Exclude subviews from UIGestureRecognizer

I used the simple way below. It works perpectly!

Implement UIGestureRecognizerDelegate function, accept only touchs on superview, not accept touchs on subviews:

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch
{
    if (touch.view != _mySuperView) { // accept only touchs on superview, not accept touchs on subviews
        return NO;
    }

    return YES;
}
