IOS UIView直接响应点击事件的解决方法

UIView的手势处理能够响应点击事件。(此处使用 UIImageView 做为示例)

  1.  self.allScreenImg.userInteractionEnabled = YES;／／UIImageView默认不响应手势，须要开启userInteractionEnabled

    ／／处理单击事件

    UITapGestureRecognizer* singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(clickAllScreen:)];

    [self.allScreenImg addGestureRecognizer:singleTap];

2. 添加处理的方法

- (void) clickAllScreen:(UITapGestureRecognizer *) recognizer {

    AllScreenViewController* recordViewController = [[AllScreenViewController alloc] initWithStoryboard];

    [self.navigationController pushViewController:recordViewController animated:YES];

}

以上操做便可以响应了UIImageView的点击事件了。

方法二：

为UIImageView设置tag，直接处理手势 以处理单击事件：

    p_w_picpathView.setTag = 333;

   －（void）touchesBegan:(NSSet *) touches withEvent:(UIEvent *) event {

        UIImageView* img = (UIImageView *) [self.view viewWithTag: 333];

        if (img) {

            // TODO some thing

        }

    }
