Swift 2.0：需要在 Parse 的 PFQueryTableViewController 上显示图像（PFFile）？

Question

我正在尝试将图像（文件）从 Parse 检索到 PFQueryTableViewController。我在下面写了我的代码。我认为这是正确的，但我可能缺少一些小东西。我想看到图像显示，但我只看到图像应该是空白的地方。图像也在 Parse 中。我以前尝试过这个实例并且它有效，但由于某种原因，我看不到它在这里适用于这种情况。那么如何从解析中检索图像以显示在查询中？

    let query = PFQuery(className: "Test")

    if let query = profilePage {

        pencil = NSMutableArray()

        query.addAscendingOrder("createdAt")

        query.findObjectsInBackgroundWithBlock {(objects: [AnyObject]?, error: NSError?) -> Void in

            if error == nil {               
                for object in objects! {

                    let pencil : PFObject = object as! PFObject
                    self.pencil.addObject(pencil)                 
                }

                let array : NSArray = self.pencil.reverseObjectEnumerator().allObjects

                self.pencil = NSMutableArray(array: array)

                self.tableView.reloadData()

            } else {


            }
        }

    }
}
        override func tableView(tableView: UITableView?, cellForRowAtIndexPath indexPath: NSIndexPath?, object: PFObject!) -> PFTableViewCell? {
       let cell = tableView!.dequeueReusableCellWithIdentifier("TakerCell", forIndexPath: indexPath!) as! TestTaker


        if let uTest : PFObject = self.pencil.objectAtIndex(indexPath!.row) as! PFObject {
        cell.testWriter.text = posts["taker"] as? String
        cell.testInfo.text = posts["information"] as? String
        if let photo = object["picture"] as? PFFile {
        let PFimageV = cell.userImg as PFImageView
        PFimageV.image = UIImage(named: "userImage")
        PFimageV.file = photo
        PFimageV.layer.cornerRadius = imageView.frame.width/2
        PFimageV.clipsToBounds = true
        PFimageV.loadInBackground()

            }

            }

这里是如何使用普通查询从 Parse 中获取图像（您可以添加自己的 whereKeys）...

    let query = PFQuery(className: "Your Class Name")
    query.findObjectsInBackgroundWithBlock { (objects, error) -> Void in
        if let objects = objects as? [PFObject] {
            for object in objects {
                self.imagesArray.append(UIImage(data: object["image"]!.getData()!)!)

            }

        }

    }
