A set of methods for fine-tuning a gesture recognizer’s behavior.
Use the methods in this protocol to establish dynamic dependencies between gesture recognizers and to prevent a single gesture recognizer from acting at all.
Regulating Gesture Recognition
Controlling Simultaneous Gesture Recognition
Setting Up Failure Requirements
Called, for a new touch, before the system calls the
touchesBegan:withEvent: method on the gesture recognizer. Return
NO to prevent the gesture recognizer from seeing this touch.
An object that monitors events and calls its action method when a predefined sequence of events occur.
