AFNetworking: setImageWithURLRequest not setting image

Question

I'm trying to set an image on an ImageView using AFNetworking's setImageWithURLRequest on a tableViewCell. If I do not include the success and failure blocks in the method like so:

[cell.thumbnailImageView setImageWithURL:url placeholderImage:nil]; 

Everything works perfectly and the image sets. Unfortunately I need the blocks.

Here's what I currently have in cellForRowAtIndexPath:

if (self.images) { //check if the array of images is set, fetched from a URL

        NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString: [[self.images objectAtIndex:indexPath.row] objectForKey:@"tbUrl"]]];

        [cell.thumbnailImageView setImageWithURLRequest:request placeholderImage:[UIImage imageNamed:@"placeholder"] success:^(NSURLRequest *request, NSHTTPURLResponse *response, UIImage *image) {
                NSLog(@"success"); //it always lands here! But nothing happens
        } failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error) {
                NSLog(@"fail");
        }];

    }

From UIImageView+AFNetworking.h:

If a success block is specified, it is the responsibility of the block to set the image of the image view before returning.

In your success block, you need to say:

[cell.thumbnailImageView setImage: image]
