invalid /Pages structure which previously prevented annotation saving. * Add missing localization for "Choose Fill Color". * The text selection end handle is now prioritized, makes it easier to extend selection for small text. * Fixes an issue where changing the position of a note annotation could fail on the first try. * Fixes an issue with calling the didCreateDocumentProviderBlock for multiple files. * Fixes a 20-pixel offset in the annotation inspector on iPhone/iOS 7. * Fixes updating the thumbnail button state. * Fixes an issue when showing the annotation toolbar from the bottom. * Fixes an issue where popovers could have a width/height of 0 when presented from a bottom toolbar on iOS 7. * Fixes a crash on iOS 5 related to the font picker, rotation and early dismissal. ## 3.0.9 — 4 Oct 2013 * Greatly improves compatibility with text extraction/search, especially for Chinese/Japanese/Korean fonts. * The autosave feature of the PSPDFViewController can now be controller via the 'autosaveEnabled' property. Defaults to YES. * Improves the transition between stamps and saved annotations for iOS 7 legacy mode. * Hide the downloadable fonts section if there are no fonts to download. * Disables an unwanted implicit animation in the annotation style inspector for iOS 7 legacy mode. * The "Paste" menu is now more clever and will check if creating the new annotations is allowed before it's displayed instead of failing silently. * Re-enables search for the outline controller on iOS 7. * Fixes an issue in the PSPDFMultiDocumentViewController when the array of documents was set to nil. * Fixes a potential crash when parsing invalid PDFs with AcroForm data. ## 3.0.8 — 2 Oct 2013 * Use a background task to save annotations when the application enters the background to make sure it finishes before the app gets killed. * Thumbnail page label is now re-enabled by default. (Control this via subclassing PSPDFThumbnailGridViewCell and setting the pageLabelEnabled property.) * Ensure the status bar is visible if it was originally visible when showing the note view controller on iPhone. * Improves various details for the note controller, bookmark controller, annotation controller and outline controller related to iOS 7 tinting. * Fixes an issue where saved note annotations sometimes were not correctly removed from the page view until the page was changed. * Fixes an issue where ink annotations could end up on the wrong page when using multiple document providers. * Fixes an issue that could prevent the grouping menu from appear in the annotation toolbar. * Updated some graphics in the PSPDFKit.bundle. ## 3.0.7 — 1 Oct 2013 * Improves compatibility with resolving named actions. * Ensures that the PDF outline is hidden if no page action targets could be resolved. * Reenable undo/redo by default. * Fixes a tiny memory leak. ## 3.0.6 — 1 Oct 2013 * Always updates bar button items on a document change. Fixes conditions where a button could be in an disabled state if not used in the main toolbar. * The status bar state captured at viewWillAppear is now only restored when the PSPDFVC is popped from the stack, not on every disappear. * Makes it easier to disable undo/redo. (new undoEnabled property on PSPDFDocument) * Improves error return code when saving annotations. * Fixes an issue where unsaved annotations could be lost during an low memory event when using the tabbed view controller. * Fixes a potential non-main-thread call while preparing for saving. * Fixes an issue with saving certain documents. ## 3.0.5 — 30 Sep 2013 * Font picker now is searchable and shows downloadable fonts. * The eraser UI properties can now be changed via UIAppearance proxies. * The form text field update logic is now more clever and won't change form objects if they are only tapped. * Improves styling of the mail sharing view controller on iOS 7. * Improves interoperability with Objective-C++. * Improves support for a white global tintColor on iOS 7.

Important! Currently PSPDFKit 3 requires that you set the key UIViewControllerBasedStatusBarAppearance to false in your project Info.plist file. We're working on supporting view controller based status bar appearance in a future update. Note: Several methods and constants have been updated and renamed to make the API cleaner. Read the [PSPDFKit 3.0 Migration Guide](https://github.com/PSPDFKit/PSPDFKit-Demo/wiki/PSPDFKit-3.0-Migration-Guide) if you're updating from version 2. Important: PSPDFKit 3 requires a serial number and will run in demo-mode by default. Visit https://my.pspdfkit.com to register your app bundle ID and get the serial. If you are a PSPDFKit 2 customer with a license that includes a free PSPDFKit 3 update, please contact support@pspdfkit.com with your PET* purchase number to get an invite. PSPDFKit 3 still supports iOS5, however we plan to drop support for it later this year. We already see less than 5% usage and expect this number to drop further in the future. With the release of PSPDFKit 3 we will focus development on this version and won't be able to offer support for version 2 anymore. Most customers who bought PSPDFKit after January 14th are eligible for a free update, if your update window is still open (6 months for Binary/Viewer, 12 months for Source/Enterprise) Contact us with your PET* purchase number (or invoice ID) for details on your status. ## 2.14.22 — 1 Oct 2013 * Fixes a crash when parsing certain documents with invalid font references. ## 2.14.21 — 12 Sep 2013 * Adds a workaround for a bug where thumbnail icons could disappear in iOS 7 legacy mode. * Ensures we always have a document UID set.

Line ending size has also been increased to better match Adobe Acrobat. (Thanks Tony Tomc!) * The PSPDFRenderStatusView is now a public class which can be used to customize the loading spinner displayed while rendering a PDF page. * Annotation resizing when zoomed in deeply has been greatly improved. * Further improves text parsing speed and word boundary detection. * Fixes an issue where in some cases annotation resizing could fail when changed via the menubar directly before the resize action. * Fixes a potential one-pixel rendering bug that could result in thumbnails for certain aspect ratio combinations having white lines at one end of the image. * Fixes an issue that would sometimes mark certain PDF links to localhost as "webview" when they in fact only are regular links. ## 2.14.5 — 27 May 2013 * PSPDFWebViewController will now use UIActivityViewController on iOS6 by default. * Support new "loop" option for video annotations. * Use images for the text alignment setting. * Improve HSV color picker brightness style. * Improve word detection for PDF types that already have spaces added and also improves word-break-behavior for ligatures. * PSPDFKit will now attempt to render even unknown annotation as long as they define an appearance stream. * Improve search and glyph extraction performance. * Fixes an issue that could result in the HUD being in a hidden state after adding line/ellipse annotations from the annotation menu while the annotation toolbar is visible. * Fixes a potential crash when the PSPDFDocument was deallocated early. * Fixes a rare crash with a malformed PDF in the text extractor. ## 2.14.4 — 23 May 2013 * The annotation resize control now shows guides for aspect ratio and square resizing. * The outline controller now shows the target page and properly highlights the outline button. * Improves rendering of rotated stamps/images on rotated pages. * Allow class overriding for PSPDFSearchResultCell and PSPDFSearchStatusCell. * The grid control now loads faster for huge documents on iOS5. * Adds some additional safeguards that will now warn if methods of UIViewController/PSPDFViewController are overridden without calling super. * Removes legacy PSPDFResolvePathNamesEnableLegacyBehavior. * Fixes a small memory leak related to stamp annotations. * Fixes an issue where the search controller could get into an "empty" state without showing the search bar. ## 2.14.3 — 21 May 2013 * Allow to override PSPDFOutlineCell via overrideClass:withClass:. * Fixes a nasty issue with one-pixel white thumbnail borders on certain page aspect rations. * Fixes an edge case where the menu could appear while the PSPDFViewController is being popped from the navigation stack. * Fixes an issue with multiple calls to overrideClass:withClass: * Fixes a parsing bug with remote GoToR actions that have a page destination set. The page destination is now evaluated correctly. ## 2.14.2 — 19 May 2013 * PSPDFViewController now unloads its views when not visible on a memory warning even on iOS6. This saves memory especially when multiple stacks of viewControllers are used in a navigationController. * Improves the thumbnail quality. * Polyline/Polygon how shows boundingBox resize knobs + knobs for each line end point. Inner points are green. * When no fillColor is defined, color will be used instead of black. This is not defined in the PDF Reference, but more closely matches Apple's Preview.app and looks better. * Glyph ligature breaks (e.g. ffi) now no longer are marked as WordBreaker. * Improves default boundingBox calculation for new annotations on rotated PDF documents. * PSPDFPageRenderer can now be subclassed/changed. * Improves bounding box calculation for small FreeText annotations. * Stamps are now properly rendered on rotated pages. * If a stamp annotation is an appearance stream, PSPDFKit now tries to extract the image when using Copy/Paste. * Font variant picker now shows font in title and filters name for better display, e.g. 'Helvetivca-Bold' becomes just 'Bold'. * Several improvements to the PSPDFMultiDocumentController. * The thumbnail selection background now properly sizes itself based on the negative edgeInsets of the thumbnail cell (= looks better for non-portrait documents) * Dashed border now factors in lineWidth. * Improves parsing of certain GoToR Actions. * Made the color preview in UITableViewCell pixel perfect. * Improves title detection to filter out white space, now correctly handles cases where the title is missing but ' ' is set instead. * PSPDFKit is now compiled with -O3 (instead of -Os) and and uses link-time optimization to further improve performance. * Fixes placement of the image and signature picker for rotated documents. * Fixes a rare issue where a annotation could stuck in an invisible state because of a bug in the trackedView when selecting + scrolling happened at the same time. * Fixes a regression where thumbnail images could become sized wrongly in their aspect ratio under certain conditions for non-uniformly sized documents. * Fixes an offset by one error when resolving named destinations for a specific outline action destination type when there are > 500 outline entries. * Fixes a potential crash related to the color picker. * Fixes a crash related to parsing invalid outline elements. ## 2.14.1 — 15 May 2013 * Add write support for Polygon/Polyline annotations. (In the API, there's no UI for creating yet, but editing the points works) * Add new PSPDFThumbnailBar to display scrollable thumbnails as an alternative to the scrobbleBar. The thumbnail bar is a preview and might change API/Featureset in the next releases. We have some big plans for this but couldn't wait to get it out of the door! * The PSPDFOutlineViewController now no longer shows a title on iPad if no modes are set. As a detail, its search bar now is named as "Search Outline" instead of just "Search". * FreeText annotation is now correctly rotated on rotated PDF pages and also respects the annotation rotation setting (0, 90, 180, 270). * Fix password view state positioning when the keyboard is up and the parent resizes itself. * Fixes a potential regression/assertion when the PSPDFViewController was used without a navigationController. * Fixes an regression where words with ligatures (like the ffi liagure glyph) would be split into two words with certain encodings. * Fixes a race condition that could lead to a warning named ' deallocated while still in use'. * Fixes a line annotation serialization issue where line endings would only be serialized if both are set. * Fixes an issue for Copy/Paste where preexisting annotations could disappear after they have been copied and edited. * Fixes an exception in the PDF parser if a PDF with a corrupt stream object is analyzed. ## 2.14.0 — 12 May 2013 * Add support to Copy/Paste annotations. This creates a global UIPasteboard and will work for all apps that use the PSPDFKit framework with 2.14 and up. Alternatively a JSON object is created as well, so that other applications can add support to parse and support PSPDFKit-style-annotations as well. * Paste also supports general pasteboard types like Text, URL or Image and will create the appropriate annotations (if this is allowed) * New global PSPDFStyleManager that saves various annotation properties and applies them to new annotations. For example, if you change the color of a highlight to red, all future annotations are created red until you change the color back. This already worked in the PSPDFAnnotationToolbar before but is now unified and applied globally (will also save properties like fillColor or fontName). You can disable this with nilling out the styleKeys property of PSPDFStyleManager. * The PSPDFFreeTextAnnotationView is now always sharp, even when zoomed in. Because we have to work around the broken contentsScale property, the API has changed a bit. If you previously had textView overridden, you now need to subclass PSPDFFreeTextAnnotationView and change the textViewForEditing method to apply your custom textView. * PSPDFStampViewController is now more flexible and will evaluate the new PSPDFStampAnnotationSuggestedSizeKey key for the default annotations. Images in default annotations are now supported as well and the checkmark and X annotation are now added with the correct aspect ratio size. With the new setDefaultStampAnnotations: a different set of default annotations can be set. * Various smaller UX fixes inside the PSPDFNoteViewController. * Improves memory usage with very large documents (1000 pages and up) * Various smaller performance improvements in the cache. * Tinting has been improved for various view controllers. * The global "Text..." option has been renamed to "Note..." to make its function more clear. * The global "Appearance..." has ben renamed to "Style..." because this is more concise and better fits the iPhone. * Fixes an issue where unless controls:YES was set the wrong default was used for web links in the internal browser. * Fixes an edge case where the PSPDFPasswordView would not adapt itself correctly if the keyboard was already up before the controller has been pushed. * Fixes an issue with opening external URLs via dialog where the preview of the URL could fail. ## 2.13.2 — 10 May 2013 * The text selection delegate pdfViewController:didSelectText:withGlyphs:atRect:onPageView: is now also called for deselection. * Fixes an issue where PSPDFProcessor would flatten AND add annotations if kPSPDFProcessorAnnotationAsDictionary was used. * Fixes an issue with annotation drawing on iPhone on iOS5 where views could be reloaded after a memory warning and then the current drawing was missing. * Fixes a small memory leak. ## 2.13.1 — 9 May 2013 * Adds read support for Polygon/Polyline annotations, including support for all line ending types. * The tinted UIPopoverController subclasses now look much better and now very closely resemble the original including gradients and alpha value. * PSPDFTextParser now fully complies to NSCoding, so search results can be persisted and cached. (Thanks to ForeFlight!) * Fixes an unbalanced locking call when a page was requested that couldn't be rendered. ## 2.13.0 — 7 May 2013 PSPDFKit now requires QuickLook.framework, AudioToolbox.framework and sqlite3. Please update your framework dependencies accordingly. * Initial support for 'Widget' annotations, supports action and rendering. (not yet writable) * Support for 'File' annotations. Will offer QuickLook support on touch. * Basic read support for 'Sound' annotations. * Add support for 'Rendition' and 'RichMediaExecute' actions that can control Screen/RichMedia annotations. (video/audio. JavaScript is not supported.) * Ink/Circle/Ellipse/Line now each save their last used color independently. * FreeText and other annotation types inside the annotation toolbar now remember the last used color. * Add missing translation for "%d Annotations" and added special case for "%d Annotation" (singular). * Add missing "No Annotations" and "Loading..." state text for the PSPDFAnnotationTableViewController. * For text selection, the text knob is now prioritized over near annotations. * API: `cacheDirectory` in PSPDFDocument has been renamed to `dataDirectory`, so that won't be confused with the cache directory setting of PSPDFCache. * Improves text parser to properly detect word boundaries for documents that use invalid characters for word separation. * For pspdfkit:// based videos controls are now enabled by default if the option is not set. * PSPDFProgressHUD now checks if the keyWindow is visible before restoring, fixes an edge case with multiple windows that have rootViewControllers attached. * PSPDFSearchViewController now has a protocol to communicate with PSPDFViewController instead of owning that object directly. * PSPDFViewController no longer will change the viewMode to document when the view will disappear. * Fixes a rare crash when moving the text selection handle. * Fixes an issue with writing the page annotation object on malformed PDFs which could lead to annotations being written but not being displayed. * Fixes an issue with where sometimes fillColor was set on FreeText annotations even though there shouldn't be one set. ## 2.12.12 — 4 May 2013 * The note view controller now will detect links. * pdfViewController:shouldSelectAnnotation: is now also honored for long press actions. * Fixes an issue where annotations sometimes were not parsed correctly with password protected PDFs. * Fixes an issue related to checking the annotation cache receipt. * Fixes an encoding issue with annotation links that contained spaces. * Fixes a potential crash with an PSPDFActionURL with an nil URL. ## 2.12.11 — 30 Apr 2013 * Add new styles for HUD showing/hiding: PSPDFHUDViewAnimationSlide (in addition to the default fade) * Tapping in the previous/next range on first/last page will now toggle the HUD instead of force-showing it. * Fixes a UI issue where the document label view could be slightly offset under certain conditions on iPhone after a rotation from portrait to landscape with hidden HUD. * Fixes an issue with text extraction for certain PDF encodings. ## 2.12.10 — 30 Apr 2013 * Improves the Loading... state when there's already content in PSPDFTableAnnotationViewController. * Fixes an issue with adding/removing bookmarks. * Fixes an issue where fixedVerticalPositionForFitToWidthEnabledMode could lead to off-centered pages. * Fixes an issue with search and certain PDF encodings that only happened on release builds. * PSPDFKit Catalog: Fixes the map view example with a map:// annotation link. ## 2.12.9 — 28 Apr 2013 * Fixes an issue with text selection handle dragging. ## 2.12.8 — 28 Apr 2013 * Huge performance and memory improvements for text extraction/search. * Performance improvements at serializing annotations. * Memory improvements, especially for large documents. (>5000 pages) * API: useApplicationAudioSession in PSPDFVideoAnnotationView has been removed, since the underlying property is deprecated by Apple. Subclass and change this on the MPMoviePlayerController directly if you rely on the old behavior, but note that this might be gone as of iOS7. * New brightnessControllerCustomizationBlock in PSPDFBrightnessBarButtonItem. * Fixes an issue that could lead to a crash on deallocating certain objects when OS_OBJECT_USE_OBJC was enabled. (Sourcecode, iSO6 only ARC builds) * Fixes an issue where PSPDFKit was sometimes too slow freeing up memory with lots of background task running on low memory situations. ## 2.12.7 — 24 Apr 2013 * Major performance improvements on annotation parsing. * Outline and annotation parsing has been moved to a thread, the controller has now a loading state until parsing is complete. * The bookmark controller now supports the pageRange feature, hiding bookmarks that are not accessible. * Bookmark cells now allow copy. * Bookmark now also uses the PSPDFAction system to execute actions. (allows links, etc) * Improves the text parser to better deal with malformed PDF font encodings. * Improves accessibility localization in the thumbnail grid view cell. (thanks to Dropbox for providing this patch!) * Adds missing localization for text alignment property of free text annotations. * Fixes a regression where search table view updates with rapid cancellation could lead to an exception. ## 2.12.6 — 22 Apr 2013 * FreeText annotations now have a text alignment property (compatible with both Preview.app and Adobe Acrobat) * Ink annotations now allow setting a fill color (this is an extension to the PDF spec but works fine because we emit an appearance stream) * Allows subclassing of PSPDFStampViewController. * Expose the drawView of the PSPDFSignatureController. * FreeText annotations: Improve parsing of style strings. * Don't do expensive (xpc) dictionary lookups on older devices. (iPad1) * Fixes an issue where the outline controller could show menu items from the text selection view on iPad. * Fixes a crash with a missing selector (didReceiveMemoryWarning) on PSPDFDrawView. * Fixes a rare crash with parsing certain malformed PDF documents. ## 2.12.5 — 21 Apr 2013 * FreeText annotations now support fill color (Note: This is only partially implemented in Apple's Preview.app but works fine in Adobe Acrobat) * FillColor settings now includes transparent (useful for shapes, free text, lines) * Improves color parsing for FreeText annotations. * Add basic support for Caret annotations. * Improves rendering of rotated stamps. ## 2.12.4 — 19 Apr 2013 * Performance improvements for page scrolling. * Improves support for UIAppearance (e.g. navigation bar images) * Bookmark and annotation controller now fully respect the tintColor property. * API: PSPDFDocument convenience constructors have been renamed from PDFDocumentWith... to simply documentWith.... * Improves compatibility with certain GoToR PDF actions that don't define a target page. * Fixes an issue where pausing a video without controls could fail on iOS5. * Fixes an issue where showing multiple videos with autostart enabled could lead to a crash on iOS5. * Fixes a small memory leak when drawing stamp annotations. ## 2.12.3 — 19 Apr 2013 * The setDidCreateDocumentProviderBlock and the didCreateDocumentProvider method will now be called after the documentProviders are fully created, fixing recursion issues if methods are called that require the documentProvider from within that block. * Setting a different annotationPath in the PSPDFFileAnnotationProvider will remove all current annotations and try to load new annotations from that path. * Fixes an issue where in PSPDFTextSearch didFinishSearch: was always called, even when the search was cancelled (instead of didCancelSearch:) * Fixes an issue where changing the note icon could result in restoring the previously set note text. * Titanium: Fixes a bug where under certain conditions `useParentNavigationBar` would not work on the first push of the view controller. * Titanium: Add setAllowedMenuActions (document setting) ## 2.12.2 — 18 Apr 2013 * PSPDFTabbedViewController learned `openDocumentActionInNewTab`, opens a document in a new tab if set to YES (new default) * pdfViewController:documentForRelativePath: now gets the *original* path from the PDF action for resolvement. * Respect alpha for fillColor for FreeText annotations. * Disable iOS "Speak Selection" menu entries since this does not work. A DTS for this feature is ongoing. * Fixes rendering of textAlignment for FreeText annotations. * Fixes an issue when pageRange is set with multiple documents and retain documents are completely blocked through it. * Fixes PDF generation for different-sized PDFs. * Fixes missing update when "Clear All" is used. * Fixes a rare race condition on freeing document providers. * Fixes a rare issue that could lead to an empty view on loading a document. ## 2.12.1 — 12 Apr 2013 * Uses a sensible default for allowedMenuActions in PSPDFDocument. * Fixes an issue with Appcelerator. ## 2.12.0 — 11 Apr 2013 * New class cluster: PSPDFAction. This unifies action between PSPDFOutlineElement, PSPDFBookmark and PSPDFLinkAnnotation. Now you can create outline elements and bookmark that have the same flexibility as links in PSPDFLinkAnnotation, supporting pspdfkit:// style URLs. The parsing code has been unified as well with the best of both worlds (e.g. the 'Launch' action is now supported universally). This improvement required deprecating certain methods - update your code if you used one of those classes directly) * Add support for GoBack/GoForward named annotations. * Add basic support for JavaScript actions that link to another page. * PSPDFNoteAnnotationController now honors the allowEditing state also for the textView and blocks editing if set to NO. * New helper to better override classes: overrideClass:withClass: in both PSPDFViewController and PSPDFDocument. * Annotation types in the annotation table view are now localized. * New delegates in PSPDFViewControllerDelegate to get notified on page dragging and zooming. * PSPDFViewState no longer saves the HUD status (this should be handled separately and was confusing for the tabbed controller) * Removed legacy coder support for data models that were serialized before 2.7.0. * Removes deprecated API support in PSPDFTextSearch and PSPDFAnnotationParser. * Fixes an issue in the label parser where page label prefixes were defined without style. * Fixes an issue where hiding the progress HUD could make the wrong window keyWindow (if at that time there is more than one visible), thus leading to keyboard problems. * Fixes an issue in the document parser that could lead to a recursion for cyclic XRef references for certain PDF documents. * Fixes a situation where touch handling could become sluggish when a crazy amount of link annotation is on a page (>500!) * Fixes a annotation text encoding issue that could result in breaking serialization of certain character combinations like 小森. * Fixes a UI issue where invoking the draw action from the menu while at the same time having the annotation toolbar visible could lead to a hidden toolbar if that one is transparent. * Fixes an issue with the text extraction engine for certain PDF files. * Appcelerator: Allow setting size properties like thumbnailSize: [300,300] * Appcelerator: Add support to set outline controller filter options (outlineControllerFilterOptions = ["Outline"]) ## 2.11.2 — 4 Apr 2013 * Drawing annotations is now always sharp, even when the document is zoomed in. (This required changes to the public API of PSPDFDrawView, check your code if you use that class directly) * Annotation flattening now shows a circular progress indicator instead of the default spinning indicator. * PSPDFProcessor now has a new progressBlock property that calls back on each processed page. * New delegates: pdfViewControllerWillDismiss: and pdfViewControllerDidDismiss: to detect controller dismissal. * Add allowedMenuActions property to PSPDFDocument to allow easy disabling of Wikipedia, Search, Define text selection menu entries. * Internal locking of PSPDFDocument and PSPDFRenderQueue has been improved and is now faster in many situations. * Getting all annotations of a document is now faster in some situations. * Titanium: setEditableAnnotations: is now exposed (PSPDFKit Basic upwards) * Fixes an issue with line annotation selection where sometimes a selection knob was not visible. ## 2.11.1 — 3 Apr 2013 * Add switch to globally enable/disable bookmarks (`bookmarksEnabled` in PSPDFDocument) * `annotationsEnabled` in PSPDFDocument now also enabled/disables the annotation menus. * The thumbnail view now listens for annotation changes/bookmark changes and updates accordingly. * Fixes an issue where the toolbar in the new PSPDFContainerViewController was sometimes not displayed initially. * Fixes an issue where the delegate didLoadPageView: was called multiple times with the pageCurl transition. ## 2.11.0 — 1 Apr 2013 * Enables creation of Rectangle, Ellipse and Line annotations. * Line thickness can now be chosen from the drawing toolbar. * Improvements to line annotation drawing. * Line annotation endings can now be customized (Square, Circle, Diamond, Arrow,...) * Drawing is now instantly smoothened. * New annotation list controller (PSPDFAnnotationListViewController) to quickly see all annotations, zoom onto them or delete them. * Renamed Table of Contents to Outline. * OutlineBarButton now can show both the new annotation list and the bookmarks. Both are enabled by default. * The outline is now searchable. * Several menu items have been reorganized to both fit better on iPad and iPhone. * The long-press to show the bookmark view controller is now disabled by default. * The PSPDFKit folder has been restructured. * The `pageRange` feature if PSPDFDocument now works across multiple data sources. (This allows more flexibility for PSPDFProcessor and faster document creation) * It's now easier to disable the PDF page label feature with the new property `pageLabelsEnabled` in PSPDFDocument. (enabled by default, disable if you see 'weird' page labels) * API: PSPDFAnnotationView has been deprecated and renamed into PSPDFAnnotationViewProtocol. * Fixes an issue where small text on free text annotations was not rendered at all when the boundingBox was too small for it. * Fixes a potential crash on iOS5. ## 2.10.2 — 27 Mar 2013 * PSPDFCache is even smarter and faster when using PDF documents that are very slow to render. * PSPDFCache no longer deadlocks if you remove the delegate while the delegate is being called. * If a new PSPDFViewController is created based on a PDF action that links to a new document modally, all important settings are copied over to the new controller. * PSPDFKit will no longer create empty highlight annotations when using the annotation toolbar and tapping on a point without text. * No longer retains the view controller while the document background cache is being build (less memory pressure) * Adds some more safeguards against abuse of certain methods. * The render queue now retains the document while rendering. This fixes cases where image requests never returned because the document disappeared before. * Fixes a regression from 2.10 where through an event optimization sometimes the text of a note annotation was not properly saved. PSPDFDocument now sends out a PSPDFDocumentWillSaveNotification before a save will be made to give all open editors a chance to persist it's last state in time. * Fixes an issue where the contentRect was calculated wrong for uncommon view embedding use cases. * Fixes an issue where the thumbnail filter values were hardcoded. * Fixes a potential timing-related crash on iOS5 when the search controller was shown too fast. * Titanium: Add thumbnailFilterOptions property. ## 2.10.1 — 26 Mar 2013 * Shape annotations border and fill color can now be customized. * Clearing the memory cache will now also clear any open document references. * Add white color to common color picker colors (except for highlights, replacing purple) * PSPDFRenderQueue now has a cancelAllJobs to clear any running requests. * The render queue now better prioritizes between cache requests and user requests (zooms) to allow even faster rendering. * FreeText annotations can now no longer be created outside boundaries. * Add support for text alignment for FreeText annotations. (It seems that Adobe Acrobat has a bug here and ignores this property - other Applications are compliant to the PDF spec and do display this, e.g. Apple's Preview.app) * Edit mode now directly hides the HUDView. * API change: The color picker now has a context: flag to allow state storage. Update your delegates if you use this class directly. * Fixes some minor issues with the new cache. * Fixes a UI weirdness where the scrollview had a slow scroll-back animation when text was edited at the very top. * Titanium: Add new linkAnnotationHighlightColor property. ## 2.10.0 — 22 Mar 2013 PSPDFKit 2.10 is another major milestone. The cache has been rewritten from the ground up to be both faster and more reliable. Annotations are now cached, they are no longer an "afterthought" and will show up in the thumbnails and even the scrobble bar. The disk cache now limits itself to 500MB (this is customizable) and cleans up the least recently used files. The memory cache is now also smarter and better limits itself to a fixed number of pixels (~50MB of modern devices in the default setting). Loading images from the cache is now more logical and highly customizable with PSPDFCacheOptions. The two render code paths have been unified, PSPDFRenderQueue now does all rendering and can now render multiple requests at the same time and also prioritizes between low priority cache requests and high priority user zoom requests. In this process some very old code has been completely reworked (PSPDFGlobalLock) and is now much more solid. Several methods have been renamed, upgrading will require a little bit of effort to adapt to the new method names. It's definitely worth it. If you find any regressions or missing features for your particular use case, contact me at peter@pspdfkit.com. * Completely rewritten cache that now renders all screen sizes and shows annotations. * PSPDFThumbnailViewController now has a new filter to only show annotated/bookmarked pages. See filterOptions for details. http://twitter.com/PSPDFKit/status/314333301664006144/photo/1 * PSPDFViewController has a new setting: `showAnnotationMenuAfterCreation` to automatically show the menu after an annotation has been created. (disabled by default) * Text loupe no longer fades zoomed content. (looks better for text scope loupe) * Prevent too fast tableView updates (and thus flickering) in PSPDFSearchViewController. * Increases loupe magnification on iPhone to 1.6 and make kPSPDFLoupeDefaultMagnification customizable at runtime. * A UISplitViewController in the hierarchy is automatically detected and the pan gesture will be blocked while the PSPDFViewController is in drawing mode (else this would interfere with drawing). * The note annotation controller now no longer generates change events per typed key, but will wait for a viewWillDisappear/app background event to sync the changed text back into the annotation object. * Expose availableLineWidths and availableFontSizes in PSPDFPageView to customize menu options. * On iPhone, scrolling down the search results will now automatically hide the keyboard. * Improves performance for overlay annotation rendering. * Improves annotation selection, especially drawings are now pretty much pixel perfect. * Disables the long press gesture (and the new annotation menu) when a toolbar annotation mode is active. * Use PSPDFAnnotationBorderStyleNone instead of PSPDFAnnotationBorderStyleSolid when the border style is undefined (to match Adobe Acrobat) * The annotation selection border is now independent of the zoomScale. * FreeText annotations no longer "jitter" when resizing. * The stamp controller now dismisses the keyboard when changing switches or pressing return on the keyboard. * Allow note annotations outside the page area (to match Adobe Acrobat behavior). * Allow overrideClassNames for PSPDFDocument when it's created from within PSPDFViewController (e.g. when an external annotation link target is touched) * Add workaround against rdar://13446855 (UIMenuController doesn't properly reset state for multi-page menu) * The selectionBackgroundColor of PSPDFSearchHighlightView can be updated after it's displayed now. * PSPDFTabBarView of PSPDFTabbedViewController can now be overridden with the overrideClassNames dictionary. * API change: The renderBackgroundColor, renderInvertEnabled, renderContentOpacity methods have been removed from PSPDFViewController. Please instead update the dictionary in PSPDFDocument to set these effects. (e.g. document.renderOptions = @{kPSPDFInvertRendering : @YES}). * API change: PSPDFViewController's renderAnnotationTypes has been deprecated and will update the renderOptions in PSPDFDocument instead. * API change: renderPage: and renderImageForPage: will now automatically fetch annotations if the annotations array is nil. To render a page without annotations, supply an empty array as the annotations array (as soon as an array is set, auto-fetching will be disabled). * API change: PSPDFCacheStrategy is now PSPDFDiskCacheStrategy, the enum options have been updated as well. * Fixes some minor problems and deprecation warnings when compiling PSPDFKit with iOS6 as minimum deployment target and autoretained GCD objects. * Fixes an issue where some annotations got set to overlay and were not properly restored. * Fixes an issue with centering after returning from thumbnails in continuous scrolling mode. * Fixes an issue where a thumbnail could be animated that was not visible. * Fixes an UIAccessibility mistake where Undo was labeled Redo in the drawing toolbar. * Fixes encoding issues with localization files. * Fixes some potential crashes when parsing certain PDF documents. * Fixes several non-critical log warnings when opening continuous scrolling with an invalid document. * Fixes various potential crashes around screen annotations and stream extraction. ## 2.9.0 — 9 Mar 2013 * The loupe has been improved, it's now fast in every zoom level and now 100% matches UIKit's look. Developers can now easily update the magnification level. * Greatly improved UIAccessibility support. Reading mode is now line-based and reading column-based layouts works much better. * New feature: PSPDFScrobbleBar can control tap behavior outside the page area with allowTapsOutsidePageArea. * Improved PDF rendering speed for pageCurl mode. * RichMediaAnnotations (directly embedded video) now support autoplay set directly via Adobe Acrobat (Both page visibility modes will enable autoplay) * Removes deprecated methods from PSPDFViewController and PSPDFPageView. * NSNull entries are now properly filtered out from the PDF metadata. * Greatly improves outline parsing speed. In some cases parsing of extremely complex outlines went down from 120 seconds to 2 seconds (in a ~5000 pages document) * Add progress while data is transferring when using the "Open In…" feature. * PSPDFAnnotation model version is now at 1, boundingBox is now serialized as string and no longer as NSValue (fixes JSON serialization) * Improves animation when adding/removing bookmarks while the popover controller is resizing at the same time. * Add support for long-press toolbar button detection when useBorderedToolbarStyle is enabled. * useBorderedToolbarStyle is now also evaluated in PSPDFAnnotationToolbar. * PSPDFOpenInBarButtonItem now has the option to directly add the 'print' action into the list of applications. Disabled by default. See 'showPrintAction'. * UIMenuController is now smarter and no longer places the menu above the toolbar when there's space underneath as well. * 'allowTwoFingerScrollPanDuringLock' in PSPDFAnnotationToolbar now defaults to NO, since this delays drawing. * API change: Refactored the thumbnail view out of PSPDFViewController into it's own controller: PSPDFThumbnailViewController. If your code relied on modifying the collection view delegates within PSPDFViewController, you must update your code to override PSPDFThumbnailViewController instead. PSPDFViewController' gridView has been deprecated. Use thumbnailController.collectionView instead. * API change: Removed iPhoneThumbnailSizeReductionFactor. item size is now set conditionally during initialization. The best way to set this is in PSPDFCache.sharedCache.thumbnailSize. * API change: The delegate didRenderPage:didRenderPage:inContext:withSize:clippedToRect:withAnnotations:options: has been moved over to PSPDFDocumentDelegate. * Drawing Ink annotations now closely matches the line width when zoomed in. * Fixes a possible scrolling "freezing" issue when pageCurl is enabled. * Fixes a potential crash with extracting the page title of the PDF. * Fixes a potential crash when the Open In... action was invoked multiple times too quickly. (Thanks to Evernote for this fix) * Fixes a bug that could change the cursor position in the note annotation controller. * Fixes various potential crashes when parsing invalid PDF data. * Fixes an issue where thumbnails could not properly be selected with VoiceOver enabled. * Fixes an issue with image selection on rotated documents. * Fixes an issue with annotationViewClassForAnnotation: and the call ordering of defaultAnnotationViewClassForAnnotation. ## 2.8.7 — 22 Feb 2013 * Improved scrollview centering. Now enables pan while bounce-zoomed out. * PSPDFMultiDocumentController now can advance to next/prev document with tapping at the last page of the current one. * Slightly increases the smart zoom border on iPad. * New helper in PSPDFNoteAnnotationController to allow easy customization: setTextViewCustomizationBlock. * New property in PSPDFViewController: scrollOnTapPageEndAnimationEnabled. * New property in PSPDFViewController: shouldRestoreNavigationBarStyle (via Dropbox request) * Fixes a rare scroll view locking issues that was triggered by an UIKit bug. * Fixes an off-by-one error in PSPDFOutlineParser's resolveDestinationNameForOutlineElement. ## 2.8.6 — 20 Feb 2013 * PSPDFShapeAnnotation now creates appearance stream data. This is needed to work around a bug in Adobe Acrobat for iOS. This behavior can be disabled with setting kPSPDFGenerateAPForShape to @NO in renderingOptions of PSPDFDocument. As a side effect, this also improves display of transparent shapes with Apple's Preview.app * Improvements to smart zoom - text block choose method is now smarter. * viewLock no longer locks the HUD (just the view state) * Improves animation for the Table of Contents controller cells. * Setting the pageRange now automatically invalidates the current document. * PSPDFTabbedViewController has become more modular with the new superclass PSPDFMultiDocumentViewController. * Fixes a rare crash when using the drawing tool very quickly with only one resulting draw point. * Fixes a rendering issue with images added from the camera in pageCurl mode. * Fixes an issue where the scrobble bar could be displayed even though it's disabled. * Fixes a regression in the appearance stream generator. * Fixes a regression with updating the bookmark bar button status when the toolbar is transparent. * Titanium: Fixes toolbar detection for annotation toolbar. ## 2.8.5 — 16 Feb 2013 * Fixes a text glyph frame calculation bug when a font contains both a unicode map and an encoding array. * Improves glyph shadow detection to be more accurate, less false positives. ## 2.8.4 — 16 Feb 2013 * Improves text block detection speed. * Fixes certain crashes when parsing malformed PDFs. * Fixes an issue where outline elements linked to the same named destination would not all be correctly resolved. ## 2.8.3 — 15 Feb 2013 * Allow UIAppearance for PSPDFRoundedLabel. * Added a mailComposeViewControllerCustomizationBlock in PSPDFEmailBarButtonItem to easily change the default email body text. * New property: thumbnailMargin in PSPDFViewController. * Thumbnail view now dynamically updates the sectionInset if the HUD is hidden during thumbnail view. * API change: Renamed siteLabel to pageLabel in PSPDFThumbnailGridViewCell. * Replaces PSPDFAddLocalizationFileForLocale with the more flexible PSPDFSetLocalizationBlock. * Add double-tap to fullscreen for YouTube views. * Add fallback to use associated objects for annotation views that don't comply to PSPDFAnnotationView. (Fixes duplicate view adding) * Disables the yellow block highlighting on a double-tap zoom. * The Save To Camera Roll is now faster and no longer blocks the main thread during JPG compression. * Certain smaller tweaks/improvements for the HUD. * Fixes a regression where on a long press the annotation menu would reappear then disappear for highlight annotations. * Fixes a regression that broke re-positioning of search highlights on a frame change. * Fixes an issue where the pdfController could be dismissed when using the "send via email" feature. * Fixes a rare condition in which the progressView (PSPDFProgressHUD) could get stuck. * Fixes an issue where videos that were set to autostart=NO could still autostart on iOS5. * Fixes an issue where CMYK encoded JPGs would be extracted inverted upon saving. * Fixes an issue where ink annotations could be added in the wrong size when the device directly rotates after finishing a drawing * Fixes a rounding error that made certain pages scroll-able in pageCurl mode. * Fixes a page blurriness issue because of rounding errors when zooming out/zooming in a lot. * Removed deprecated options from PSPDFEmailBarButtonItem. ## 2.8.2 — 10 Feb 2013 * HUD visibility/transparency can now be set more fine-grained with the new properties transparentHUD, shouldHideNavigationBarWithHUD, shouldHideStatusBarWithHUD and statusBarStyle. Check your code and let me know if this breaks something. Setting statusBarStyleSetting will update all those properties. * Resize view now snaps to aspect ratio on resizing. Middle knobs are hidden if space is low. * Document link annotations now resolve symbolic links. * After editing annotation properties (e.g. color) the menu will re-appear. * Annotation menu is re-displayed after a rotation. * Finishing a drawing no longer disappears/reappears because of the page rendering process. * Search view controller cells now animate better and have better sized margins. * PSPDFBarButtonItem's pdfController property is now weak. Update your code to use notifications if you previously relied on KVO. * NavigationBar/ScrobbleBar are now rasterized before a fade out/fade in, which improves the fade animation (no more bleed-through) * Annotation Toolbar now in all cases correctly adapts to statusbar frame size changes (calling, personal hotspot,...) * Improves compatibility with writing PDF trailer data with certain corrupt PDF files. * Adds new helper: PSPDFAddLocalizationFileForLocale, parses a localization text file. * Fixes an UX issue where the annotation tool could be deselected when using the two-finger scroll while the annotation toolbar is active and a tool (e.g. highlight is selected). * Fixes a touch inconsistency where a annotation deselection could be done without marking the touch as processed. * Fixes several entries in the localization table. * Fixes a regression introduced in 2.8.1, a potential crash when using the highlight annotation tool outside of a glyph. * Fixes a potential crash in the search view controller due to invalid state handling. * Fixes an issue where part of the drawing state was lost when opening a modal controller while in drawing mode. (e.g. iPhone/color picker) * Various typos fixed, and some very minor API changes due to spelling corrections (thanks to Tony Tomc). ## 2.8.1 — 6 Feb 2013 * The highlight tool now matches full words. A single touch will highlight the complete word instead of just one character. * A new syntax for link annotations to control UI. For now pspdfkit://control:outline is supported to open the TOC directly from the document. * The signature controller now uses "Signatures" as title instead of "Choose Signature" on iPhone, since later was too long and got cut off. * Fixes an issue where setFileURL: could generate a new UID if one was already set. * Fixes an UI issue when resizing an annotation purely horizontally would result in no redraw. * Fixes an UI issue where the thumbnail indicator could move behind the thumbnail image in some cases. * Fixes an UI issue in PSPDFFixNavigationBarForNavigationControllerAnimated() that could potentially shift down the navigationBar for unusual view controller setups. * Fixes an UX issue where a second tap was sometimes required after using certain modes in the annotation toolbar. * Fixes an issue where an external PSPDFBarButtonItem would not update on iPhone. * Fixes an issue where videos played in a popover continued to play even after the popover was dismissed. * Fixes an issue where thumbnailSize could not be changed after the PSPDFViewController has been displayed. * Fixes an issue with incorrect view controller locking after switching from highlight to draw mode in the annotation toolbar. ## 2.8.0 — 5 Feb 2013 * Image annotations. PSPDFKit can now add images from the camera and the photo library and embed them as stamp annotations. * Search / Text extraction is now more than twice as fast and reports the current page. * The whole AP stream generation system has been improved and performance optimized to allow bigger streams like images. * PSPDFKit will now require Xcode 4.6/SDK 6.1 to compile. (4.5 should still work fine, but we follow Apple's best practice with always compiling with the latest SDK available.) * API change: editableAnnotationTypes is now an *ordered* set. Using a regular set to change this property will work for the time being, but please update your code. The order now will change the ordering of the buttons in the annotation toolbar and the new annotation menu. * Add experimental phone/link detection: detectLinkTypes:forPagesInRange: in PSPDFDocument. This will create annotations for phone numbers and links found in the document, if they are not linked already. This is the same that Preview/Mac and Adobe Acrobat do - they allow to click URLs even if they don't have any link set on them. * Search now displays the current processed page. * Further tweaks to PSPDFHighlightAnnotation highlightedString. * Add setting to enable/disable the "Customer Signature" feature. (customerSignatureFeatureEnabled in PSPDFSignatureStore) * The signature controller has now landscape as preferred rotation under iOS6. (but still supports portrait) * Controllers presented via the PSPDFViewController helper now use a custom PSPDFNavigationController that queries the iOS6 rotation methods of the topmost view controller. This makes it easier to customize rotation for PSPDF* controllers without hacks. * Performance improvement: deleted annotations now are no longer serialized if the external annotation format is used. * The "hide small links" feature now works better on iPhone. * FreeText annotations now parse even more font definition styles. * Improvements to the heuristic in PSPDFHighlightAnnotation highlightedString. * Annotations added via a modal view (e.g. Signatures on iPhone) are now also selected. (annotation selection is preserved during reloadData) * Smart zoom now uses less border when zooming into a text block, which looks better. (other columns usually are no longer visible) * Taps that dismiss an annotation editing popover no longer modify the HUD state. * The scrobble bar thumbnail size has been tweaked to be a little bigger. This now can also be fine-tuned, see PSPDFScrobbleBar.h. * The font selector now selects the currently chosen font. * Various performance improvements. (esp. search and the color picker) * Thumbnails are now sharper and always aligned to pixel grid (fixes a bug in UICollectionViewFlowLayout) * Text selection knobs are now pixel aligned as well. * When thumbnails are loaded from scratch, they are loaded in order. (PSPDFCache's numberOfConcurrentCacheOperations has been set to 1) * Fixes an UX issue where PSPDFKit could end up displaying something like '1 (1 of 2)' for page labels. * Fixes an UX issue where a tap wasn't set to being processed when the delegate delegateDidTapOnAnnotation:annotationPoint:... was being used. * Fixes an UIKit bug that in some cases froze the UIScrollView when we zoomed out programmatically (e.g. a double tap after already zoomed in) * Fixes a potential crash when saving NSData-based PDFs with a corrupt XRef table. * Fixes a rendering issue where some landscape documents were incorrectly scaled when using renderImageForPage:withSize in PSPDFDocument. * Fixes a regression that stopped the [popover:YES] option form working properly. (A formsheet was presented instead) * Fixes a regression in the 2.7.x branch that caused movies loaded in the PSPDFWebViewController to fail with the error "Plugin handled load". * Fixes an issue when using Storyboard and setting the viewState to thumbnails initially. * Fixes an issue where the signature selector controller dismissed the whole pdfController under certain conditions. * Fixes an issue with annotations moving to other pages on a document with multiple document providers. * Fixes an issue where the note view controller would hide the close button on iPhone if edit was set to NO. * Fixes an issue with frame displacement under certain conditions on embedded UINavigationControllers. * Fixes an issue with zooming when in text edit mode and page centering. * Fixes an issue with searching for certain characters that are reserved regex characters (like []()\*+). * Fixes an encoding issue with annotation content and certain Chinese characters. ## 2.7.5 — 25 Jan 2013 * Signatures are now securely saved in the Keychain and a list of signatures is presented. To disable this feature, set PSPDFSignatureStore.sharedSignatureStore.signatureSavingEnabled = NO in your appDelegate. * While annotation mode is active (highlight, drawing, etc) scrolling is now enabled with using two fingers. The old behavior can be restored with setting allowTwoFingerScrollPanDuringLock in PSPDFAnnotationToolbar to NO. * PSPDFKit now requires Security.framework. * Fixes an issue that could cause an initial "white page" when the controller is first loaded, even when there's cache data available. * Fixes an UX issue where, with creating a new note, the menu could be displayed on iPhone, stealing the keyboard from the newly created note controller. * Fixes a regression of 2.7.4 that broke some remote videos/audios. * Fixes a potential issue when reordering bookmarks. * Fixes an issue where the last letter was cut off when using PSPDFHighlightAnnotation highlightedString. ## 2.7.4 — 24 Jan 2013 * Line annotations are now writeable. * A second tap now enables the edit mode in a free text annotation. * Annotation selection is now properly pixel aligned, resulting in sharper border, drag points and content - especially on the iPad Mini. * The drawing toolbar no longer forces the HUD to show before displaying itself. * If enableKeyboardAvoidance is set to NO, the firstResponder won't be tampered with anymore. * New property: allowToolbarTitleChange on PSPDFViewController, controls it title is set or not. * PSPDFOutlineParser now lazily evaluates named destinations if an outline has more than a specified threshold. (This is currently set to 500). This greatly improves loading times for documents with complex outlines. * Allow audio file types for RichMedia/Screen annotations. * Add more audio file formats to the support list. (aiff, cif,...) * Ensure that addAnnotation:animated: in PSPDFPageView sets the page and documentProvider. * Better workaround for MPMoviePlayer's problem with multiple audio/video views on the same window. (A play button is now displayed in those cases) * Normalizes extracted text, allow searching within text that contains non-normalized ligatures. * Opacity menu now draws a checked white background instead of using the menu background (now it's more like Photoshop, looks better) * Add spanish translation (thanks to Tony Tomc!) * The maximum software dimming value is less dark. * Fixes a problem in PSPDFProcessor with NSData-based documents and adding annotation trailers. * Fixes a bug where the scrollview would update it's position when a UIAlertView with a TextField was visible. * Fixes a bug in the outline parser that resulted in the loop for (invalid) cyclid PDF referenced objects. * Fixes an issue where parsing certain PDF dates failed. * Fixes an issue with view state restoration and continuous scrolling. * Fixes a rare issue where the bookmark thumbnail view indicator could be behind the thumbnail image. * Fixes an issue with inline editing and the split screen keyboard. ## 2.7.3 — 20 Jan 2013 * FreeText annotations are now editable inline. * Improves stamp and signature rect placement (no longer places the rect outside of page boundaries) * Drawing overlay is now transparent. You can restore this behavior with subclassing PSPDFDrawView and setting the backgroundColor to [UIColor colorWithWhite:1.0 alpha:0.5]. * When changing the thickness of a drawing, the selection border will now automatically adapt itself to fit the new bounds. * Renamed "Colors..." menu entry to "Color...". * Fixes a potential issue with annotation rotation handling. * Fixes a potential crash on stamp creation on iPhone. * Fixes an issue where the drawing toolbar was added behind the HUD toolbar. * Fixes an issue where PSPDFKit could end up displaying something like 'Page 2-3 of 2'. * Fixes an issue where certain pages could be skipped with scroll to prev/nextPage in double page mode (via touching the borders). * Fixes some typos and spelling mistakes. ## 2.7.2 — 18 Jan 2013 * PSPDFScrollView will now move up if a keyboard is displayed. * Free Text annotation now have sensible defaults when created in code. (Helvetica, font-size 20) * Several tweaks for PSPDFProcessor PDF from web/office files generation. * Fixes a potential crash in the iPhone popover controller. * Fixes in the annotation selection handling logic. * Fixes a minor UX issue where Open In... could result in a second tap needed to activate. ## 2.7.1 — 17 Jan 2013 * Note annotation flattening. * Text selection is now always prioritized over image selection. * For the continuous scrolling page transition, all visible pages are now animated when showing/hiding the thumbnail view. * Improve PDF serialization of custom stamp annotations. * Fixes an animation issue with continuous scrolling. * Fixes an UI issue where under certain conditions a second tap was required on a toolbar button to hide the active popover. * Fixes an UI issue with creating note annotations. * Fixes an issue where annotation resizing was disabled when textSelectionEnabled was set to NO. * Fixes a rounding bug in continuous scrolling that could lead to a x AND y scrolling on zoomScale 1.0 * Fixes several issues with certain RichMedia embedded video annotations. ## 2.7.0 — 16 Jan 2013 * PSPDFKit model classes now have a common base model class 'PSPDFModel' - enables serialization/deserialization via JSON easily using externalRepresentationInFormat:. To get the JSON dictionary, use annotation externalRepresentationInFormat:PSPDFModelJSONFormat. (The old annotation serialization format is still supported for the time being) * PSPDFKit now requires AssetsLibrary.framework - if you're using PSPDFKit.xcproj or the source distribution, this is already been taken cared of. If you added the frameworks manually and get a linker error, make sure you are linking sAssetsLibrary.framework. * PSPDFMenuItem learned to show images in UIMenuController - this beautifies many of the annotation menus, images are now used for annotation types/colors where appropriate. * PSPDFKit has learned to write appearance streams. Currently they are emitted for Stamp and Ink annotations. This will help to further improve annotation compatibility with some apps that behave less standard compliant (like Adobe Acrobat/iOS, last tested version is 10.4.4, which doesn't show Ink annotations if they do not have an attached AP stream, even if this is invalid behavior according to the PDF spec. (GoodReader/Preview.app/Adobe Reader on the Mac don't require an AP stream and work in compliance to the spec.)) * Annotation menus have been cleaned up a little, Opacity... has been moved into a submenu of Color for highlight annotations. * PSPDFProcessor has learned to write annotations as dictionary, not only flatten. This will be used e.g. for Open In... when the original PDF is not writeable and thus annotations are saved in an external file. * Open In... will now create a new file if there are annotations and the source PDF is not writeable itself. * Stamp annotations now have limited support for appearance streams. * Stamp annotations can now be added via the new PSPDFStampViewController. * Add experimental pageRange feature in PSPDFDocument to allow showing of a subset of the pages. * Highlight annotation hit testing is now more accurate, checking the specific rects of the highlights, not the outer boundingBox. * Annotation rendering now checks if the annotation will be visible at all and only then renders the annotation. This speeds up zooming on complex documents with many annotations. * Improves search by ignoring certain whitespace characters like no-break-spaces. * Enables creation of password protected PDFs with PSPDFProcessor up to AES-128 (and mix other CGPDFContext properties like kCGPDFContextAllowsPrinting or kCGPDFContextAllowsCopying) * Improves word detection with splitting words between a line of thought and adding special logic for non-default whitespace characters. to use the old behavior. * Improves french translation. * zIndex of annotation images is now below zIndex of links, so that links are always displayed before annotation images. * Email sending using PSPDFEmailSendMergedFilesIfNeeded will not perform a merge if there is only one source document. * Links are now handled even if they are overlapped or hidden underneath other views. * Hides the page label and the scrobble bar if the document is password protected and not yet unlocked. * PSPDFAnnotation now shows if an appearanceStream is attached. * PSPDFAnnotation now as a userInfo dictionary to add any custom data. * Annotations now have a creationDate. * When note annotations are tapped, don't fade-animate the former annotation out. * Page label will not be displayed if the page label is simply the real page number. (Prevent titles like 2 (2 of 10)) * The internal web browser will now display an error within the HTML, much like Safari on iOS: https://twitter.com/steipete/status/287272056524001280 * Selected images now have a (default iOS light blue) selection state, matching the selection behavior of glyphs. * Brightness control now has indicator images for less/more brightness and a better icon. * Improves performance for pages with many links by dynamically disabling the rounded corners in that case. * External PDF links can now be opened modally in a new controller, use [modal:YES] in the option field, e.g. pspdfkit://[modal:YES]localhost/two.pdf#page=4. * Video extension with a cover now no longer has a dark background and is transparent. If you set cover:YES it will simply show the play button without any background. * API change: Words are now detected if they are completely within the rect specified. Use kPSPDFObjectsTestIntersection * API change: OutlineElement.page is now 0-based, not 1-based. * API change: Several PSPDFProcessor methods now have an additional error part. * API change: PSPDFInkAnnotation has been simplified, will automatically recalculate bounding box and paths on line change. * API change: Setting the annotation color will now also set the alpha value, if one is set in color. * API change: objectsAtPoint: now automatically does an intersection test unless specified otherwise, but objectsAtRect will not, so you need to specify that. Also, in previous version the rect check was done incorrectly to check if the test rect is within the object, now we check if the object is within the test rect OR intersects with it, if intersection is set to YES. * API change: Links to external files now reference the page, not page+1. (pspdfkit://localhost/two.pdf#page=4 will move to page 4, before it was page 5) * Add support for older PDF standard of defining Dest arrays for page links (for example those produced by LaTeX with PDF version 1.3) * Annotation option parsing is now more robust and will tolerate whitespace. * Annotation text (and thus the annotation menu) is now even displayed if editableAnnotationType is set to NO. * Adds a workaround for certain PDFs with large embedded videos that previously couldn't be parsed. * PSPDFKit now uses OS_OBJECT_USE_OBJC instead of OS version checking to check of GCD objects are collected via ARC or not (This is iOS6 only and the new default, can be disabled by the compiler) * Text in the password view is now viewable on iPhone in landscape. * Fixes an issue with font caching on search and certain documents. * Fixes an off-by-one error on writing link annotations that link to internal pages. * Fixes an issue with the "Save To Camera Roll" feature and iOS6 - the required rights are now checked fore before writing the image, and an error dialog is displayed for the user in case image saving failed. * Fixes an issue where PDF images in CMYK format could not be saved to the Camera Roll. * Fixes an issue where PSPDFTabbedViewController failed to show the tab bar if restoreState wasn't called and thus the documents array was nil. * Fixes an issue with opening internal html links on PDF link annotations on the device (worked fine on the Simulator) * Fixes an issue where the cancel button of the search controller was disabled sometimes (iPhone only) * Fixes an issue where under certain conditions link annotations were marked as dirty right after reading them from the PDF which could result in some slowdown when hiding the PSPDFViewController. * Fixes a crash with LifeScribe PDF documents when there's an embedded video annotation. * Fixes a weird potential crashing issue where setting the controlStyle of the MPMoviePlayerController could throw an exception (which is not documented and should not happen according to the MPMoviePlayer documentation). * Fixes a bug that prevented setting of the defaultColorPickerStyles. * Fixes an issue where the cover view of movie annotations showed outdated content in some cases. * Fixes a potential stack overflow when a PDF that had recursive XObjects with font informations was parsed. * Fixes an UIKit bug where the statusbar sometimes was placed above the navigationBar on certain occasions. * Fixes issue where certain isOverlay=YES annotations became unmovable after a save until the page had been changed. * Fixes issue where a highlight annotation was re-added to the backing store after a color change. * Fixes an issue where encryptImage:fromDocument: wasn't actually using the encrypted data. * Fixes an issue in the text extractor with parsing certain special formatted CMaps wit bfranges. This should especially help for text extraction errors in languages like turkish or chinese. * Fixes a missing setter for PSPDFLineAnnotation. * Fixes a retain cycle with PSPDFAnnotationToolbar because the delegate was retained. * Fixes a issue with AES-128 encrypted documents that failed to open with a "failed to create default crypt filter." error. * Fixes the delegate in the PSCAnnotationTestController (thanks to Peter Li) * Titanium: Fixes several issues and adding compatibility for Titanium 3, also added new searchForString(string, animated) and setAnnotationSaveMode(1) functions. ## 2.6.4 — 21 Dec 2012 * Note annotations now adapt itself to the zoomScale and are no longer scaled when zooming in. * Note annotation dragging has been unified with all other annotation types (Notes are now selectable as well) * Text/Note annotation popover is now less modal and allows one-touch clickthrough to other annotations and UI. * New annotationContainerView container in PSPDFPageView makes it easier to coordinate the zIndex of annotation views with your own custom views. * Add encryption/decryption block helper for PSPDFCache. (PSPDFKit Annotate feature) * Moved MFMailComposeViewControllerDelegate to PSPDFViewController (from PSPDFEmailBarButtonItem) * Annotations now have a new isResizable that controls if they can be resized or not. * With + (void)setDefaultColorPickerStyles: in PSPDFColorSelectionViewController the default color pickers can be configured easily. (e.g. disable the new HSV Picker) * Better support for annotation borders. * Improves performance for text extraction engine with cyclic XObjects. * No longer breaks between a word after a font ligature. * Properly sets the cropBox for each page in PSPDFProcessor. * Adds a fallback for weird URI encodings on link annotations. * No longer sets the title for the internal web browser if that is nil (show URL instead) * Fixes a bug on toolbar building with correctly adding the moreBarButtonItem when the first button is filtered. * Fixes an issue where the signature jumped to a different page when added to the right page in landscape mode. * Fixes an issue with the initialization of the continuous scroll mode (especially when using it within a childViewController) * Fixes an issue with text extraction on fonts that don't define any base encoding. * Fixes an issue where custom bookmark names were not correctly saved. * Fixes an issue with video rotation and iOS 5 - current page state is now preserved in all states. * Fixes a potential crash when annotations were written back that do not define any color information. * Titanium: Fixes issue with the didTapOnAnnotation callback and event. ## 2.6.3 — 17 Dec 2012 * New font picker for FreeText annotations. * Allow changing the text color of the free text annotation. * FreeText annotations will now persist the color state. * Supports more formats for textColor and fontName in free text annotation. * Selected annotations are now rendered in full resolution and no longer appear blurry when zoomed in. * Don't block double tap for selected annotations that are not movable (like text highlights) * After creating a note or a freetext annotation, the toolbar will be set to none. (to match iPad behavior) * Fixes color picker placement for annotations when zoomed all the way in. * Fixes various minor issues with annotation menu showing/placement. * Fixes a UI issue where the Open In... menu didn't disappear on tapping the button a second time. ## 2.6.2 — 16 Dec 2012 * New HSV color picker. * Color picker now selects the page where the color is selected, or the generic picker if none of the palette colors matches. * Brightness control is now properly displayed within a custom popover on iPhone. * Highlight selection control now selects using the natural text flow, not just the selected rect. (Preview: https://x.com/nutrientdocs/status/279636900590006272) * Further improve document shadow for non-equal sized documents. * Undo/Redo buttons now have icons instead of text. (Annotation drawing toolbar) * Open In... now asks for flattening. * Print now optionally allows annotation printing. * Ensure documentProvider is always added when annotations are added. * Add support for annotation links like tel://4343434 and generally improves handling of external URLs. * Add support for PDF labels that have a offset and are plain numbered labels. * Fixed a rare condition where menus within UIMenuController could fail to execute their block target. * Fixes an issue where PSPDFNoteAnnotation sometimes used the wrong overrideClassNames dict for lookup. * Fixes a situation where pdfViewController:didDisplayDocument: wasn't called correctly. * Fixes issue where in pageCurl mode after selecting a new color on iPhone the drawing overlay vanished. * Fixes crash when trying to change highlight annotation type on long-tap. * Adds a workaround for an UIKit bug that only appears on iOS 5 with videos that are playing inline and have a incorrect frame after exit from fullscreen. ## 2.6.1 — 10 Dec 2012 * Video annotations can now have a specified offset. (e.g. offset=10) in seconds. Optional parameter. * PSPDFResizableView can now optionally be set in a way that it only allows moving, not resizing. * New toolbar style option in PSPDFViewController: useBorderedToolbarStyle. Will add regular bordered toolbar buttons. Optional. * tintColor can now be changed after the PSPDFViewController has been displayed. * Fixes an issue where video was autostarted even if autostart was set to NO. * Fixes an issue where the last toolbar item on the right toolbar could vanish if the style is bordered. * Fixes some issues regarding the textParser. More documents are now supported (especially with multiple nested XObject streams) * Fixes an issue where PSPDFStatusBarDisable could sometimes trigger statusbar showing/hiding. ## 2.6.0 — 9 Dec 2012 * New feature: Add signature. It's enabled by default. If you don't need it, set the editableAnnotationTypes on PSPDFDocument. * New Opacity... menu item for Ink and Highlight annotations. This can be disabled via the menu delegates (PSPDFViewControllerDelegate) * New Create Annotations menu after a long-tap on a space without text or image. This is now enabled by default. See createAnnotationMenuEnabled on PSPDFViewController. * Improved text block detection (this also improves smart zoom) * New convenience method defaultAnnotationUsername in PSPDFDocument. You should set this to the user name if you're using annotations. * DualPage display will now center pages vertically if they don't have the same aspect ratio, and will draw a nicer shadow spanning exactly both page rects. * PSPDFProgressHUD now has support to show a circular progress status. (Try the new Dropbox upload sample) * Exposes applicationActivities and excludedActivities in PSPDFActivityBarButtonItem. * Adds support for Web/Email URLs in the PDF Outline. * Adds a workaround for an UIKit bug that could result in an partly unresponsive scrollView when zooming out programmatically all the way to zoomLevel 1.0 (e.g. after tapping an already zoomed in text block, only affected the default pageTransition, only on device) * If only Highlighting is allowed (and not Underscore or Strikeout), the Type... menu option will be hidden (since there is no point one could change it to) * PSPDFScrobbleBar now has left/rightBorderMargin properties. (e.g. to make space to a custom button at one end) * Allows subclassing of PSPDFThumbnailGridViewCell via overrideClassNames. * Uses the shared alpha property for fillColor, to be compliant to the PDF standard. (mostly affects shape annotations) * Ensure annotation selection is cleared before a pageCurl transition starts. * Simplifies toolbar code by removing the copiedToolbar subclasses. (This should not affect your code at all, simply found a better way to trigger UIKit to refresh the image property) * Fixes a rare crash for parsing certain MMType1 PDF fonts. * Fixes an issue where the annotation toolbar could be overlaid by the underlying toolbar buttons when the toolbar (not navigationBar) was updated afterwards. * Fixes an issue where the search highlighting was incorrectly applied on certain rotated documents. * Fixes a bug where under certain conditions the initial page set on the PSPDFViewController was ignored. * Fixes an issue where not rendered annotations where still selectable. * Fixes a situation where the PDF annotation user wasn't written unless contents was set. * Fixes an issue where the page offset for document providers sometimes was calculated incorrectly, this showing the wrong page labels. * Fixes a crash on iOS6 when viewMode was set to PSPDFViewModeThumbnails before the controller was actually displayed. * Fixes an issue where a late view frame change could result in an incorrectly rendered PDF view (black borders, could happen under certain conditions with Storyboarding) * Fixes a bug with using brightnessBarButtonItem on iPhone. * Fixes a situation where one could initiate a pageCurl during adding an annotation. * Titanium: Fixes an issue where setLinkAnnotationBorderColor would not work on the first page. Also adds support for "clear" color. ## 2.5.4 — 26 Nov 2012 * Makes PSPDFLinkAnnotation writeable and adds a new targetString method to customize the preview URL that is displayed on a long press annotation. * PDF link annotations are now editable. This is not added by default. Enable this by adding PSPDFAnnotationTypeStringLink to the editableAnnotationTypes of PSPDFDocument. * PSPDFAnnotation now parses and write the name (NM) property. (Optional, used to uniquely identify PDF annotations) * Exposes some new methods in PSPDFNoteViewController. * Expose PSPDFPageView's showLinkPreviewActionSheetForAnnotation:fromRect:animated to allow customization of the link preview sheet (invoked on long press) * Ensures that the minimum size of annotations is not smaller than the current size (to prevent weird resizing) * Fixes a potential wrong private API detection issue where "visibleBounds" was incorrectly flagged. * Fixes an issue where the search controller was sometimes misplaced when search was directly invoked from the selected text. * Fixes an issue where scrolling was disabled when setting a document delayed in scrollperpage mode after no document was set before. * Fixes an UI glitch where the page label background was blurry for certain conditions. * Fixes a rare issue where the background color of a link annotation could get stuck when using inter-document links. ## 2.5.3 — 24 Nov 2012 * Enables rendering of certain annotations as always overlay and still preserve movement features. * Fixes for text selection handling, especially for -90/270 degree rotated documents. * Fixes image selection rects for rotated documents. * Fixes a crash with searching certain arabic documents. * Fixes a one-pixel-bleedthrough in between the pages in dualPage / pageCurl mode. ## 2.5.2 — 22 Nov 2012 * New convenience helper: setUpdateSettingsForRotationBlock in PSPDFViewController. (e.g. to switch between pageCurl and scrolling on rotation) * Moves the logic that returns the default classes for supported annotations out of PSPDFFileAnnotationProvider into PSPDFAnnotationProvider - so if the annotationProvider is customized to use only custom annotation providers, annotations will still work. * Handles corrupt PDF more gracefully, failing faster (esp. important if you're using a custom CGDataProvider) * Search no longer searches between words (but between lines) * API: Renamed fixedVerticalPositionForfitToWidthEnabledMode to fixedVerticalPositionForFitToWidthEnabledMode. * Turned on a lot more warnings (like missing newlines.) PSPDFKit is now warning free even under pedantic settings. * Fixes a UX issue where sometimes a second tap was needed to show the bookmark view controller. * Fixes a crash when deleting bookmarks that has a custom name. * Fixes the delegate call pdfViewController:annotationView:forAnnotation:onPageView: (wasn't called before due to a typo in the selector check) * Fixes an issue with generating link annotations in code using the initWithType initializer. * Fixes an issue where overrideClass wasn't checked for PSPDFWebViewController in one case. * Fixes an issue that could result in a non-rendered PSPDFPageView if the scrollView contentOffset was set manually without animation. * Fixes an issue where the text block detection could take a very long time on some documents. * Fixes an issue where a log warning was displayed when a highlight annotation was loaded from disk. * Fixes an issue where a low memory warning while editing annotation could lead to a non-scrollable document and/or a not saved annotation. * Fixes an issue where the keyboard was no longer displayed automatically for new text annotations on iPhone. * Fixes an issue where note/text annotations could be mis-placed when a document has a non-nil origin and a non-nil rotation value. ## 2.5.1 — 19 Nov 2012 * Dismisses the search bar keyboard at the same time the popover fades out, not afterwards. * Exposes some more methods on PSPDFAnnotationToolbar. * Fixes an issue with text selection being offset/invalid for certain documents (this change fixes A LOT of documents that previously had problems) * Fixes an issue with text encoding on some PDFs. ## 2.5.0 — 17 Nov 2012 * Images can now be selected and copied to the clipboard or saved to the camera roll. There's a new delegate to customize this. * A long-press on an annotation will switch over to edit-mode. Either moving if allowed, or showing the menu and cancelling the gesture if not. * Changes the default PDF Box back to kCGPDFCropBox. You can customize this with using the "PDFBox" property on PSPDFDocument. * Annotations can now be moved and resized, and the selection view is much sexier now (matches popular iOS apps like Pages) * Words are highlighted as they are being highlighted using the annotation toolbar. * Update color picker to include more colors and for better use space on iPhone 5 and iPad. * Default drawing color is now blue. * Highlight annotation color menu will now no longer show the currently used color and has a new option "Custom..." that will show the default color picker. * The options in PSPDFEmailBarButtonItem have been changed to a bit field, it's more flexible now. The flattenedAnnotations parameter is gone and is is now a subset of the bit field. * Annotation toolbar has now properties exposed for easy drawing color/width change. * Add initial implementation for stamp annotations (text and images are supported, no complex AP streams) * Support for "Named" PDF link annotations. (like NextPage/PrevPage/FirstPage/LastPage) * Add "Key" image for note annotations. * Add support for dashed borders on various annotation types. * PSPDFPageLabelView how shows a custom label for double page mode that displays all visible pages, not only the first. (2-3 of 42) instead of (2 of 42). * Refactoring of the search subsystem. Some methods have been renamed/deprecated. The interface is now much cleaner. * Search now search pages in the natural order, no longer visible pages first. You can revert this behavior change with setting searchVisiblePagesFirst to YES in PSPDFSearchViewController. * Search now also finds words that are split up via newline and/or a hyphenations character. This is enabled by default. See PSPDFTextSearch.compareOptions. * PSPDFSearchResult now has a PSPDFTextBlock as selection type (because it might have words on multiple lines). PSPDFSearchHighlightView now supports highlighting of multiple words. * Search now is more tolerant on single/double quotation marks. * Improves annotation toolbar animation for iPhone/landscape. * PSPDFHighlightAnnotation has a new helper "highlightedString" to get the string value of the highlighted area. Here, the document content is evaluated, since the annotation just contains CGRect values. * The annotation toolbar now remembers all last used colors per annotation type IF they are changed while the annotation toolbar is visible. (e.g. create yellow highlights, change annotation color to red, make new highlights -> red. But if you change color at a point where the annotation toolbar is closed, the color will not be remembered.) * PSPDFGlyph/PSPDFWord/PSPDFTextBlock frame now needs to be converted using the convertViewRectToGlyphRect/convertGlyphRectToViewRect to get the correct results. * New helper: PSPDFBezierPathGetPoints to convert UIBezierPaths into the representation needed in PSPDFInkAnnotation. * Adds some missing annotation change events. * A visible annotation toolbar will be removed when the viewController disappears. * Improved the performance of outline parsing and animation. * New HUD mode: PSPDFHUDViewAutomaticNoFirstLastPage - similar to PSPDFHUDViewAutomatic but doesn't show the HUD on the first/last page automatically. * Delegate didRenderPage:inContext: is now only called for current rendering. (not manual calls or cache) * PSPDFAnnotationToolbar now exposes cancelDrawingAnimated/doneDrawingAnimated to manually cancel/confirm a open drawing. * PSPDFSearchBarButtonItem, PSPDFOutlineBarButtonItem, PSPDFViewModeBarButtonItem can now also be overridden using overrideClassNames. * PSPDFOutlineParsers's isOutlineAvailable now parses the outline and always returns the correct value. * If the keyboard was displayed on a PDF password prompt, that is now hidden again after the viewController is removed from the view. * A single paged document is now displayed centered on pageCurl transition mode (instead of right-aligned) * Adds the iPod touch (4G) to the list of old devices, because that one has Retina but only 256MB RAM. * Allows click-through selection of annotations that are on different pages. (before, you needed sometimes one extra-touch to hide the current selection) * PSPDFGlyph, PSPDFWord, PSPDFTextLine and PSPDFTextBlock can now be properly compared using isEqual. * The text selection is now hidden before the callout menu hides, not afterwards (to match default iOS behavior) * On the Thickness... menu, the option that is currently active is hidden. * The link selection touch-down gray is now less dark to better match Apple's default look. * The tinted popover background is now retina optimized and no longer draws an arrow outside of the rounded corner area. * Fixes a potential stack overflow when parsing really large PDF outlines (>3000 items). * Fixes an UI issue where the annotation toolbar active mode overlay wasn't updated on an annotation frame change. * Fixes an UI bug where note annotations could show with an outdated view (e.g. no color change visible on page change) * Fixes a rare crash when searching certain documents. * Fixes a rare crash regarding ink annotation saving. * Fixes an issue where tapping on an empty HUD space would sometimes wrongly zoom out the view. * Fixes some minor issues with video cover. * Fixes some settings where didLoadPageView: was not called anymore. * Fixes a rare UIKit crash in UIPageViewController by adding a workaround. * Fixes a potential crash when hot-swapping the document from/to a 1-page document while using UIPageViewController in dual page mode. * Fixes an issue where the text selection menu sometimes wasn't correctly displayed on the right site of a zoomed in page in pageCurl mode. * Fixes a potential crash when a document was hot-swapped during a render operation. * Fixes a rare rendering issue with certain PDF documents that have weird rotation values. * Fixes an issue with the CMap parser where the second part of font ligatures was ignored. (See http://en.wikipedia.org/wiki/Typographic_ligature for details) * Fixes PSPDFProcessor's output of generatePDFFromDocument on rotated PDFs (documents had white border). * Fixes a issue where parsed text coordinates were offset on some non-standard PDFs that had both rotation and a non-null CropBox origin. * Makes custom implementations of `isEqual:` commutative when called with an instance of the superclass as the argument. (#7893) KNOWN ISSUE: Annotations can't yet be moved *between* pages. This feature is on our roadmap. ## 2.4.0 — 2 Nov 2012 PSPDFKit now requires iOS 5.0+ and Xcode 4.5+ (iOS SDK 6.0) to compile. (Support for iOS 4.3/Xcode 4.4 has been removed, support for iOS 6.1 and Xcode 4.6b1 has been added.) 2.4 is a big release and a great new milestone of PSPDFKit. If you upgrade, make sure to read through the full header diffs to make sure methods you were calling/overriding still exist and are not moved. Common methods like pageScrolling will always get a compatibility method for the time being. Methods/Properties are are deeper within the framework won't get a compatibility method, but it's usually pretty easy to figure out what the property was named before. I am planning on working on PSPDFKit for a long time, and as the API evolves, it's sometimes necessary to clean up and rename things so that the API stays clean and logical. * Huge refactoring of PSPDFAnnotationParser. It's now much easier to add custom annotation providers (see PSPDFAnnotationProvider). If you have subclassed saving/loading or other parts of PSPDFAnnotationParser, you most likely need to change this over to the new PSPDFFileAnnotationProvider. * Page scrolling is now even smoother. And finally removes the slight stuttering when pushing the PSPDFViewController - now animates like butter. * PSPDFShapeAnnotation can now be saved into the PDF. * Ink drawings can now customize the Thickness. Select an annotation and use the new "Thickness..." menu item. * Ink drawings and shape annotations can now also contain comment text. * Annotations now support the title/user "T" flag. Change the default user name by changing the property in PSPDFFileAnnotationProvider. * Add support for embedded and external RichMedia and Screen (Video) annotations of any size. * PSPDFBarButtonItem now has longPress-support. Long-Press on the bookmarkBarButtonItem to see the new PSPDFBookmarkViewController. Bookmarks can now also be renamed/reordered. * If there's no searchButton visible, the search invoked from the text selection menu now will originate from the selection rect. * The Open In... action now also works on multi-file documents and/or data/cgdocumentprovider based documents (will merge the document on-the-fly, shows a progress window if it'll take some time) * PSPDFBarButtonItem now also accepts a generic UIView as sender on presentAnimated:sender:. (makes it easier to manually call menu items from custom code) * Better support when barButtonItems are added to custom UIToolbars. * The internal used BarButtonItem subclasses are now exposed, so that they can be overridden and their icon changed. * New activityBarButtonItem to share pages to Facebook/Twitter on iOS6. * Double-Tapping on a video now enables full-screen (instead of zooming the page. This does not apply to YouTube movies) * Greatly improves handling of multiple video views on one page/screen. * Annotation views now have a optional xIndex. Video has a high index by default, so link annotations won't overlap a video anymore. * No longer allowing text selection above video annotations. * PSPDFDocument now has a new property 'PDFBox' to customize the used PDF box (ClipRect/MediaRect/etc). * PSPDFPositionView has been renamed to PSPDFPageLabelView. PSPDFPageLabelView and PSPDFDocumentLabelView are now easier skinable with the common superclass PSPDFLabelView. * PSPDFLabelView has now a second predefined style (PSPDFLabelStyleBordered) * PSPDFPageLabelView can now show a toolbar item. Check out the "Settings for a magazine" example how to enable this. * PSPDFLinkAnnotationView and the other multimedia annotation views can now be subclassed via overrideClassNames. * The Edit button for the text editor on note annotations can now be hidden. (showColorAndIconOptions) * UI: Moved the Edit button of the PSPDFNoteAnnotationController to the left side. (only visible for PSPDFNoteAnnotation) * Improves annotation parsing speed. * Shape/Circle annotations now correctly display their fillColor. * Improved color parsing for PSPDFFreeTextAnnotation (now honoring the default style string setting) * The icons in the viewModeBarButtonItem now have the same shadow as the toolbar icons (iPhone for now). * No longer displays annotation menus when they can't be saved (PSPDFKit Basic) * Expose outlineIntentLeftOffset and outlineIndentMultiplicator as properties on PSPDFOutlineViewController and PSPDFOutlineCell. * Exposes firstLineRect, lastLineRect and selectionRect on PSPDFTextSelectionView. * The text loupe now fades our correctly when in drag-handle-mode. * Improved caching of external resources like annotations/text glyphs on page init. Caching now won't overflow the dispatch queues anymore if A LOT of pages are loaded at the same time. * PSPDFWord now has a lineBreaker property to detect line changes. * PSPDFPageInfo now regenerates the pageRotationTransform when the pageRotation is changed manually. * PSPDFKit now checks if a URL can be handled by the system and weird/nonrecognizable URLS no longer open the "Leave Application" alert. * The PSPDFAnnotationBarButtonItem is now smart enough to choose the right animation depending if the toolbar is at the top/bottom (slide in/out from top/bottom) * Setting the UIPopoverController no longer removes preexisting passthroughViews. * The renderQueue now no longer renders the requested image if the delegate has been released in the mean time. (The delegate is now weak instead of strong) * UI: Undo/Redo buttons on the drawing toolbar are better placed on iPhone. * UI: The color selection button is now smaller on iPhone/Landscape. * API: PSPDFPageInfo is not calculated in PSPDFDocumentProvider. If you've overridden methods that affect PSPDFPageInfo in PSPDFDocument, you should move that code to a PSPDFDocumentProvider subclass. * API: "realPage" has been renamed to "page" and is now set-able. The old "page" has been renamed to "screenPage". This finally cleans up the confusion that has been around page and realPage. In 99% of all cases, you're just interested in page and can ignore screenPage. Please update your bindings accordingly. If you formerly did KVO on realPage, change this to page too. (There's a deprecated compatibility property for realPage, but not for the KVO event) * API: additionalRightBarButtonItems has been renamed to additionalBarButtonItems. * API: pageScrolling has been renamed to scrollDirection. A deprecated compatibility call has been added. * API: handleTouchUpForAnnotationIgnoredByDelegate has been moved to PSPDFAnnotationController. * API: pdfViewController has been renamed to pdfController on PSPDFTabbedViewController. * API: Warning! If you've used pspdf_dispatch_sync_reentrant in your own code, you now absolutely must create your dispatch queues with pspdf_dispatch_queue_create. Apple has deprecated dispatch_get_current_queue(), so we're now using a different solution. This will most likely affect you if you're using the "Kiosk" sample code of PSPDFKit Catalog. * Titanium: The pdfView now has a hidePopover(true) method so PSPDF popovers can better be coordinated with appcelerator code popovers. * Fixes the lag introduced in 2.3.x when tapping on the screen and the textParser hasn't been finished yet. * Fixes a potential crash when the view was removed on PSPDFKit Basic Titanium. * Fixes a potential crash when parsing the text of malformed PDFs. * Fixes a race condition during PSPDFFreeTextAnnotation drawing that could lead to a crash. * Fixes some issues with PSPDFPageScrollContinuousTransition when the document is invalid or view size is nil. * Fixes an issue where the background color of link annotations could get stuck. * Fixes an issue where PSPDFTabbedViewController did not properly align the tab bars in fullscreen mode. * Fixes an issue with creating PSPDFShapeAnnotation in code. * Fixes an issue where the isEditable flag on a PSPDFAnnotation was not honored when dragging note annotations. * Fixes an issue where the page could disappear on strong scrolling in pageCurl mode under iOS6. * Fixes an issue where scrolling on the tab bar (PSPDFTabbedViewController) sometimes didn't work. * Fixes an issue where the color picker was not properly displayed on bottom UIToolbars. * Fixes an UI issue where the selection and drawing of annotations on rotated pages was handled incorrectly. * Fixes an UI issue where the tabbed controller tabs could be mis-placed when rotating without visible HUD. * Fixes an UI issue where the thumbnails could slightly overlap the toolbar if the statusbar is transparent/auto-hiding. * Fixes several conditions where the PSPDFViewController could be deallocated on a background thread. * Fixes new warnings that popped up with Xcode 4.6. (pretty much all false positives) ## 2.3.4 — 18 Oct 2012 * Fixes a rare race condition that could lead to a deadlock on initializing PSPDFDocumentProvider and PSPDFAnnotationParser. ## 2.3.3 — 18 Oct 2012 Note: This will be the last release that supports iOS 4.3*. The next version will be iOS 5+ only and will require Xcode 4.5+ (iOS SDK 6.0) If you're having any comments on this, I would love to hear from you: pspdfkit@petersteinberger.com The binary variant is already links with SDK 6.0 and will not link with 5.1 anymore. (It still works down to iOS 4.3 though) (*) There is no device that supports iOS 4.3 and can't be upgraded to iOS5, and PSPDFKit already dropped iOS4.2 and with it armv6 in 2.0. * PSPDFShapeAnnotation and PSPDFLineAnnotation can now be created programmatically. * New flag: kPSPDFLowMemoryMode that combines a lot of settings to ease memory pressure for complex apps. * Annotations now have a new flag: controls:false to hide browser/movie controls. If videos have controls disabled, they can be controlled via gestures. (tap=pause, pinch=full screen) * Text loupe now also moves if it's not anchored on a PSPDFPageView. (fixes stuck loupe issue) * Fixes a regression on view point restoration that could restore the view point at a different position. * Fixes an issue where the annotation toolbar could lock up rotation even after being dismissed. * Fixes an issue where bookmarks were checked for pages that were not visible. * Fixes the needless log statement "Password couldn't be converted to ASCII: (null)". * Fixes a text loupe regression where the loupe was not rotated on modal controllers. * Fixes a issue where in rare cases the document label (default displayed on iPhone only) was offset by a few pixels. ## 2.3.2 — 17 Oct 2012 * The text loupe is now displayed above all other contents (navigation bar, status bar, …) * New status bar style: PSPDFStatusBarSmartBlackHideOnIpad, which now is also the new default (changed from PSPDFStatusBarSmartBlack). Will hide the HUD AND the statusbar on tap now both on iPhone and on iPad. * Improves Website->PDF conversion. Now supports Websites, Pages, Keynote, Excel, Word, RTF, TXT, JPG, etc... (see PSPDFProcessor. This is a PSPDFKit Annotate feature) * PSPDFKit now uses the MediaBox everywhere. Previously the CropBox was used for rendering, which can display areas that are only intended for printing. See http://www.prepressure.com/pdf/basics/page_boxes. * New additionalActionsButtonItem allowing the selection of the additional actions menu placement position. (Default is left next to the last rightBarButtonItem) * New initializer in PSPDFDocument that makes handling with single-file multiple-page documents much easier. (PDFDocumentWithBaseURL:fileTemplate:startPage:endPage:) * Add support for GoToR link annotations. * Add method to search for a specific page label. See PSCGoToPageButtonItem in PSPDFKit Catalog for an example how to use it. (DevelopersGuide.pdf has labels) * The page popover now shows the page label if one is set in the PDF (e.g. to replace numbers with roman numbering) * Links to the external applications (e.g. AppStore, Mail) are now detected and a alert view is displayed asking to open the application or not. * Add workaround for a UIKit issue in iOS5.x that would sometimes dismiss the keyboard when removing characters from the search view controller. (Issues has been fixed in iOS6) * Fixes a UI issue in search results. If a search result was found more than one time in a string, the first occurrence was marked bold. Now the actual result is marked bold. (This was mostly noticeable when searching for very small words) * Fixes a issue where too fast drawing could result in some lines now being displayed. * Fixes isLastPage/isFirstPage methods for landscape mode. * Fixes a issue where sometimes overrideClassNames for annotation was ignored. * Fixes a issue where the cache could return a wrong image in some rare cases. ## 2.3.1 — 11 Oct 2012 * Fixes a potential memory corruption with PSPDFAESCryptoDataProvider. ## 2.3.0 — 11 Oct 2012 * Experimental features: Add support to create PDF documents from html string or even a website. * Annotations now can be flattened before the document is sent via email. PSPDFEmailBarButtonItem has new options, and there is a new class PSPDFProcessor to generate new PDFs. * Outline elements that have no target page now no longer redirect to page 1 and will expand/collapse a section if there are child outline elements. * Add minimumZoomScale and setZoomScale:animated: to PSPDFViewController. * Glyphs that are outside of the page rect are now not displayed in the extracted text per default. You can restore the old behavior with setting PSPDFDocument's textParserHideGlyphsOutsidePageRect to YES. * Further tweaks for the iOS5 YouTube plugin version, ensure it's always correctly resized. * viewLockEnabled now also disables zooming with double tapping. * Don't show outline on search result if it's just one entry (most likely just the PDF name) * The keyboard of the note annotation controller now moves out at the same time as the popover dismisses (before keyboard animated out AFTER the popover animation) * Software dimming view now also covers the status bar. * Adding/Removing bookmarks now correctly hides any open popovers. * PSPDFKit Catalog: can now receive PDF documents from other apps. * PSPDFKit Catalog: added basic full-text-search feature across multiple documents. * Removed kPSPDFKitDebugMemory and kPSPDFDebugScrollViews. * API: renamed PSPDFSearchDelegate -> PSPDFTextSearchDelegate and added the PSPDFTextSearch class as parameter. * API: removes certain deprecated methods. * API: renamed kPSPDFKitPDFAnimationDuration to kPSPDFAnimationDuration. * Fixes possible inconsistency between displayed and used drawing color. * Fixes a race conditions when using appendFile: in PSPDFDocument and cacheDocument:startAtPage:size:. * Fixes a rotation issue when the annotation toolbar is displayed. * Fixes a issue where the popover of a ink annotation wasn't correctly sized. * Fixes a issue where the outline button was displayed when the document was invalid (instead of being hidden as expected) ## 2.2.2 — 5 Oct 2012 * Properly restore the PSPDFLinkAnnotationView backgroundColor. ## 2.2.1 — 4 Oct 2012 * The original backgroundColor of a PSPDFLinkAnnotationView is now preserved. * YouTube embedding now supported on iOS6. * Video embeddings with a cover image now don't show the cover if play has already been pressed after a page change. * Annotations now are cached much like UITableViewCells. (faster; preserve video state, etc) * Fixes a "sticky" scrolling issue that was introduced in 2.2. ## 2.2.0 — 4 Oct 2012 * New scrolling mode: PSPDFPageScrollContinuousTransition (similar to UIWebView's default mode) * Support text selection on rotated PDF documents. * UIPopoverController is now styleable with a tintColor. This is enabled by default if tintColor is set. Use.shouldTintPopovers to disable this. As long as you use presentViewControllerModalOrPopover:embeddedInNavigationController:withCloseButton:animated:sender:options: your custom popovers will be styled the same way. * Adds support for adding annotations for double page mode on the right page. (Note: drawing still isn't perfect) * Add new property renderAnnotationTypes to PSPDFViewController to allow control about the types of annotations that should be rendered. * Add support for PDF Link Launch annotations (link to a different PDF within a PDF, see https://www.nutrient.io/guides/ios/annotations/link-annotations/) * Annotation selection is now smarter and selects the annotation that's most likely chosen (e.g. a small note annotation now is clickable even if it's behind a big ink drawing annotation) * It's now possible to properly select an annotation while in highlight mode. * Allow changing the drawing color using the menu. (invokes the color picker) * Add a isEditable property to be able to lock certain annotations against future edits. * Add printing support for small CGDataProviderRef-based PSPDFDocuments. * Improve OpenIn… feature, annotations are auto-saved before opening in another app and a log warning will be displayed for incompatible document compositions. * The password in PSPDFDocument is now saved and will be relayed to any added file (e.g. when using appendFile) * Improved performance for outline and annotation parsing (up to 400% faster, especially for large complex documents with huge outlines) * Massively improved performance for search, especially for documents with many fonts. * Text loupe is faster; less delays on the main thread when waiting for a textParser (more fine-grained locking) * PSPDFViewController now saves any unsaved annotation data when app moves to background. * Add PSPDFBrightnessBarButtonItem and optional software-dimming to darken the screen all the way down to black. * PSPDFDocuments objectsAtPDFRect:page:options: now can also search for annotations and text blocks. * Smart Zoom is now even smarter and picks the most likely tapped text block if the detection shows multiple overlaying blocks. * Adds Italian translation. * Restores PDF page label feature from version 1. * removeCacheForDocument:deleteDocument:error: now also removes any document metadata files (bookmarks, annotations [if they were saved externally]) * The cancel button in PSPDFSearchViewController can now be localized. * PSPDFKit now uses UICollectionView on iOS6, and PSTCollectionView on iOS4/5. * When annotations are deserialized from disk, the proper annotation subclasses set in document.overrideClassNames will be used. * Ensure annotation toolbar is closed when view controller pops. * Thumbnails no longer are laid out behind the tab bar if PSPDFTabbedViewController is used. (they now correctly align beneath the bar) * Add workaround for a UIKit problem where a UIPopoverController could be resized to zero on iPad/landscape when it's just above the keyboard. * Greatly reduced the black hair line that was visible in double page modes between the pages. Should now be invisible in most cases. * The last used drawing color is now saved in the user defaults. * The bookmark image is now saved proportionally to the thumbnail image. * Ensures that for PSPDFTabbedViewController, tabs always have a title. * The close button added when using the presentModal: api of PSPDFViewController now uses the Done-button style. * API: bookmark save/load now exposes NSError object. Also new; clearAllBookmarks. * API: willStartSearchOperation:forString:isFullSearch: in PSPDFSearchOperationDelegate is now optional. * API: PSPDFDocument now implements PSPDFDocumentProviderDelegate and also is set as the default delegate. * API: PSPDFDocumentDelegate now has methods for didSaveAnnotations and failedToSaveAnnotations. * API: removeCacheForDocument:deleteDocument:waitUntilDone: is now removeCacheForDocument:deleteDocument:error: - * Fixes a rotation issue when the annotation toolbar is displayed use dispatch_async to make the call async. * API: tabbedPDFController:willChangeVisibleDocument: has been renamed to tabbedPDFController:shouldChangeVisibleDocument: * Fixes a bug where annotations were not saved correctly on multi-file documents when saving into external file was used. You need to delete the annotations.pspdfkit file in /Library/PrivateDocuments/UID to update to the new saving version (PSPDFKit still first tries to read that file to be backwards compatible) * Fixes freezing if there are A LOT of search results. They are not limited to 600 by default. This can be changed in PSPDFSearchViewController, see maximumNumberOfSearchResultsDisplayed. * Fixes a issue where similar PDF documents could create a equal UID when initialized via NSData. * Fixes "jumping" of the annotation toolbar when the default toolbar style was used. * Fixes calling the shouldChangeDocuments delegate in PSPDFTabbedViewController. * Fixes issue with rotation handling under iOS6. * Fixes a bug that prevented selecting annotations for documents with multiple files on all but the first file * Fixes a bug where the text editor sometimes could have a transparent background. * Fixes a toolbar bug when using UIStoryboard and modal transitions to PSPDFViewController. * Fixes a rare placement bug with the document title label overlay on iPhone. * Fixes a regression of 2.1 where search on iPhone sometimes didn't jump to the correct page. * Fixes issue with certain unselectable words. * Fixes always-spinning activity indicator when internal WebBrowser was closed while page was still loading. ActivityIndicator management now also can be customized and/or disabled. * Fixes a page displacement issue with pageCurl and the app starting up in landscape, directly showing a PSPDFViewController. (workaround for a UIKit issue; has been fixed in iOS6) * Fixes invalid page coordinates sent to didTapOnPageView:atPoint: delegate on right page in landscape mode. * Fixes a race condition where annotations could be missing on display after repeated saving until the document has been reloaded. * Fixes issue with word detection where sometimes words were split apart after the first letter on the beginning of a line. * Fixes viewState generation. (Was always using page instead of realPage which lead to errors when using landscape mode) * Fixes missing background drawing for shape annotations. * Fixes a issue where certain link-annotations did not work when using the long-press and then tap on the sheet-button way. * Fixes a rare bug where pages could been missing when reloading the view of the PSPDFPerPageScrollTransition in a certain way. * Fixes issue where viewLockEnabled was ignored after calling reloadData. Known Issues: * Dragging note annotations from one page to another doesn't yet work. * Drawing across multiple pages doesn't yet work. ## 2.1.0 — 17 Sep 2012 * New: PSPDFAESCryptoDataProvider. Allows fast, secure on-the-fly decryption of AES256-secured PDF documents. (PSPDFKit Annotate feature) Unlike NSData-based solutions, the PDF never is *fully* decrypted, and this even works with very large (> 100MB) documents. Uses 50.000 PBKDF iterations and a custom IV vector for maximum security. Includes the AESCryptor helper Mac app to properly encrypt your PDF documents. * Allow to customize caching strategy per document with the new cacheStrategy property. This is automatically set to PSPDFCacheNothing when using PSPDFAESCryptoDataProvider. * Annotations now have a blue selection view when they are selected. * Add Black and Red to general annotation color options. * Font name/size for FreeText annotations is now parsed. * Added write support for FreeText annotations. * Allow to show/edit the associated text of highlight annotations. * Improves extensibility of the annotation system with adding a isOverlay method to PSPDFAnnotation. (Instead of hard-coding this to Link and Note annotations) * Moves the clipsToBounds call in PSPDFPageView so that delegate can change this (of UIView ). * Adds static helper [PSPDFTextSelectionView isTextSelectionFeatureAvailable] to make runtime checks between PSPDFKit and PSPDFKit Annotate. * Adds new isWriteable static method to PSPDFAnnotation subclasses to determine what classes can be written back to PDF. * Add kPSPDFAllowAntiAliasing as optional render option. * PSPDFOpenInBarButtonItem no longer performs a check for compatible apps. Checking this is pretty slow. An info alert will be displayed to the user if no compatible apps are installed (which is highly unlikely for PDF). You can restore the original behavior with setting kPSPDFCheckIfCompatibleAppsAreInstalled to YES. * The viewState is now preserved when another controller is displayed/dismissed modally. This mostly happened with showing/hiding the inline browser or the note text controller on an iPhone. After that the zoom rate was reset; this is now properly preserved. * The annotation toolbar now flashes if the user tries to hide the HUD while the bar is still active (and blocking that) * Various performance optimizations; especially scrolling and initial controller creation. * Removes sporadic vertical transition of the navigationController's navigationBar when HUD faded out. * Fixes "Persistent Text Loupe" when moving over a link annotation while selecting. * Fixes a memory leak when CGDataProviderRef is used to initialize a PSPDFDocument. * Fixes a issue where the UI could sometimes freeze for a while waiting for background tasks in low-memory situations. * Fixes a issue where the popover page display wasn't hidden after a rotation. * Fixes a issue where sometimes the page was not correctly restored after rotation (was +1). * Fixes a issue where, if email wasn't configured on the device, the internal web browser would be launched with a mailto: link. Now a alert is displayed. * Fixes a issue where a page could, under certain rare conditions, escape the page tracking and be "sticky" behind the new managed page views. * Titanium: Add saveAnnotation method to manually save annotations (needed for createView, automatically called in showPDFAnimated). * Titanium: Limit usage of useParentNavigationBar to iOS5 and above. * Titanium: fixes a rare condition where using document.password to unlock sometimes resulted in an incorrect value for isLocked. ## 2.0.3 — 14 Sep 2012 * Add a new "renderOptions" property to PSPDFDocument to fine-tune documents (e.g. fixes gray border lines in mostly-black documents) * Reduces file size of PSPDFKit.bundle by about 50%; improves speed of certain helper plists parsing. * Fixes potential category clashing * Fixes a bug that sneaked in because PSPDFKit is now compiled with Xcode 4.5. This release now also works with 4.4 for binary. ## 2.0.2 — 13 Sep 2012 * Support for iPhone 5, Xcode 4.5, armv7s and the new screen resolution. * Supports a new cover property to have a custom cover screen for videos (big play button; custom preview-images) * Don't show browse popover/actionsheet for multimedia extensions during a long press. * Don't allow long-press over a UIControl. (e.g. a UIButton) * Fixes a issue where sometimes multimedia annotations would be added multiple times to the document. * Fixes a issue where sometimes you get blank space instead of a page when PSPDFPageRenderingModeFullPageBlocking and PSPDFPageScrollPerPageTransition was combined and the scrobble bar used heavily. This is a workaround for a UIKit bug. * Removes libJPGTurbo; Apple's own implementation has gotten faster (especially in iOS6) ## 2.0.1 — 12 Sep 2012 * Faster search (document pattern detection if delayed until needed, outline results get cached) * Improved reaction time for complex PDF documents (e.g. annotations are only evaluated if they're already loaded; but won't lock the main thread due to lazy parsing) * Add additional checks so that even incorrectly converted NSURL-paths (where description instead of path has been called) work. * Fixes a issue where annotations were not saved with multiple-file documents on all but the first file. * Fixes problems where link annotations lost their page/link target after saving annotations into a file. * Fixes a problem where fittingWidth was always overridden when run on the iPhone. * Fixes a race condition in the new render stack that could lead to an assert in debug mode (non-critical) * Fixes the toolbar overlapping text issue in the PSPDFKit Catalog Kiosk Example; added comments how to work around that UIKit bug. * Made the pageRotation property of PSPDFPageInfo writeable; useful for manually rotation PDF documents. * Fixes some issues with the Titanium module; adds support for NavigationGroups. * Improved memory usage, especially on iPad1. ## 2.0.0 — 8 Sep 2012 PSPDFKit 2 is a major updates with lots of changes and a streamlined API. There are some API deprecations and some breaking changes; but those are fairly straightforward and well documented. You need at least Xcode 4.4.1 to compile. (Xcode 4.4/4.5 both run fine on Lion, Mountain Lion is not needed but recommended) PSPDFKit 2 is compatible with iOS 4.3 upwards. (armv7, i386 - thus dropping iOS 4.2/armv6 from version 1) The installation has been simplified. You now just drop the "PSPDFKit.embeddedframework" container into your project. Next, enable the PSPDFKit.xcconfig project configuration. Here's a screenshot: http://cl.ly/image/1e1I2Z2e1D3F (Select your project (top left), select project again in the PROJECT/TARGETS tree, select Info, then change in "Based on Configuration file" from None to PSPDFKit.) If you have the sources and embed PSPDFKit as a subproject, don't forget to also add PSPDFKit.bundle. MAJOR NEW FEATURES: * Text selection! (PSPDFKit Annotate) (Includes Copy, Dictionary, Wikipedia support) * Annotations! (PSPDFKit Annotate) Highlight, Underscore, Strikeout, Note, Draw etc. Annotations also will be written back into the PDF. There is a new annotationBarButtonItem that shows the new annotation toolbar. * Smart Zoom (Text blocks are detected and zoomed onto on a double-tap; much like Safari) The PDF is now also dynamically re-rendered at *every* zoom level for maximal sharpness and quality. * Customizable render modes (enable/disable use of upscaled thumbnails). PSPDFPageRenderingModeFullPageBlocking is great for magazines. * Greatly improved Search. Faster, parses more font styles, compatible with international characters (chinese, turkish, arabic,...) * Site Bookmarks (see bookmarksBarButtonItem and PSPDFBookmarkParser) * Support for VoiceOver accessibility (yes, even within the PDF!) Further, PSPDFKit has been improved in virtually every area and a lot of details have been tweaked. * Inline password view. (Before, just a empty screen was shown when document wasn't unlocked.) * Adobe DRM detection (They are just marked as not viewable, instead of showing garbage) * PDF rendering indicator. (see pdfController.renderAnimationEnabled) * Even better view reuse. PSPDFPageView is now reused, scrolling is even smoother. * PSPDFDocument can now be initialized with a CGDataProviderRef or a dataArray. * The search/outline controllers now dynamically update their size based on the content height. * The Table of Contents/Outline controller now shows titles in multiple lines if too long (this is customizable) * Support for Table Of Contents (Outline) linking to external PDF documents. * Page Content/Background Color/Inversion can now be changed to modify rendering. * On the iPhone, a new documentLabel shows the title. (the navigationBar is too small for this) * PSPDFScrobbleBar now uses the small height style on iPhone/Landscape. * PSPDFViewController can now programmatically invoke a search via searchForString:animated:. * PSPDFViewController now has a margin and a padding property to add custom margin/padding on the pdf view. * PSPDFViewController now has a HUDViewMode property to fine-tune the HUD. * PSPDFTabbedViewController now has a minTabWidth property (defaults to 100) * It's now possible to pre-supply even fully-rendered page images. PSPDFDocument's thumbnailPathForPage has been replaced with cachedImageURLForPage:andSize:. * PSPDFDocument now has a overrideClassNames dictionary, much like PSPDFViewController. * PSPDFDocument now has objectsAtPDFPoint/objectsAtPDFRect to return found glyphs and words. * PSPDFDocument now has convenience methods to render PDF content. (renderImageForPage:withSize:.../renderPage:inContext:...) * PSPDFDocument now exposes some more common metadata keys for the PDF metadata. * PSPDFDocument now has convenience methods to add and get annotations (addAnnotations:forPage:) * PSPDFDocument now has a property called annotationSaveMode to switch between PDF annotation embedding or an external file. * Support for documents with multiple sources(files/dataArray/documentProvider) is now greatly improved due to the new PSPDFDocument/PSPDFDocumentProvider structure. * PSPDFPageView now has convenience methods to calculate between PDF and screen coordinate space (convertViewPointToPDFPoint/convertPDFPointToViewPoint/etc) * PSPDFPageView no longer uses CATiledLayer; this has been replaced by a much faster and better custom solution. * PSPDFScrollView no longer accepts a tripple-tap for zooming out; this was a rarely-used feature in iOS and it increased the reaction time for the much more used double tap. Zooming in/out is now smarter (smart zoom) and does the right thing depending on the zoom position. * PSPDFWebViewController now supports printing. * A long-press on a PDF link annotation now shows the URL/Document/Page target in a popover. * When switching between DEMO/FULL; the change is automatically detected and the cache cleared. (No more watermark problems) * The image annotation view now properly displays and animates animated GIFs. * GMGridView has been replaced by the new and better PSCollectionView, which is a API compatible copy of UICollectionView. * Internal modernization; literals, subscripting, NS_ENUM, NS_OPTIONS. * Better internal error handling; more functions have error parameters. Fixes/API changes: * The navigationBar title is no longer set on every page change. * PSPDFDocument's PDFDocumentWithUrl has been renamed to PDFDocumentWithURL. * Delegates are now called correctly (only once instead of multiple times) in pageCurl mode. * pdfViewController:willShowController:embeddedInController:animated: has been changed to (BOOL)pdfViewController:*SHOULD*ShowController:embeddedInController:animated: * tabbedPDFController:willChangeDocuments has been renamed to tabbedPDFController:shouldChangeDocuments. * New delegate: - (void)pdfViewController:(PSPDFViewController *)pdfController didEndPageDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate withVelocity:(CGPoint)velocity targetContentOffset:(inout CGPoint *)targetContentOffset -> completes dragging delegates; zooming delegates were already available in PSPDFKit 1. * Changed willShowController... delegate to shouldShowController... that returns a BOOL. * Fixes a problem in the annotation parser where some named page links failed to resolve properly. * Fixes a problem where the Cancel button of the additionalBarButtonItem menu wasn't fully touch-able on iPhone. * Fixes a problem with PSPDFBarButtonItem image updating. * Lots of other minor and major changes. ## 1.10.5 — 1 Aug 2012 * Add a workaround for unusable back button in a certain unreleased version of iOS. (This is most likely a temporal iOS bug) * Improve PSPDFCloseBarButtonItem to be context-aware if we should close a modal view or pop from the navigation stack. * Fixes a issue where zooming was difficult on pages with lots of PDF link annotations. * Fixes two harmless warnings with Xcode 4.4. * Fixes the delete all tabs action sheet in the TabbedExample on iPhone. * Fixes a certain issue with embedding PSPDFViewController. * Fixes a rare memory leak when image decompression fails. ## 1.10.4 — 12 Jul 2012 * New delegates: shouldScrollToPage, resolveCustomAnnotationPathToken. * If annotation is set to a file and this file doesn't exist, annotation type will be set to undefined. * Improve tap change speed and touch area of PSPDFTabbedViewController. * Another possible bugfix for UIPageViewController rotation changes. * Don't change navigationController if embedded into a parentViewController on default. (See useParentNavigationBar). * Allow to subclass PSPDFPageView via the overrideClassNames property in PSPDFViewController. * Allow parsing of PDF outlines with party invalid information. * Removed preloadedPagesPerSide. Changing this turned out to not bring any noticeable performance benefits. * Fixes a case where some link annotations were not correctly parsed. ## 1.10.3 — 22 Jun 2012 * New property in PSPDFCache: downscaleInterpolationQuality (to control the thumbnail quality) * Add some improvements to caching algorithm, adds cacheThumbnailsForDocument to preload a document. * Ensures that email attachments will end with ".pdf". * Clear annotation cache in low memory situations. Helps for documents with lots of embedded videos. * Fixes a UI issue where the transition between content and thumbnails was sometimes incorrect on zoomed-in content. * Fixes a bug where the pageIndex on thumbnails are off-by-one. * Fixes a bug where annotationEnabled wasn't correctly restored when using NSCoding on PSPDFDocument. * Fixed a problem where delegates where called too often for the initial reloadData event. * Fixes a potential crash on low-memory situations. * Fixes a potential crash with pageCurl mode and device rotations. * Fixes a crash when using a NSData-provided PSPDFDocument with no metadata title and using the sendViaEmail feature. * Fixes a issue with MPMoviePlayer disappearing during fullscreen-animation. ## 1.10.2 — 5 Jun 2012 * New controller delegates: willShowViewController:animated: and didShowViewController:animated:. * New HUD visibility delegates: shouldShowHUD/shouldHideHUD/willShowHUD:/didShowHUD:/willHideHUD:/didHideHUD: * PageLabel on thumbnails is now width-limited to the maximal image size. * The default linkAction is now PSPDFLinkActionInlineBrowser (changed from PSPDFLinkActionAlertView). * The openIn action is now displayed in the iOS Simulator, but a UIAlertView shows that this feature only works on a real device. * PSPDFOutlineElement now implements NSCopying and NSCoding. * Page labels now work with documents containing multiple files. * Removed the searchClassName property in PSPDFSearchViewController. Use the overrideClassNames in PSPDFViewController to change this. * Renamed showCancel to showsCancelButton in PSPDFSearchViewController. * searchBar in PSPDFSearchViewController is now created in init, not viewDidLoad (so you can easily customize it) * Added new API items for PSPDFTabbedViewController and changed the API to initialize the controller. (You can also just use init) * On PSPDFDocument.title, the ".pdf" ending is now automatically removed. * New property in PSPDFViewController: loadThumbnailsOnMainThread. (Moved from PSPDFPageView, new default is YES) * Fixes a short black gap when loading the document under certain conditions w/o pageCurl-mode. * Fixes a bug where the new pdf path resolving function sometimes returned invalid strings. * Fixes a bug where changing left/rightBarButtonItems needed an additional call to updateToolbar to work. This is now implicit. * Fixes a bug where nilling out left/rightBarButtonItems after the controller has been displayed didm't correctly update the navigationBar. * Fixes a bug where the position of the initial page view could be smaller than the view in landscape mode. * Fixes a bug where the titleView wasn't used to calculate the toolbarWidths. * Fixes a bug where the TabbedViewController's selected tab wasn't correctly updated when setting visibleDocument. * Fixes a bug where the TabbedViewController-preference enableAutomaticStatePersistence wasn't always honored. ## 1.10.1 — 29 May 2012 * Improvement: Better handle toolbar buttons when a too long title is set. (now exposing minLeftToolbarWidth, minRightToolbarWidth) * Improvement: sometimes the NavigationBar was restored even if it wasn't needed. * Improvement: Don't reload frame if we're in the middle of view disappearing. * Improvement: Use default white statusBar with inline browser on iPhone. * Improves the document<->thumbnail transition with certain non-uniformed sized documents and pageCurl mode. * Fixes a case where the PSPDFPositionView wasn't correctly laid out. * Fixes a problem where the close button was disabled when no document was set. * Fixes a regression regarding pageCurl mode and activated isFittingWidth. * Fixes a regression regarding the viewModeButtonItem not being displayed correctly on appcelerator. * Fixes a problem where under certain conditions a landscape->portrait rotation in pageCurl mode on the last page performed a scroll to the first page. * Fixes a leak in PSPDFActionSheet. ## 1.10.0 — 25 May 2012 This will probably be the last major release in the 1.x branch. Work on 2.x is already underway, with a focus on text selection and annotations. This release has some API-breaking changes: * New toolbar handling (breaking API change) The properties searchEnabled, outlineEnabled, printEnabled, openInEnabled, viewModeControlVisible have been replaced by a much more flexible system based on the PSPDFBarButtonItem class. For example, to add those features under the "action" icon as a menu, use this: self.additionalRightBarButtonItems = [NSArray arrayWithObjects:self.printButtonItem, self.openInButtonItem, self.emailButtonItem, nil]; If you're looking to e.g. remove the search feature, set a new rightBarButtonItems array that excludes the searchButtonItem. Likewise, the functions additionalLeftToolbarButtons, magazineButton and toolbarBackButton have been unified to self.leftBarButtonItems. If you want to replace the default closeButton with your own, just create your own UIBarButtonItem and set it to self.leftBarButtonItems = [NSArray arrayWithObject:customCloseBarButtonItem]; * Resolving pdf link paths has changed. (breaking API change) Previously, if no marker like "Documents" or "Bundle" was found, we resolved to the bundle. This version changes resolving the link to the actual position of the pdf file. If you need the old behavior, you can set PSPDFResolvePathNamesEnableLegacyBehavior to YES or use a custom subclass of the PSPDFAnnotationParser. * New class PSPDFTabbedViewController, to show multiple PSPDFDocuments with a top tab bar. iOS5 only. (includes new TabbedExample) * New feature: PDF page labels are parsed. (e.g. roman letters or custom names; displayed in the PSPDFPositionView and the thumbnail label) * New feature: send via Email: allows sending the pdf as an attachment. (see emailButtonItem in PSPDFViewController) * New feature: PSPDFViewState allows persisting/restoring of a certain document position (including page, position, zoom level). See documentViewState and restoreDocumentViewState:animated: in PSPDFViewController. * Add support for puny code characters in pdf URLs (like http://➡.ws/鞰齒). This uses the IDNSDK. * New property: useParentNavigationBar, if you embed the PSPDFViewController using iOS5 containment and still want to populate the navigationBar. * New property: pageCurlDirectionLeftToRight to allow a backwards pagination. (for LTR oriented documents) * New delegate: delegateDidEndZooming:atScale to detect user/animated zooming. * UI Improvement: Show URL in embedded browser title bar, until page is loaded with the real title. * General: Add french localization in PSPDFKit.bundle. * Core: PSPDFDocument now implements NSCopying and NSCoding protocols. * Fixes a problem where links with hash bangs (like https://twitter.com/#!/) where incorrectly escaped. * Fixes opening certain password protected files. * Fixes unlockWithPassword always returning YES, even with an incorrect password. * Fixes a crash regarding pageCurl and UpsideDown orientation on the iPhone. * Fixes a problem where the search delegates where called after canceling the operation. * Fixes a problem where the page wasn't re-rendered if it was changed while zoom was active. * Fixes a problem where the tile wasn't updated after setting document to nil. * Fixes a problem where under rare conditions a spinlock wasn't released in PSPDFGlobalLock. * Adds support for Xcode 4.4 DP4. Due to an already acknowledged Apple linker bug. Xcode 4.4 DP5 is currently broken. (Xcode 4.3.2 is still recommended) * Titanium: New min SDK is 2.0.1.GA2. ## 1.9.15 — 20 Apr 2012 * New delegate: pdfViewController:didEndPageScrollingAnimation: to detect if a scroll animation has been finished. This will only be called if scrollToPage:animated: is used with animated:YES. (not for manual user scrolling) * Additional safeguards have been put in place so that videos don't start playing in the background while scrolling quickly. ## 1.9.14 — 20 Apr 2012 * Adds support for Xcode 4.4 DP3. * Show document back button even if PSPDFViewController is embedded in a childViewController. * Doesn't try to restore the navigation bar if we're the only view on the navigation stack. * Allow PSPDFSearchHighlightView to be compatible with overrideClassNames-subclassing. * Works around some broken annotations that don't have "http" as protocol listed (just www.google.com) * PSPDFPageView now has convertViewPointToPDFPoint / convertPDFPointToViewPoint for easier annotation calculation. * There are also some new PSPDFConvert* methods in PSPDFKitGlobal that replace the PSPDFTiledView+ categories. (API change) * YouTube embeds finally support the autostart option. (Note: This might be flaky on very slow connections) * Fixes a big where some documents would "shiver" due to a 1-pixel rounding bug. * Fixes a regression with KVO-observing viewMode. * Fixes a UI glitch with animated pageScrolling on pageCurl if invoked very early in the view build hierarchy. * Fixes a problem where video was playing while in thumbnail mode. ## 1.9.13 — 7 Apr 2012 * Zooming out (triple tap) doesn't scroll down the document anymore, only moves the zoom level to 1.0. * Better handling of light/dark tintColors. * ScrobbleBar is now colored like the navigationBar. (check for HUD changes/regressions in your app!) * The status bar now moves to the default color on the iPhone for ToC/Search views. * Fixes an alignment problem with the thumbnail animation. * Disable user interaction for very small links, that are not shown anyway. * YouTube videos now rotate and resize correctly. ## 1.9.12 — 2 Apr 2012 * Thumbnails now smoothy animate to fullscreen and back. (new setViewMode animation instead of the classic fade) * Fullscreen video is now properly supported with pageCurl. (with the exception of YouTube) * Annotation views are now reused -> better performance. * The outline controller now remembers the last position and doesn't scroll back to top on re-opening. * Hide HUD when switching to fullscreen-mode with videos. * Don't allow touching multiple links at the same time. * Transition between view modes are now less expensive and don't need view reloading. Also, zoom value is kept. * The pageInfo view now animates. (Page x of y) * The grid now properly honors minEdgeInsets on scrolling. * Thumbnail page info is now a nice rounded label. * Fixes partly missing search highlighting on the iPhone. * Fixes a few calculation errors regarding didTapOnPageView and the PSPDFPageCoordinates variable. * Fixes a problem where caching sometimes was suspended and got stuck on old devices. * Free more memory if PSPDFViewController is not visible. ## 1.9.11 — 28 Mar 2012 * Add more control for pageCurl, allows disabling the page clipping. (better for variable sized documents) * New method on PSPDFDocument: aspectRatioVariance. Allows easy checks if the document is uniformly sized or not (might be a mixture of portrait/landscape pages) There is example code in PSPDFExampleViewController.m that shows how this can be combined for dynamic view adaption. * Support for Storyboarding! You can create a segway to a PSPDFViewController and even pre-set the document within Interface Builder. There now is a new example called "StoryboardExample" that shows how this can be used. (iOS5 only) * Note: if you use IB to create the document, you just use a String. Supported path expansions are Documents, Cache, Bundle. Leave blank for Bundle. * Changes to navigationBar property restoration - now animates and also restores alpha/hidden/tintColor. Let me know if this breaks something in your app! * Fixes a potential crash with a controller deallocation on a background thread. * Fixes a potential crash when searching the last page in double page mode. * Fixes a regression introduced in 1.9.10 regarding a KVO deallocation warning. ## 1.9.10 — 26 Mar 2012 * Greatly improved performance on zooming with the new iPad (and the iPhone4). * Add support for printing! It's disabled by default. Use printEnabled in PSPDFViewController. (thanks to Cédric Luthi) * Add support for Open In...! It's disabled by default. Use openInEnabled in PSPDFViewController. * Improved, collapsable outline view. (Minor API changes for PSPDFOutlineParser) * Improved speed with using libjpeg-turbo. Enabled by default. * PSPDFStatusBarIgnore is now a flag, so the status bar style (which infers the navigation bar style) can now been set and then marked as ignore. * New property viewModeControlVisible, that shows/hides the toolbar view toggle. * Removes the UIView+Sizes category, that was not prefixed. * Remove custom PNG compression, performance wasn't good enough. * Internal GMGridView is now prefixed. * Disable implicit shadow animation when grid cell size changes. * Fixes a bug regarding slow rotation on the new iPad. * Fixes a bug where sometimes a pdf document wasn't unlocked correctly. * Fixes a potential problem where search/table of contents doesn't actually change the page on the iPhone. * Fixes some problems with Type2 Fonts on search. * Fixes a rare crash when rotating while a video is being displayed. ## 1.9.9 — 15 Mar 2012 * Icons! (changed outline icon, and replaced "Page" and "Grid" with icons) * Outline controller now has a title on the iPad. * Fixes a regression where the toolbar color was not correctly restored on the iPhone when modal controller were used. ## 1.9.8 — 14 Mar 2012 * Fixed a minor regression regarding scrobble bar updating. * Fixed issue where frame could be non-centered in pageCurl mode with some landscape documents when the app starts up in landscape mode. ## 1.9.7 — 14 Mar 2012 * PSPDFKit is now compiled with Xcode 4.3.1 and iOS SDK 5.1. Please upgrade. (It is still backwards compatible down to iOS 4.0.) * Allow adding the same file multiple times to PSPDFDocument. * Links are now blue and have a higher alpha factor. (old color was yellow and more obtrusive) * The animation duration of annotations is now customizable. See annotationAnimationDuration property in PSPDFViewController. * Link elements are not shown with exact metrics, and touches are tested for over-span area. Also, over-span area is now 15pixel per default. (old was 5) * Link elements now don't interfere with double/triple taps and only fire if those gestures failed. * Link elements no longer use an internal UIButton. (they are now handled by a global UITapGestureRecognizer) * Annotations are not size-limited to the actual document, no more "bleeding-out" of links. * Minimum size for embedded browser is now 200x200. (fixes missing Done button) * Inline browser can now also be displayed within a popover, using pspdfkit://[popover:YES,size:500x500]apple.com * Text highlighting is still disabled by default, but can be enabled with the new property createTextHighlightAnnotations in PSPDFAnnotationParser. * Fixes an issue where the navigation bar was restored too soon. Let me know if this change breaks behavior on your app. (The navigationBar is now restored in viewDidDisappear instead of viewWillDisappear, and also will be set in viewWillAppear) * Support tintColor property for inline browser. * Better support for invalid documents (that have no pages.) HUD can't be hidden while a document is invalid. UI buttons are disabled. * Fixes problem where link taps were not recognized on the site edges, advancing to the next/prev page instead in pageCurl mode. * Fixes issue where scrollOnTapPageEndEnabled setting was not honored in pageCurl mode. * Fixes a problem where the embedded mail sheet sometimes couldn't be closed. * Fixes a problem where touch coordinates on annotations where always in the frame center instead of the actual tap position. * Fixes a problem where adding items to the cache would sometimes spawn too much threads. * Fixes a potential crash in the inline browser. * Fixes a potential crash with accessing invalid memory on pageCurl deallocation. * Fixes a issue where certain URLs within pdf annotations were not correctly escaped. * Fixes a situation where the thumbnail grid could become invisible when rapidly switched while scrolling. * Fixes an issue where the HUD was hidden after a page rotate (which should not be the case) * Fixes weird animation with the navigationController toolbar when opening the inline browser modally. ## 1.9.6 — 6 Mar 2012 * New Inline Browser: PSPDFWebViewController. Annotations can be styled like pspdfkit://[modal:YES,size:500x500]apple.com or pspdfkit://[modal:YES]https://gmail.com. * New property in PSPDFViewController: linkAction. Decides the default action for PDF links (alert, safari, inline browser) * Add PSPDFStatusBarIgnore to completely disable any changes to the status bar. * Automatically close the Table of Contents controller when the user tapped on a cell. * Fixes sometimes missing data in the pageView didShowPage-delegate when using pageCurl mode. * Fixes (another) issue where status bar style was not restored after dismissing while in landscape orientation. * Fixes a severe memory leak with pageCurl mode. ## 1.9.5 — 5 Mar 2012 * Further tweaks on the scrobbleBar, improves handler in landscape mode. (thanks to @0xced) * Fixes a problem with pageCurl and the animation on the first page (thanks to Randy Becker) * Fixes an issue where double-tapping would zoom beyond maximum zoom scale. (thanks to Randy Becker) * Fixes issue where status bar style was not restored after dismissing while in landscape orientation. (thanks to Randy Becker) * Fixes some remote image display issues in the PSPDFKit Kiosk Example. * Fixes a regression with opening password protected pdf's. ## 1.9.4 — 4 Mar 2012 * Fixes a regression from 1.9.3 on single page documents. ## 1.9.3 — 1 Mar 2012 * Improves precision and stepping of the scrobbleBar. Now it's guaranteed that the first&last page are shown, and the matching between finger and page position is better. * Fixes a problem where sometimes page 1 should be displayed, but isn't in pageCurl mode. * Hide warnings for rotation overflow that UIPageViewController sometimes emits. ## 1.9.2 — 1 Mar 2012 * pageCurl can now be invoked from the edge of the device, even if the file is smaller. Previously, the gesture was not recognized when it wasn't started within the page view. * The incomplete support for text highlighting has been disabled. * removeCacheForDocument now has an additional parameter waitUntilDone. The previous behavior was NO, so just set NO if you use this and upgrade from an earlier release. * Fixes a potential cache-loop, where the device would constantly try to load new images. * Adds a safety check for loading images, and fixes a rare issue with images not showing up. ## 1.9.1 — 17 Feb 2012 * Allow scrolling to a specific rect and zooming: see scrollRectToVisible:(CGRect)rect animated:(BOOL)animated and (void)zoomToRect:(CGRect)rect animated:(BOOL)animated; * PSPDFAnnotationParser now allows setting custom annotations. (to complement or override pdf annotations) * New annotation type: Image. (jpg, png, tiff and all other formats supported by UIImage) * Better handling of situations with nil documents or documents where the actual file is missing. * Better alignment of the scrobble bar position image. * Add "mp4" as supported audio filetype. * Fixes ignored scrollingEnabled on PSPDFPageViewController. * Fixes event delegation in the Titanium module. * Fixes the method isFirstPage (checked for page = 1, but we start at page 0). * Renamed kPSPDFKitDebugLogLevel -> kPSPDFLogLevel. ## 1.9.0 — 13 Feb 2012 * PageCurl mode. Enable via setting "pageCurlEnabled" to YES. iOS5 only, falls back to scrolling on iOS4. * It's now possible to create a PSPDFDocument with initWithData! (thanks to @0xced) * Add support for pdf passwords! (Thanks to Steven Woolgar, Avatron Software) * Adds support for setting a custom tintColor on the toolbars. * Fixes a problem with PSPDFPageModeAutomatic and portrait/landscape page combinations. * Fixes various problems with __weak when the development target is set to iOS5 only. * Adds additional error checking when a context can't be created due to low memory. * Fixes flaky animations on the Simulator on the grid view. * Improves usage of PSPDFViewController within a SplitViewController (thanks to @0xced). * Removes a leftover NSLog. * Fixes a UID clashing problem with equal file names. Warning! Clear your cache, items will be re-generated in 1.9 (cache directories changed) * Fixes a bug with replacing local directory path with Documents/Cache/Bundle. (thanks to Peter) * Fixes a retain cycle in PSPDFAnnotationParser (thanks to @0xced). * Fixes a retain cycle on UINavigationController (thanks to Chan Kruse). * Fixes a problem where the scrobble bar tracking images were sometimes not updated. * Fixes a rare race condition where rendering could get stuck. * Improves handling of improper PSPDFDocument's that don't have a uid set. * Allow adding of UIButtons to gridview cells. * Added "Cancel" and "Open" to the localization bundle. (mailto: links) * Setting the files array is now possible in PSPDFDocument. * The cache now uses MD5 to avoid conflicts with files of the same name. (or multiple concatenated files) * Better handling of rendering errors (error objects are returned) * Search controller is now auto-dismissed when tapped on a search result. * PSPDFPositionView more closely resembles iBooks. (thanks to Chan) * PDF cache generation is no no longer stopped in the viewWillDisappear event (only on dealloc, or when document is changed) * Titanium: Add ability to hide the close button. Note: For pageCurl, Apple's UIPageViewController is used. This class is pretty new and still buggy. I had to apply some private API fixes to make it work. Those calls are obfuscated and AppStore-safe. If you have any reasons to absolutely don't use those workarounds, you can add _PSPDFKIT\_DONT\_USE\_OBFUSCATED\_PRIVATE\_API_ in the preprocessor defines. (only in the source code variant) This will also disable the pageCurl feature as the controller will crash pretty fast when my patches are not applied. Don't worry about this, I have several apps in the store that use such workarounds where needed, it never was a problem. Also, I reported those bugs to Apple and will keep track of the fixes, and remove my workarounds for newer iOS versions if they fix the problem. ## 1.8.4 — 27 Dec 2011 * Fixes a problem where search highlights were not displayed. * Updated git version scripts to better work with branches. (git rev-list instead of git log) ## 1.8.3 — 26 Dec 2011 * Update internally used TTTAttributedString to PSPDFAttributedString; prevent naming conflicts. * Fallback to pdf filename if pdf title is set but empty. * pageMode can now be set while willAnimateRotationToInterfaceOrientation to customize single/double side switching. * Fixes a problem with the document disappearing in certain low memory situations. ## 1.8.2 — 25 Dec 2011 * Uses better image pre-caching code; now optimizes for RGB screen alignment; smoother scrolling! * Fixes a regression with scrobble bar hiding after animation. * Fixes wrong toolbar offset calculation on iPad in landscape mode. * Various performance optimizations regarding CGPDFDocument, HUD updates, thumbnails, cache creation. * Lazy loading of thumbnails. ## 1.8.1 — 23 Dec 2011 * UINavigationBar style is now restored when PSPDFViewController is popped back. * Annotation page cache is reset when protocol is changed. * Fixes Xcode Archive problem because of public header files in PSPDFKit-lib.xcodeproj * Fixes a regression with the Web-AlertView-action not working. ## 1.8.0 — 21 Dec 2011 * Search Highlighting! This feature is still in BETA, but already works with many documents. If it doesn't work for you, you can disable it with changing the searchMode-property in PSPDFDocumentSearcher. We're working hard to improve this, it just will take some more time until it works on every document. As a bonus, search is now fully async and no longer blocks the main thread. * ARC! PSPDFKit now internally uses ARC, which gives a nice performance boost and makes the codebase a lot cleaner. PSPDFKit is still fully compatible with iOS4 upwards. You need to manually include libarclite.so if you are not using ARC and need compatibility with iOS4. Check the MinimalExample.xcodeproj to see how it's done. (You can drag the two libarclite-libraries directly in your project). If you use the PSPDFKit-lib.xcodeproj as a submodule, you don't have to think about this, Xcode is clever enough to not expose this bug here. See more about this at https://www.nutrient.io/guides/. * New default shadow for pages. More square, iBooks-like. The previous shadow is available when changing shadowStyle in PSPDFScrollView. The shadow override function has been renamed to pathShadowForView. * New: PSPDFDocument now uses the title set in the pdf as default. Use setTitle to set your own title. Title is now also thread-safe. * New Thumbnail-Framework (removed AQGridView). Faster, better animations, allows more options. Thumbnails are now centered. You can override this behavior with subclassing gridView in PSPDFViewController. * New: HUD-elements are now within hudView, hudView is now a PSPDFHUDView, lazily created. * New: Page position is now displayed like in iBooks at the bottom page (title is now just title) * Changed: Videos don't auto play per default. Change the url to pspdfkit[autoplay:true]://devimages.apple.com/iphone/samples/bipbop/bipbopall.m3u8 to restore the old behavior (or use delegates). * Changed: viewMode does not longer animate per default. Use the new setViewMode:animated: to change it with animation. * Changed: the left section of the toolbar now uses iOS5-style leftToolBarButtons if available; falls back to custom UIToolBar in iOS4. * Shortly pressed link targets are now highlighted with a minimum duration. * Alert is no longer displayed for URLs that can't be opened by the system. * Support detection of "m4v" as video annotation. * Improves performance when caching very large documents. * Expose the borderColor of PSPDFLinkAnnotationView; set in one of the delegates. * Removes a lot of glue code and switches to KVO for many view-related classes (Scrobble Bar) * Add methods to check if PSPDFPageInfo is already available, improves thumbnail speed. * Add generic support to override classes. See the property "overrideClassNames" for details. This replaces "scrollViewClass" and "scrobbleBarClass" and is much more flexible. Just use a key/value pair of NSStrings with default/new class names and your custom subclass will be loaded. * setScrobbleBarEnabled is now animatable. * The protocolString for the multimedia link annotation additions can now be set in PSPDFAnnotationParser (defaults to pspdfkit://). * didTapOnPage is now didTapOnPageView, the former is deprecated. * PSPDFPageCoordinates now show a nice description when printed. * Many deprecated delegate calls have been removed. Check your calls. * Version number is now directly written from the git repository. (PSPDFVersionString() is now more accurate) * When a link annotation is tapped, the HUD no longer shows/hides itself. * HUD show/hide is now instant, as soon as scrolling is started. No more delays. * Scrollbar is now only changed if controller is displayed in full-screen (non-embedded). * Fixes a issue where PSPDFKit would never release an object if annotations were disabled. * Fixes a bug where the outline was calculated too often. * Fixes an issue where the title was re-set when changing the file of a pdf. * Fixes problems with syntax highlighting of some files. Xcode 4.3 works even better; use the beta if you can. * Fixes a bug with video player when auto play is not enabled. * Fixes encoding for mailto: URL handler (%20 spaces and other encoded characters are now properly decoded) * Fixes potential crash with recursive calls to scrollViewDidScroll. * Fixes a rare crash when delegates are changed while being enumerated. * Lots of other small improvements. ## 1.7.5 — 1 Dec 2011 * Fixes calling the deprecated delegate didShowPage when didShowPageView is not implemented. (thanks Albin) ## 1.7.4 — 29 Nov 2011 * Custom lookup for parent viewcontroller - allows more setups of embedded views. * Fixes a crash related to parsing table of contents. ## 1.7.3 — 29 Nov 2011 * Add a log warning that the movie/audio example can crash in the Simulator. Known Apple bug. Doesn't happen on the device. * PSPDFCache can now be subclassed. Use kPSPDFCacheClassName to set the name of your custom subclass. * Fixes a bug where scrollingEnabled was re-enabled after a zoom operation. ## 1.7.2 — 29 Nov 2011 * Changes delegates to return PSPDFView instead of the page: didShowPageView, didRenderPageView. * Improve zoom sharpness. (kPSPDFKitZoomLevels is now set to 5 per default from 4; set back if you experience any memory problems on really big documents.) * Increase tiling size on iPad1/older devices to render faster. * Reduce loading of unneeded pages. Previously happened sometimes after fast scrolling. This also helps when working with delegates. * Fixes a locking race condition when using PSPDFDocument.twoStepRenderingEnabled. ## 1.7.1 — 29 Nov 2011 * Fixes a rare crash when encountering non-standardized elements while parsing the Table of Contents. ## 1.7.0 — 28 Nov 2011 * PSPDFKit now needs at least Xcode 4.2/Clang 3.0 to compile. * Following new frameworks are required: libz.dylib, ImageIO.framework, CoreMedia.framework, MediaPlayer.framework, AVFoundation.framework. * Images are now compressed with JPG. (which is usually faster) If you upgrade, add an initial call to [[PSPDFCache sharedPSPDFCache] clearCache] to remove the png cache. You can control this new behavior or switch back to PNGs with PSPDFCache's useJPGFormat property. * Optionally, when using PNG as cache format, crushing can be enabled, which is slower at writing, but faster at reading later on. (usually a good idea!) * New multimedia features! Video can now be easily embedded with a custom pspdfkit:// url in link annotations. Those can be created with Mac Preview.app or Adobe Acrobat. Try for example "pspdfkit://devimages.apple.com/iphone/samples/bipbop/bipbopall.m3u8" to get the HTTP Live streaming test video. * Link annotations are now UIButtons. This allows more interactivity (feedback on touch down), and also changes the default implementation of PSPDFDocument's drawAnnotations function to be empty. Clear the cache after updating, or else you get two borders. You can also return to the old behavior if you return NO on shouldDisplayAnnotation (PSPDFViewControllerDelegate) anytime an annotation of type PSPDFAnnotationTypeLink is sent. * Localization is now handled via the PSPDFKit.bundle. You can either change this, or use PSPDFSetLocalizationDictionary to add custom localization. * PSPDFLinkAnnotation is renamed to PSPDFAnnotation and adds a new helper function to get the annotation rect. * PSPDFPage is refactored to PSPDFPageView and is now the per-page container for a document page. The delegate methods have been changed to return the corresponding PSPDFPageView. Within PSPDFPageView, you can get the parent scrollview PSPDFScrollView. * PSPDFPageModeAutomatic is now more intelligent and only uses dual page mode if it actually improves reading (e.g. no more dual pages on a landscape-oriented document) * PSPDFKitExample: fixes delete-image positioning in long scroll lists. * new: use PSPDFPageInfo everywhere to allow custom rotation override. (- (PSPDFPageInfo *)pageInfoForPage:(NSUInteger)page pageRef:(CGPDFPageRef)pageRef) * new delegate options to allow dynamic annotation creation. * Better size calculation for the toolbar, allows changing titles to longer/shorter words and resizing automatically. * PSPDFDocument now uses the title of the pdf document (if available). You can override this with manually setting a title. * New option "scrollingEnabled" to be able to lock scrolling. (e.g. when remote controlling the pdf) * Improves speed on image pre-caching. * Improves documentation. * Fixes a rotation problem with the last magazine page. * Fixes a bug where scrollPage w/o animation didn't show the page until the user scrolled. * Fixes a potential crash when view was deallocated while popover was opened. * Fixes a deadlock with clearCache. ## 1.6.20 — 18 Nov 2011 * fixes possible cache-reload loop with page-preload if non-odd values are chosen. * fixes a memory leak (regression in 1.6.18) ## 1.6.19 — 16 Nov 2011 * further small rotation improvement. ## 1.6.18 — 16 Nov 2011 * New: Much, much improved rotation. Now smooth as butter. Enjoy! ## 1.6.17 — 12 Nov 2011 * In search results, "Site" was renamed to "Page" to be consistent with the toolbar. If you use custom localization, you have to rename the entry "Site %d" to "Page %d". * add API call to allow basic text extraction from the search module (magazine.documentSearcher) ## 1.6.16 — 12 Nov 2011 * fixes a bug with invalid caching entries when a deleted document is re-downloaded in the same application session (pages suddenly went black) * add a custom lib-project for PSPDFKit; it's now easier than ever to integrate it. Note: you really should use that one - I'll switch over to ARC soon, so a library makes things easier. ## 1.6.15 — 5 Nov 2011 * thumbnails are now displayed under the transparent bar, not overlapping * only enable outline if it's enabled and there actually is an outline (no more empty popovers) * mail links are now presented in a form sheet on the iPad * allow show/hide of navigation bar even when zoomed in ## 1.6.14 — 22 Oct 2011 * fixes bug where delete method of PSPDFCache (removeCacheForDocument) was deleting the whole directory of the pdf instead of just the related files ## 1.6.13 — 22 Oct 2011 * removed the zeroing weak reference helper. If you use custom delegates for PSPDFCache, you now need to manually deregister them. Upside: better management of delegates. ## 1.6.12 — 19 Oct 2011 * changed: turns out, when compiling with Xcode 4.2/Clang, you'll loose binary compatibility with objects linked from 4.1. Thus, the framework crashed with EXC_ILLEGAL_INSTRUCTION when compiled within an older Xcode. I will use 4.1 some more time to give everyone the change to upgrade, but due to some *great* improvements in Clang 3.0 compiler that ships with Xcode 4.2 (e.g. nilling out of structs accessed from a nil object) it's highly advised that you use Xcode 4.2. If you use the source code directly, this is not an issue at all. ## 1.6.11 — 14 Oct 2011 * new: PSPDFKit is now compiled with Xcode 4.2/iOS Base SDK 5.0 (still works with 4.x) * improves compatibility for outline parser; now able to handle rare array/dict destination variants (fixes all destinations = page 1 error) * fixes a rare stack overflow when re-using zoomed scrollviews while scrolling. * fixes a compile problem on older Xcode versions. (It's not officially supported though - use Xcode 4.2 for the best experience!) * fixes a memory problem where iPad1 rarely tries to repaint a page forever ## 1.6.10 — 25 Sep 2011 * aspectRatioEqual now defaults to NO. Many customers oversee this and then send me (false) bug reports. Set this to YES for maximum speed if your document has one single aspect ratio (like most magazines should). * scroll to active page in grid view * fixes small offset-error in the scrobble bar ## 1.6.9 — 22 Sep 2011 * add option do debug memory usage (Instruments isn't always great) * improves memory efficiency on tile drawing, animations * improves performance, lazily creates gridView when first accessed * improves scrobble bar update performance * fixes memory problems on older devices like iPad 1, iPhone 3GS * fixes a problem with unicode files * fixes auto-switch to fitWidth on iPhone when location is default view ## 1.6.8 — 15 Sep 2011 * update thumbnail grid when document is changed via property ## 1.6.7 — 15 Sep 2011 * improves outline parser, now handles even more pdf variants ## 1.6.6 — 15 Sep 2011 * potential bug fix for concurrent disk operations (NSFileManager is not thread safe!) * fixes positioning problem using the (unsupported) combination of PSPDFScrollingVertical and fitWidth ## 1.6.5 — 15 Sep 2011 * fixes a bug where scroll position was remembered between pages when using fitWidth ## 1.6.4 — 15 Sep 2011 * new: didRenderPage-delegate * fixes: crash bug with NaN when started in landscape ## 1.6.3 — 14 Sep 2011 * new: maximumZoomScale-property is exposed in PSPDFViewController * changed: *realPage* is now remembered, not the page used in the UIScrollView. This fixes some problems with wrong page numbers. * fixes situation where page was changed to wrong value after view disappeared, rotated, and reappeared. * fixes option button in example is now touchable again * fixes a bug where HUD was never displayed again when rotating while a popover controller was visible * fixes potential crash where frame get calculated to NaN, leading to a crash on view rotation * fixes problems when compiling with GCC. You really should use LLVM/Clang though. ## 1.6.2 — 13 Sep 2011 * fixed: HUD is now black again on disabled status bar ## 1.6.1 — 13 Sep 2011 * new: open email sheet per default when detecting mailto: annotation links. (You now need the MessageUI.framework!) * new: fileUrl property in PSPDFDocument * improve toolbar behavior when setting status bar to default * fixes memory related crash on older devices * fixes crash when toolbarBackButton is nil * greatly improved KioskExample ## 1.6.0 — 12 Sep 2011 * changed: willShowPage is now deprecated, use didShowPage. Both now change page when page is 51% visible. Former behavior was leftIndex * changed: pageCount is now only calculated once. If it's 0, you need to call clearCacheForced:YES to reset internal state of PSPDFDocument * changed: iPhone no longer uses dualPage display in landscape, now zooms current page to fullWidth * new: property fitWidth in PSPDFViewController lets you enable document fitting to width instead of largest element (usually height). Only works with horizontal scrolling * new: thumbnails in Grid, ScrobbleBar, KioskExample are now faded in * new: pdf view fades in. Duration is changeable in global var kPSPDFKitPDFAnimationDuration. * new: new property preloadedPagesPerSide in PSPDFViewController, controls pre-caching of pages * new: add delegates for page creation (willLoadPage/didLoadPage/willUnloadPage/didUnloadPage) with access to PSPDFScrollView * new: pdf cache handle is cleared on view controller destruction * new: exposes pagingScrollView in PSPDFViewController * new: HUD transparency is now a setting (see PSPDFKitGlobal) * new: scrobble bar class can be overridden and set in PSPDFViewController * new: directionalLock is enabled for PSPDFScrollView.
