AFNetworking and UIImageView updating threading issues
===

So I have a UITableView with a custom UITableViewCells and inside my custom cell I have a UIImageView in which I use AFNetworking category's to load the image:

    NSString *imageURLString = [[object.image_ valueForKey:@"low_resolution"] valueForKey:@"url"];
        NSURLRequest *imageURLRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:imageURLString] cachePolicy:NSURLRequestReturnCacheDataElseLoad timeoutInterval:30];
        [self.imageView_ setImageWithURLRequest:imageURLRequest andAnimate:YES placeholderImage:nil success:^(NSURLRequest *request, NSHTTPURLResponse *response, UIImage *image){
    
        }failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error){
            NSLog(@"FAILED");
        }];

The issue is that, sometimes when you scroll down.. it seems there's a long delay until the image request is triggered. I am testing in a very good connection. Why is this happening?
