The event to which the touches belong.
UIKit calls this method when a finger or Apple Pencil is no longer touching the screen. Many UIKit classes override this method and use it to clean up state involved in the handling of the corresponding touch events. The default implementation of this method forwards the message up the responder chain. When creating your own subclasses, call
super to forward any events that you do not handle yourself. For example,
If you override this method without calling super (a common use pattern), you must also override the other methods for handling touch events, even if your implementations do nothing.
