ios - 选择 UITableViewCell 内的图像

Question

我有一个 tableView，该 tableView 内部有 3 个图像。

我希望能够选择一个图像并定向到另一个 VC，在其中显示已点击的图像。

对于我的图像(从 Parse 下载)，我有一个 uuid(唯一标识符)，之前当我使用 collectionView 时，我将其设置如下:

func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) {
        postuuid.append(uuidArray[indexPath.row])

        let post = self.storyboard?.instantiateViewControllerWithIdentifier("collectionImage") as! CollectionImageViewController
        self.navigationController?.pushViewController(post, animated: true)
    }

这让我得到了我现在想要实现的目标......

我意识到我不能使用 TableView SelectedRow..... 因为这显然会选择整行，所以我设置了一个图像 UITapGestureRecognized，如下所示:

 let imageTap = UITapGestureRecognizer(target: self, action: "imageTap")
            imageTap.numberOfTapsRequired = 1
            imageView.userInteractionEnabled = true
            imageView.addGestureRecognizer(imageTap)

然后使用 func() 将其重定向到新的 VC:

 func imageTap() {

        postuuid.append// My issues here, I'm not sure how to set it up or reference it to the cellForRow, like I did it in the collectionViewSelected item code above.

        let post = self.storyboard?.instantiateViewControllerWithIdentifier("collectionImage") as! CollectionImageViewController
        self.navigationController?.pushViewController(post, animated: true)
    }

正如您从我的代码中看到的那样，我不知道，或者目前似乎无法弄清楚，如何将其连接到唯一 ID...

我将 UUID 设置为 var = uuidArray = String ，它正在正确下载它们...

CellForRow...:

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
     {
        var counter = (indexPath.row * 3)

      let cell = tableView.dequeueReusableCellWithIdentifier("cell") as! ProfileTableViewCell




        for imageView in cell.threeImages {
            imageView.image = UIImage(named: "ImagePlaceHolder")

            if counter < imageArray.count {
            imageView.hidden = false
            let finalImage = imageArray[counter++]["image"]
            finalImage!.getDataInBackgroundWithBlock {
                (imageData: NSData?, error: NSError?) -> Void in
                if error == nil {
                    if let imageData = imageData {
                        imageView.image = UIImage(data:imageData)

                    }}}} else {
                imageView.hidden = true
            }



           let imageTap = UITapGestureRecognizer(target: self, action: "imageTap")
            imageTap.numberOfTapsRequired = 1
            imageView.userInteractionEnabled = true
            imageView.addGestureRecognizer(imageTap)


return cell
        }

如果有人可以帮助我解决这个问题，我提前非常感谢!

致以诚挚的问候。

您可以添加indexPath.row作为tapGesture识别器的标签:

...
let imageTap = UITapGestureRecognizer(target: self, action: "imageTap:")
imageView.tag = indexPath.row
...

并将您的函数设置为

func imageTap(sender:AnyObject) {

    postuuid.append(uuidArray[sender.view.tag])

    let post = self.storyboard?.instantiateViewControllerWithIdentifier("collectionImage") as! CollectionImageViewController
    self.navigationController?.pushViewController(post, animated: true)
}
