从imageview点击手势获取索引或标记值 [英] get index or tag value from imageview tap gesture

问题描述

这是每当我们搜索任何应用时，来自应用商店的图片。我还想添加相同的scrollview概念，在该概念中，它显示了上一个和下一个图像的小预览的currentimage。我可以在示例代码。但是没有找到任何解决方案，当用户点击任何图像时如何获得索引或标记值。这样我就可以打开每个图像的详细信息页面。如果有人对此有所了解，请帮帮我。

So that I would be able to open the detail page for each image. If Someone has idea about this please help me.

推荐答案

在必要的图像视图中添加手势识别器：

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);
}
