iphone - 在主uiview的 subview 上获取点击事件

Question

我有一个包含滚动图像 + 分页的 View 。我已将这些图像添加到 UIVIEW 上，并将此 UIView 添加到主视图。我想在 ScrollView 中检测图像上的点击事件并在主视图中处理它们。

我该怎么做？

请帮忙

你可以用手势识别器解决这个问题。

// 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 view

UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake...];
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(imageViewTapped:)];
[imageView addGestureRecognizer:tap];

现在，这将在 ImageView 被点击时被调用

- (void)imageViewTapped:(UITapGestureRecognizer *)gr {

    UIImageView *theImageViewThatGotTapped = (UIImageView *)gr.view;
}
