UITableView添加UITapGestureRecognizer与didSelectRowAtIndexPath冲突解决

//添加手势，点击屏幕其他区域关闭键盘的操作  

     UITapGestureRecognizer *gesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(hidenKeyboard)];  

   gesture.numberOfTapsRequired = 1;    //2就是双击 

   [self.view addGestureRecognizer:gesture]; 

 

在UITableView上添加了UITapGestureRecognizer后会导致didSelectRowAtIndexPath失效，原因是UITapGestureRecognizer会截取了tableView的touch事件，导致无法响应行选择，解决方法是重写UIGestureRecognizerDelegate中的

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

{

    if ([NSStringFromClass([touch.view class]) isEqualToString:@"UITableViewCellContentView"]) {//如果当前是tableView

        //做自己想做的事

        return NO;

    }

    return YES;   

}

 

 

首先将本类继承 UIGestureRecognizerDelegate

然后在开始的代码中添加

gesture.delegate=self;
