# touchesCancelled(_:with:) Sent to the gesture recognizer when a system event (such as an incoming phone call) cancels a touch event. ``` func touchesCancelled(_ touches: Set, with event: UIEvent) ``` ## Parameters `touches` A set of [`UITouch`](/documentation/UIKit/UITouch) instances in the event represented by `event` that represent the touches in the [`UITouch.Phase.cancelled`](/documentation/UIKit/UITouch/Phase-swift.enum/cancelled) phase. `event` A [`UIEvent`](/documentation/UIKit/UIEvent) object representing the event to which the touches belong. ## Discussion This method has the same exact signature as the corresponding one declared by [`UIResponder`](/documentation/UIKit/UIResponder). Through this method a gesture recognizer receives touch objects (in their [`UITouch.Phase.cancelled`](/documentation/UIKit/UITouch/Phase-swift.enum/cancelled) phase) before the view attached to the gesture recognizer receives them. `UIGestureRecognizer` objects are not in the responder chain, yet observe touches hit-tested to their view and their view’s subviews. After observation, the delivery of touch objects to the attached view, or their disposition otherwise, is affected by the [`cancelsTouchesInView`](/documentation/UIKit/UIGestureRecognizer/cancelsTouchesInView), [`delaysTouchesBegan`](/documentation/UIKit/UIGestureRecognizer/delaysTouchesBegan), and [`delaysTouchesEnded`](/documentation/UIKit/UIGestureRecognizer/delaysTouchesEnded) properties. Upon receiving this message, the gesture recognizer for a continuous gesture should set its state to [`UIGestureRecognizer.State.cancelled`](/documentation/UIKit/UIGestureRecognizer/State-swift.enum/cancelled); a gesture recognizer for a discrete gesture should set its state to [`UIGestureRecognizer.State.failed`](/documentation/UIKit/UIGestureRecognizer/State-swift.enum/failed). --- Copyright © 2026 Apple Inc.
