iOS 为UIView设置点击监听事件

// In the view controller where you create the subviews// (not sure from your question, but I think you are adding image views to a scroll viewUIView *view = [[UIView alloc] init];UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(viewTapped:)];[view addGestureRecognizer:tap];

- (void)imageViewTapped:(UITapGestureRecognizer *)gr {    UIImageView *theImageViewThatGotTapped = (UIImageView *)gr.view;}
