详细内容

UIScrollView \ UITableViewCell 添加 UIButton 时不响应滑动操作问题

//1.添加单击事件
...
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(60, 0, listV.frame.size.width - 60, listV.frame.size.height)];  
label.userInteractionEnabled=YES;  
label.tag = 100;
UITapGestureRecognizer *labelTapGestureRecognizer = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(labelTouchUpInside:)];  
[label addGestureRecognizer:labelTapGestureRecognizer];  
...

//2.获取单击事件
-(void) labelTouchUpInside:(UITapGestureRecognizer *)recognizer
{  
   UILabel *label=(UILabel*)recognizer.view;  
   NSLog(@"%@ -- Tag : %ld",label.text,label.tag);  
}

UIScrollView 中添加 UITapGestureRecognizer 跟 UIButton 点击事件冲突

//1.添加单击事件
...
UITapGestureRecognizer *gensture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(scrollViewTapAction)];
gensture.delegate = self;
[scrollView addGestureRecognizer:gensture];
...

//2.实现 UIGestureRecognizerDelegate 中的代理方法

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch
{ 
    UIView *view = [touch view]; 
    if ([view isKindOfClass:[UIButton class]]) 
    { 
        return NO; 
    } 

    return YES;
}
