title: Getting Facebook username for iOS
body: <p>I'm using the following to get the Facebook username:</p>
  
  <pre><code>    [facebook requestWithGraphPath:@"me" andDelegate:facebook];
  </code></pre>
  
  <p>from my understanding I then have to use something like the following request to </p>
  
  <pre><code>  - (void)request:(FBRequest *)request didLoad:(id)result {
  
    NSLog(@"Result: %@", result);
    NSDictionary *userInfo = (NSDictionary *)result;
    userName = [userInfo objectForKey:@"name"];
    fb_id = [userInfo objectForKey:@"id"];
    }
  </code></pre>
  
  <p>my question is how do I call this request method from another method? </p>
  
  <p>thanks for any help</p>
