Getting images from parse on correct order - swift

Question

I'm trying to get some strings and one photo from parse.com for tableview. I have an NSObject for this class and also an array of object to store them. I can get the newsTitle and the newsDetail in correct order by got fail when try to get newsPhoto. I suppose it lost its order when try get get images in block. Does anybody know what should I change on below code to fix it?
func getNews(){
let query = PFQuery(className: "bulletinOnParse")
query.orderByDescending("createdAt")
query.findObjectsInBackgroundWithBlock {
(allNews: [PFObject]?, error: NSError?) -> Void in
if error == nil {
var duyuru:News
for news in allNews! {
duyuru = News()
let nTitle = news.objectForKey("title") as! String
duyuru.newsTitle = nTitle
let nDetail = news.objectForKey("comment") as! String
duyuru.newsDetail = nDetail
let imageFile = news["newsphoto"] as! PFFile
imageFile.getDataInBackgroundWithBlock {
(imageData: NSData?, error: NSError?) -> Void in
if error == nil {
if let imageData = imageData {
let image = UIImage(data:imageData)
duyuru.newsPhoto = image!
}
}
}
self.bulletin += [duyuru]
}
} else {
// Log details of the failure
print("\(error!.userInfo)")
}
self.tableView.reloadData()
}
}
And cellForRowAtIndexPath method below
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as! DuyuruTableViewCell
self.tableView.rowHeight = 100
let cellInfo = bulletin[indexPath.row]
cell.newsTitle.text = cellInfo.newsTitle
cell.news.text = cellInfo.newsDetail
dispatch_async(dispatch_get_main_queue(), {
cell.newsPhoto.image = cellInfo.newsPhoto
})
return cell
}

Here is the answer of how I solve the problem;
First I created an image array from PFFile object
var resultUserImageFiles = [PFFile]()
Then I get the name and add the array on getNews() method
self.resultUserImageFiles.append(news.objectForKey("newsphoto") as! PFFile)
And I get each photo for cell on below method in cellForRowAtIndexPath method.
self.resultUserImageFiles[indexPath.row].getDataInBackgroundWithBlock { (imageData: NSData?, error:NSError?) -> Void in
if error == nil {
let image = UIImage(data: imageData!)
cell.newsPhoto.image = image
}
}
