A Boolean value affecting whether touches are delivered to a view when a gesture is recognized.
- iOS 3.2+
- tvOS 9.0+
When this property is
true (the default) and the receiver recognizes its gesture, the touches of that gesture that are pending are not delivered to the view and previously delivered touches are cancelled through a
touches message sent to the view. If a gesture recognizer doesn’t recognize its gesture or if the value of this property is
false, the view receives all touches in the multi-touch sequence.
