在主uiview上的子视图上获取click事件

Question

我有一个滚动图像+分页的视图.我在UIVIEW上添加了这些图像,并将此UIView添加到主视图中.我想在scrollview中检测图像上的click事件,并在主视图中处理它们.

我该怎么做？

请帮忙

Answer 1

您可以使用手势识别器解决问题.

// 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,在点击图像视图时会调用此方法

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

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