A Boolean value determining whether the receiver delays sending touches in a begin phase to its view.
- iOS 3.2+
- Mac Catalyst 13.0+
- tvOS 9.0+
When the value of this property is
false (the default), views analyze touch events in
UITouch in parallel with the receiver. When the value of the property is
true, the window suspends delivery of touch objects in the
UITouch phase to the view. If the gesture recognizer subsequently recognizes its gesture, these touch objects are discarded. If the gesture recognizer, however, does not recognize its gesture, the window delivers these objects to the view in a
touches message (and possibly a follow-up
touches message to inform it of the touches’ current locations). Set this property to
true to prevent views from processing any touches in the
UITouch phase that may be recognized as part of this gesture.
