I prefer different delegates for each connection, too. Although it's a bit of overhead. Fortunately, you can simplify things by using blocks. It's a new feature that doesn't exist in standard SDK yet, but there is 3rd-party framework called PLBlocks that you can use already. Here is an article on how to use them, it also contains example for NSURLConnection.

This is the client code making HTTP request with block callback:

NSURLRequest *req = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.google.com"]];
[NSURLConnection sendAsynchronousRequest:req onCompletionDo: ^(NSData *data, NSURLResponse *res, NSError *err) {
    NSLog(@"data: %ld bytes. res: %@, error: %@", (long)[data length], res, err);
    [cell.activity stopAnimating];
}];
