Overview
UILongPressGestureRecognizer is a concrete subclass of UIGestureRecognizer that looks for long-press gestures. The user must press one or more fingers on a view for at least a specified period for the action message to be sent. In addition, the fingers may move only a specified distance for the gesture to be recognized; if they move beyond this limit the gesture fails.
