title: Get http response code in ios when using sendSynchronousRequest
body: <p>I have a working http GET without using any third party bits, I am new to iOS so this was a struggle to setup initially. My code looks like:</p>
  
  <pre><code>-(NSString *) SendGetRequestToRest:(NSString *)urlEndString
  {
  
  NSString *userName = @"userN";
  NSString *password = @"PassW";
  
  NSString *urlBaseString = @"http://someurl.co.uk/";
  
  NSString *urlString = [NSString stringWithFormat:@"%@%@", urlBaseString, urlEndString];
  
  NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
  
  [request setURL:[NSURL URLWithString:urlString]];
  
  [request setHTTPMethod:@"GET"];
  
  NSString *str1 = [NSString stringWithFormat:@"%@:%@", userName, password];
  NSString *encodedString = [self stringByBase64EncodingWithString:str1];
  [request addValue:[NSString stringWithFormat:@"Basic %@",encodedString] forHTTPHeaderField:@"Authorization"];
  
  NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
  
  NSString *str = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
  NSLog(@"str: %@", str);
  
  return str;
  
  }
  </code></pre>
  
  <p>What I need to do is track when the status code of the http GET is not a nice 200, I saw <a href="https://stackoverflow.com/questions/12238377">How to check status of web server in iOS?</a> and this looks promising i.e. add this:</p>
  
  <pre><code>-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSHTTPURLResponse *)response
  {
      if ([response statusCode] == 404)
      {
      /// do some stuff
      }
  }
  </code></pre>
  
  <p>But I cant see how to connect this up to</p>
  
  <pre><code>NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
  </code></pre>
  
  <p>as it doesnt accept a delegate?</p>
