# UIScribbleInteractionDelegate Methods for customizing or suppressing Scribble behavior within text input views. ``` @MainActor protocol UIScribbleInteractionDelegate : NSObjectProtocol ``` ## Overview By default, Scribble let users enter text by writing directly into any editable view that implement [`UITextInput`](/documentation/UIKit/UITextInput). In apps with customized text fields, you can use the [`UIScribbleInteractionDelegate`](/documentation/UIKit/UIScribbleInteractionDelegate) callbacks to optimize the UI for a better writing experience, including: - Opting individual text fields in or out of Scribble interactions. - Controlling how quickly a given text field responds to input, giving the view an opportunity to change its configuration, if necessary. - Receiving notifications when the user writing begins and ends. ## Topics ### Allowing and controlling Scribble interactions [`scribbleInteraction(_:shouldBeginAt:)`](/documentation/UIKit/UIScribbleInteractionDelegate/scribbleInteraction(_:shouldBeginAt:)) Returns a Boolean value that indicates whether the delegate should allow writing at a specific location in the view. [`scribbleInteractionShouldDelayFocus(_:)`](/documentation/UIKit/UIScribbleInteractionDelegate/scribbleInteractionShouldDelayFocus(_:)) Tells the delegate to delay focusing the text input view. ### Tracking Scribble input [`scribbleInteractionWillBeginWriting(_:)`](/documentation/UIKit/UIScribbleInteractionDelegate/scribbleInteractionWillBeginWriting(_:)) Informs the delegate when the user begins writing in the view. [`scribbleInteractionDidFinishWriting(_:)`](/documentation/UIKit/UIScribbleInteractionDelegate/scribbleInteractionDidFinishWriting(_:)) Informs the delegate that the user stops writing in the view, after Scribble transcribes and enters the last word. --- Copyright © 2026 Apple Inc.
