# Selecting text in our iOS viewer

Text selection is controlled via [`TextSelectionView`](https://www.nutrient.io/api/ios/documentation/pspdfkitui/textselectionview), which is part of every [`PDFPageView`](https://www.nutrient.io/api/ios/documentation/pspdfkitui/pdfpageview), and it can be accessed using the [`selectionView`](https://www.nutrient.io/api/ios/documentation/pspdfkitui/pdfpageview/selectionview) property.

[`PDFViewControllerDelegate`](https://www.nutrient.io/api/ios/documentation/pspdfkitui/pdfviewcontrollerdelegate) has delegate methods that allow you to selectively block text selection ([`pdfViewController(_:shouldSelectText:with:at:on:)`](https://www.nutrient.io/api/ios/documentation/pspdfkitui/pdfviewcontrollerdelegate/pdfviewcontroller(_:shouldselecttext:with:at:on:))) and to be notified whenever a text has been selected ([`pdfViewController(_:didSelectText:with:at:on:)`](https://www.nutrient.io/api/ios/documentation/pspdfkitui/pdfviewcontrollerdelegate/pdfviewcontroller(_:didselecttext:with:at:on:))).

Another flexible option is the [`allTextInteractions`](https://www.nutrient.io/api/ios/documentation/pspdfkitui/documentviewinteractions/alltextinteractions) [interaction component](https://www.nutrient.io/guides/ios/customizing-the-interface/handling-user-interactions.md).

Text selection can also be disabled via the [`isTextSelectionEnabled`](https://www.nutrient.io/api/ios/documentation/pspdfkitui/pdfconfiguration/istextselectionenabled) switch in the configuration object.

Text can be programmatically selected via setting [`selectedGlyphs`](https://www.nutrient.io/api/ios/documentation/pspdfkitui/textselectionview/selectedglyphs) or [`selectedImage`](https://www.nutrient.io/api/ios/documentation/pspdfkitui/textselectionview/selectedimage) for image selection. Set these properties to `nil` to clear the current selection.
