title: FBLikeControl does not load nor function
body: <p>With the new release of facebook ios sdk, the documentation is talking about the facebook like control, that allows to like a page.
  <a href="https://developers.facebook.com/docs/ios/like-button/" rel="nofollow">https://developers.facebook.com/docs/ios/like-button/</a></p>
  
  <p>the documentation of the control is here 
  <a href="https://developers.facebook.com/docs/reference/ios/current/class/FBLikeControl" rel="nofollow">https://developers.facebook.com/docs/reference/ios/current/class/FBLikeControl</a></p>
  
  <p>Yet i tried it and it's not appearing, though i can detect a clear color rectangle only, i change the background color, the color appears on that rectangle, but not the facebook style as mentioned in the documentation.
  Additionally it doesn't work, it should take me to the fb app to show the object linked to it.</p>
  
  <p>I tried through an app, while configuring the project as mentioned, AppID ... and everything. I tried also from a sample project "SessionLoginSample" that comes with facebook SDK, to no avail.</p>
  
  <p>The button being clear color, seems like intentional, or something broken. 
  It's new so I thought that there might be problems, or, i'm doing something wrong :) </p>
  
  <p>Anybody?</p>
