点击按钮时忽略 UIGestureRecognizer

我设置了一个手势识别器，以便在点击屏幕时我的工具栏会向下滑动。当我点击栏上的按钮时，即算作一次点击。在这些情况下如何取消手势？

Thanks

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch {

    // Disallow recognition of tap gestures in the button.
    if ((touch.view == button) && (gestureRecognizer == tapRecognizer)) {
        return NO;
    }
    return YES;
}
