当点击单元格内的图像时如何获取indexPath

问题描述

我想实现一个功能，如果在 tableviewCell 中点击 profileImage，则转至 detailView.我添加了 tapGesture 但我仍然无法弄清楚如何让 indexPath 传递数据.我试过这样，但应用程序会崩溃.

I would like to implement feature that if profileImage tapped in tableviewCell, segue to detailView. I add tapGesture but I still can't figure out how to get indexPath to pass data. I tried like this but app will crash.

    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {

        if segue.identifier == "detailSegue" {
            let next: DetailViewController = segue.destination as! DetailViewController
          // pattern1
 let indexPath = tableView.indexPath(for: sender as! CustomTableViewCell)
         // pattern2
        let indexPath = tableView.indexPathForSelectedRow! as NSIndexPath

            next.data = datas[indexPath.row]
        }
    }

我该如何解决这个问题?提前致谢！

How can I fix this? Thank you in advance!

推荐答案

1: 在 cellForRowAtIndexpath 方法中设置 ImageView 的标签，标签将等于 indexPath.row

1: set tag of ImageView in cellForRowAtIndexpath method , tag will be equal to indexPath.row

imgView.tag = indexPath.row

2: 添加目标到附加在 imageView 上的 tapGuestureRecognizer

2: add a target to tapGuestureRecognizer attached on imageView

3: 在该方法中获取 imageView 的标签

3: get tag of imageView in that method

let imgView = sender as! UIImageView
let tag = imgView.tag

4:相应地获取数据，并推送

4: get data accordingly ,and push

let next = self.storyBoard.instatiateViewController(WithIdentifer:"detailVC") 
next.data = datas[tag]
self.navigationController.pushViewController(next)
