UILongPressGestureRecognizer

UILongPressGestureRecognizer is a concrete subclass of UIGestureRecognizer that looks for long-press gestures. The user must press one or more fingers on a view and hold them there for a minimum period of time before the action triggers. While down, the user’s fingers may not move more than a specified distance; if they move beyond the specified distance, the gesture fails.

Overview

Long-press gestures are continuous. The gesture begins (began) when the number of allowable fingers (numberOfTouchesRequired) have been pressed for the specified period (minimumPressDuration) and the touches do not move beyond the allowable range of movement (allowableMovement). The gesture recognizer transitions to the Change state whenever a finger moves, and it ends (ended) when any of the fingers are lifted.
