The NSConnectionDelegate protocol has a method that pass you the response:
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
You can test if the response is of type NSHTTPURLResponse (which should always be the case when you send an HTTP request), and then use the -[NSHTTPURLResponse statusCode] method to get the status.
