Alright. Solved. You gave me the wrong JSON file ;)

    NSString *username = [_photo valueForKeyPath:@"caption.from.username"];

Try something like this if you do it in photoCell.m and override the setter:

- (void)setPhoto:(NSDictionary *)photo
{
    _photo = photo;
    NSString *username =     [_photo[@"username"] stringValue];
}

Thanks for your comment.

However, when i do an NSLog on username the result is (null)

That sounds reasonable, because "_photo" is a dictionary containing JSON. You have to see where in the JSON-file username is displayed. Post a picture of the JSON and I can help you further :)
