I am using the following handler for a IUPanGesture. However when the pan ends, the UIView that it is moving disappears. Do I need to add anything else to this code? - (void)pan:(UIPanGestureRecognizer *)gesture { if ((gesture.state == UIGestureRecognizerStateChanged) || (gesture.state == UIGestureRecognizerStateEnded)) { CGPoint location = [gesture locationInView:[self superview]]; [self setCenter:location]; } }
