Pan Gestures in Swift

Save

A pan gesture occurs when the user moves one or more fingers around the device screen. UIPanGestureRecognizer is a concrete subclass of UIGestureRecognizer. It use the UIPanGestureRecognizer class for pan gestures and the UIScreenEdgePanGestureRecognizer class for screen-edge pan gesture.

The user must press one or more fingers on a view while panning on the screen. A panning gesture is on continuous action when the user moves one or more fingers allowed (minimumNumberOfTouches) to enough distance for recognition as a pan. It changes when the user moves a finger while pressing with the minimum number of fingers. At last, it ends (UIGestureRecognizer.State.ended) when the user lifts all fingers.
