推荐答案

将手势识别器添加到必要的图像视图中:

Add gesture recognizer to the necessary image view:

UITapGestureRecognizer *frameTapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(frameTapGesture:)];
[_imgView addGestureRecognizer:frameTapGesture];

然后在手势处理程序中访问附加到的视图手势识别器:

Then in the gesture handler get access to the view gesture recognizer attached to:

- (void)frameTapGesture:(UITapGestureRecognizer*)sender
{
    UIView *view = sender.view; //cast pointer to the derived class if needed
    NSLog(@"%d", view.tag);
}
