In this chapter, we know this method
- (void)moveLine:(UIPanGestureRecognizer *)gr[/code]
of UIPanGestureRecognizer is called when user clicks some area
and while holding down the finger, moves it to somewhere else.
My question is, during this time, why is not the
- (void)touchesMoved:(NSSet *)touches
method of UIResponder get called simultaneously???
