Downloading a PFFile(image) into the backgroundImage of a cell?

I've already saved the photo to Parse using

NSString *filename = [NSString stringWithFormat:@"%@.png", _nameText.text];
        PFFile *imageFile = [PFFile fileWithName:filename data:imageData];
        //[shoePic setObject:imageFile forKey:@"Image"];


        PFObject *jordanObject = [PFObject objectWithClassName:@"Jordans"];
        jordanObject[@"jordanName"] = filename;
        jordanObject[@"jordanImage"] = imageFile;
        [jordanObject saveInBackground];

of course Im using the saveInBackgroundWithBlock but for brevity in the context of this question it creates a table with a column for the imageFile, with the column title referencing the string literal above.

How can i retrieve this file and set it as the backgroundImage of my collectionview cell.

i've used this in cellForItemAtIndexPath:

 PFQuery *query = [PFQuery queryWithClassName:@"Jordans"];
        //[query orderByAscending:@"jordanName"];
        [query getObjectInBackgroundWithId:[self.shoe.jordanShoeNames objectAtIndex:0] block:^(PFObject *jordanObject, NSError *error) {
            // Do something with the returned PFObject in the JordanObject variable.

            jordanObject = [PFObject objectWithClassName:@"Jordans"];

            PFFile *imageFile = jordanObject[@"jordanImage"];
            [imageFile getDataInBackgroundWithBlock:^(NSData *imageData, NSError *error) {
                if (!error) {
                    UIImage *image = [UIImage imageWithData:imageData];
                    NSLog(@"the data: %@", imageData);

                    cell.jordanShoePhoto.image = image;
                }
            }];

but i keep getting a nil JordanObject, by the way, the array passed into the block holds the objectID geneated by parse for the image.
