Loading indicator until tableView loads - ios

Question

I am using Parse to load some data for title , http req for ImageView and ratingView. I also have a segment control view with 2 options.
I put an indicator where the image is presented , but when I scroll down
or when I press another segment(different movies) I get for 1-2 seconds the previous image , ratingView , titles and they change after this instantly. And obviously not all together. Can I somehow sync the changes or give an indicator 'waiting to load' until everything loads ?
func segmentView(segmentView: SMSegmentView, didSelectSegmentAtIndex index: Int) {
self.currentSegmentSelected = index
loadData().findObjectsInBackgroundWithBlock { [weak self] objects, error in
if error == nil {
dispatch_async(dispatch_get_main_queue(), {
self?.loadObjects()
})}
}
}
queryForTable(Parse)
override func queryForTable() -> PFQuery {
let query:PFQuery = PFQuery(className:"Movies")
if(objects?.count == 0)
{
query.cachePolicy = PFCachePolicy.CacheThenNetwork
}
if self.currentSegmentSelected == 0 {
query.whereKey("genres", containsString: "Adventure")
}
else if currentSegmentSelected == 1 {
query.whereKey("genres", containsString: "Comedy")
}
return query
}
cellForRowAtIndexPath
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath, object: PFObject?) -> PFTableViewCell? {
let cellIdentifier:String = "cell"
var cell:TableCell? = tableView.dequeueReusableCellWithIdentifier(cellIdentifier) as? TableCell
if(cell == nil) {
cell = TableCell(style: UITableViewCellStyle.Default, reuseIdentifier: cellIdentifier)
}
//??? indicator.startAnimating()
//??? indicator.backgroundColor = UIColor.whiteColor()
if let pfObject = object {
PFCloud.callFunctionInBackground("averageStars", withParameters: ["movieId":pfObject["movieId"]]) {
(response: AnyObject?, error: NSError?) -> Void in
if let rating = response as! Float? {
cell?.rating.rating = rating
}}
if let movieId = pfObject["movieId"] as? Int {
if RecommendedSet.ratings[movieId] == nil {
cell?.userRating.rating = 0
} else {
cell?.userRating.rating = RecommendedSet.ratings[movieId]!
}
}
cell?.title?.text = pfObject["title"] as? String
if let Id = pfObject["tmdbId"] as? Int {
Alamofire.request(.GET, timdb , parameters: ["api_key": APIkey])
.responseJSON { response in
if let JSON...
let imgData: NSData = NSData(contentsOfURL: imgURL)!
dispatch_async(dispatch_get_main_queue(), {
cell?.posterView?.image = UIImage(data: imgData)
//??? self.indicator.stopAnimating()
//??? self.indicator.hidesWhenStopped = true
})
}}}}}}}
return cell
}
