Find the leaks (AKA as - the reason I shot myself in the head)

is it that you redefined currentPointY in the first if, using a new currentPointY instead of the one in the function scope? Or that you didn't use static on the first currentPointY so when reentering the function currentPointY when sender.state == UIGestureRecognizerStateChanged is undefined?
