title: Prompt login alert with Twitter framework in iOS5?
body: <p>As you all may know, since iOS5 there is a native Twitter framework which make it easy to post tweets from your app. </p>
  
  <p>Is there a way to prompt an alert that forwards the user to the settings app and ask for username and password?</p>
  
  <p>I know that i could solve the problem with the following code:</p>
  
  <pre><code>[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=TWITTER"]];
  </code></pre>
  
  <p>But thats undocumented code..</p>
  
  <p>Thanks in advance</p>
