我有一个手势识别器设置,以便在点击屏幕时我的工具栏向下滑动.当我点击栏上的按钮时,这就算是一个点击.在这些情况下如何取消手势？

谢谢

您可以查看SimpleGestureRecognizers示例项目.

- (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;
}
