title: facebook iphone - how login under different user
body: <p>I'm making a game for iphone, so my question:
  How is the end user supposed to change his login. Meaning if he decides to log in under a different name?</p>
  
  <p>I noticed that even a resetting of the phone and reinstalling the app doesn't work, I'm still logged in under the same user as before.
  My next guess was FB.Logout, but this page tells me not to use it:
  <a href="https://developers.facebook.com/docs/unity/reference/current/FB.Logout" rel="nofollow">https://developers.facebook.com/docs/unity/reference/current/FB.Logout</a></p>
  
  <p>And also, under Settings -> Facebook I logged into another user already, too - in my game it's still using the old user...</p>
