Question

我有一个tableView，而tableView里面有3个图像。

我希望能够选择一个图像并定向到另一个VC，在那里它显示已被点击的图像。

对于我的图像（从Parse下载）我有一个uuid（唯一标识符），在我使用collectionView之前我将它设置为：

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 .....因为这会明显选择整行，所以我设置了一个像UITapGestureRecognized这样的图像：

 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，我现在还不知道，或者似乎无法弄明白，如何将其连接到唯一的ID ......

我将UUID设置为var = uuidArray =正确下载它们的字符串......

... 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
        }

如果有人能帮我解决这个问题，我会提前感谢你！

最好的问候。

您可以添加indexPath.row作为tapGesture识别器的标记：

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

并将您的功能设置为

func imageTap(sender:AnyObject) {

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

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

选择TableViewCell内部的图像
