title: Objective-C get the number of twitter followers
body: <p>I am trying to get the number of twitter followers in my iOS App.</p>
  
  <p>I find some Documentation regarding this issue:
  <a href="https://dev.twitter.com/rest/reference/get/users/lookup" rel="nofollow">https://dev.twitter.com/rest/reference/get/users/lookup</a></p>
  
  <p>This is the code I have so far:</p>
  
  <pre><code>    NSString *apiURLString = [NSString stringWithFormat:@"https://api.twitter.com/1.1/users/lookup.json?screen_name=%@", @"barackobama"];
  
      NSURL *apiURL = [NSURL URLWithString:apiURLString];
  
      NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:apiURL];
  
      request.HTTPMethod = @"GET"; 
  
      NSOperationQueue *queue = [[NSOperationQueue alloc] init];
  
      [NSURLConnection sendAsynchronousRequest:request queue:queue completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {
  
  //        ((NSHTTPURLResponse *)response).statusCode
  
          NSLog(@"response = %@", response);
      }];
  </code></pre>
  
  <p>However, I am pretty confused as how to send all the other parameters required for the request.</p>
  
  <p>Thanks in advance!</p>
