# touchesShouldBegin(_:with:in:) Overridden by subclasses to customize the default behavior when a finger touches down in displayed content. ``` func touchesShouldBegin(_ touches: Set, with event: UIEvent?, in view: UIView) -> Bool ``` ## Parameters `touches` A set of [`UITouch`](/documentation/UIKit/UITouch) instances that represent the touches for the starting phase of the event represented by `event`. `event` An object representing the event to which the touch objects in `touches` belong. `view` The subview in the content where the touch-down gesture occurred. ## Return Value Return if you don’t want the scroll view to send event messages to `view`. If you want `view` to receive those messages, return (the default). ## Discussion The default behavior of [`UIScrollView`](/documentation/UIKit/UIScrollView) is to invoke the [`UIResponder`](/documentation/UIKit/UIResponder) event-handling methods of the target subview that the touches occur in. --- Copyright © 2026 Apple Inc.
