title: Facebook Graph API: Resume Session on iPhone
body: <p>I have been playing with the Facebook Graph API since yesterday and it is pretty good, however, I have been searching around the web for some method of resuming a session. That is, once a user has gone through the authentication (of allowing an app to use their data), logging in automatically when they open the app (or even providing a login button).</p>
  
  <p>I have found plenty of posts on FBSession and using [session resume]. The problem is, these have been removed. What is the new method of resuming a users session and logging in?</p>
