Questions tagged [uipinchgesturerecognizer]

UIPinchGestureRecognizer is a concrete subclass of UIGestureRecognizer that looks for pinching gestures involving two touches.

When the user moves the two fingers toward each other, the conventional meaning is zoom-out; when the user moves the two fingers away from each other, the conventional meaning is zoom-in.

Pinching is a continuous gesture. The gesture begins (UIGestureRecognizerStateBegan) when the two touches have moved enough to be considered a pinch gesture. The gesture changes (UIGestureRecognizerStateChanged) when a finger moves (with both fingers remaining pressed). The gesture ends (UIGestureRecognizerStateEnded) when both fingers lift from the view.
