Discussion
The default implementation of this method does nothing. Use this method to update the state of your gesture recognizer in whatever way is appropriate.
A gesture recognizer monitors events that occur in its view (and any subviews) but does not take part in the responder chain itself. The gesture recognizer receives events before any views do. Use the delaysKeyEvents property to control whether event is propagated to the view.
