ios - UITableView loading Issues with images -

I have set up my application to use parse. I am uploading the image when the request is sent for parsing So it stores all of my objects in an array 'wallObjectsArray', although images are the problems they display when I see them in their UITableview. It was initially shown that by then nothing will disappear until I refresh UITableView. I used SDWebImage before but I did not think I would need it with it because all the images have already been stored in my array, I just want to display them and easily scroll through the UITableView Want to do I am using a custom class class in my code below

  self.customCell = [tableView dequeueReusableCellWithIdentifier: @ "cell"]; PFObject * wallObject = [self.wallObjectsArray objectAtIndex: indexPath.row]; _image = (PFFile *) [wallObject objectForKey: @ "image"]; Self.customcell.profileImageView.image = [UIImage imageWithData: _image.getData];
