Retrieve Profile Image

I am trying to retrieve user profile image from parse. I have a collection view and I am retrieving all images people posted. I want to show each users profile image in the cell as well. I was using the below code override func viewDidLoad() { super.viewDidLoad()

    let query = PFQuery(className: "Posts")
    query.includeKey("pointName")
    query.findObjectsInBackgroundWithBlock{(question:[AnyObject]?,error:NSError?) -> Void in

        if error == nil
        {
            if let allQuestion = question as? [PFObject]
            {
                self.votes = allQuestion
                self.collectionView.reloadData()
            }
        }
    }


    // Wire up search bar delegate so that we can react to button selections

    // Resize size of collection view items in grid so that we achieve 3 boxes across

    loadCollectionViewData()
}

/*
==========================================================================================
Ensure data within the collection view is updated when ever it is displayed
==========================================================================================
*/

// Load data into the collectionView when the view appears
override func viewDidAppear(animated: Bool) {
    loadCollectionViewData()
}

/*
==========================================================================================
Fetch data from the Parse platform
==========================================================================================
*/

func loadCollectionViewData() {
    // Build a parse query object
}

/*
==========================================================================================
UICollectionView protocol required methods
==========================================================================================
*/

func numberOfSectionsInCollectionView(collectionView: UICollectionView) -> Int {
    return 1
}

func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
    return self.votes.count
}



func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {

    let cell = collectionView.dequeueReusableCellWithReuseIdentifier("newview", forIndexPath: indexPath) as! NewCollectionViewCell
    let item = self.votes[indexPath.row]





    // Display "initial" flag image
    var initialThumbnail = UIImage(named: "question")
    cell.postsImageView.image = initialThumbnail

    if let pointer = item["uploader"] as? PFObject {
        cell.userName!.text = item["username"] as? String
        print("username")

    }

    if let profile = item["uploader"] as? PFObject,
        profileImageFile = profile["profilePicture"] as? PFFile {
            cell.profileImageView.file = profileImageFile
            cell.profileImageView.loadInBackground { image, error in
                if error == nil {
                    cell.profileImageView.image = image
                }
            }
    }

    if let votesValue = item["votes"] as? Int
    {
        cell.votesLabel?.text = "\(votesValue)"
    }

    // Fetch final flag image - if it exists
    if let value = item["imageFile"] as? PFFile {
        println("Value \(value)") 
        cell.postsImageView.file = value
        cell.postsImageView.loadInBackground({ (image: UIImage?, error: NSError?) -> Void in
            if error != nil {
                cell.postsImageView.image = image
            }
        })
    }

    return cell
}

However I found out that it sets profile image to the current user and not the user who posted the image. How can I do this? Thank you

UPDATE

so In parse my post class is enter image description here

so I know who uploaded it but I don't know how to retrieve the profile image for this specific user.

You need to use a pointer that will point to the user who created the object. The profile photo should be in the user class. You then include the pointer in your query and that will return the user data.

okay, this might help you in objective-C 

PFUser *user = PFUser *user = [PFUser currentUser]; 
[user fetchIfNeededInBackgroundWithBlock:^(PFObject *object, NSError *error) {
 _profileImage.file = [object objectForKey:@"profilePicture"]; 
}];
