IOS UIView直接響應點擊事件的解決方法

UIView的手勢處理能夠響應點擊事件。(此處使用 UIImageView 做爲示例)

  1.  self.allScreenImg.userInteractionEnabled = YES;／／UIImageView默認不響應手勢，須要開啓userInteractionEnabled

    ／／處理單擊事件

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

    [self.allScreenImg addGestureRecognizer:singleTap];

2. 添加處理的方法

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

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

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

}

以上操做便可以響應了UIImageView的點擊事件了。

方法二：

爲UIImageView設置tag，直接處理手勢 以處理單擊事件：

    p_w_picpathView.setTag = 333;

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

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

        if (img) {

            // TODO some thing

        }

    }
