使用UIGestureRecognizerDelegate，识别单击事件

首先.h文件添加

UIGestureRecognizerDelegate

 

    //长按设置情景模式
    UILongPressGestureRecognizer *longPress = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longPressShowView:)];
    [self.view addGestureRecognizer:longPress];
    [longPress release];
    
    UITapGestureRecognizer* singleRecognizer  = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(removePtzGuide)];
    singleRecognizer.numberOfTapsRequired = 1; // 单击
    singleRecognizer.delegate = self;
    [self.view addGestureRecognizer:singleRecognizer];
    [singleRecognizer release];

这里一个是长按，另外则是单击

需要实现UIGestureRecognizerDelegate代理函数

#pragma mark - UIGestureDelegate
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch
{
    if ([touch.view isKindOfClass:[QuadCurveMenuItem class]])
    {
        return NO;
    }
    if ([touch.view isKindOfClass:[KxMenuOverlay class]])
    {
        [[NSNotificationCenter defaultCenter] postNotificationName:@"dismissMenu" object:nil];
    }
    if ([touch.view isKindOfClass:[UISlider class]]) {
        return NO;
    }
    else
    {
        return YES;
    }
}

return yes则响应这个事件，反之则无响应，这样可以过滤掉一些不需要响应或者重复的事件
