Discussion

The runtime calls this method after the gesture-recognizer state has been set to UIGestureRecognizer.State.ended, recognized, UIGestureRecognizer.State.cancelled, or UIGestureRecognizer.State.failed—in other words, any of the terminal states for a gesture recognition attempt. Subclasses should reset any internal state in preparation for a new attempt at gesture recognition. After this method is called, the gesture recognizer receives no further updates for touches that have begun but haven’t ended.
