title: FBLoginView rejects some users
body: <p>I am using the newest Facebook iOS SDK in my project. I have successfully implemented Facebook login using FBLoginView following their own guide:
  <a href="https://developers.facebook.com/ios/login-ui-control/" rel="nofollow">https://developers.facebook.com/ios/login-ui-control/</a></p>
  
  <p>This works for most people, however some people are experiencing that they can't login - receiving an error message saying that they need to accept the needed permissions in order to login. Even though they clearly accept these permissions!</p>
  
  <p>I use the same error handling as in the example at the above link (near the bottom of the page) and it seems like the error of type FBErrorCategoryUserCancelled is being triggered.</p>
  
  <p>I cant simulate the error on any of my Facebook accounts neither on the simulator nor my iPhone. However multiple people are experiencing this problem without having anything significant in common. What should I do?</p>
  
  <p><strong>Update April 24</strong></p>
  
  <p>My <code>WelcomeViewController</code> is the view who handles the Facebook login. In the <code>.m</code> file I have the following code for handling permissions:</p>
  
  <pre><code>- (void)viewDidLoad
  {    
      [super viewDidLoad];
  
      // Facebook login permissions
      loginView.readPermissions = @[@"email"];
      loginView.publishPermissions = @[@"publish_actions"];
      loginView.defaultAudience = FBSessionDefaultAudienceFriends;
  
  }
  </code></pre>
  
  <p><strong>Update April 24 part 2</strong></p>
  
  <p>With the help from my testers I have localized the problem. Everyone who experiences the login problem has integrated Facebook with iOS - that is they are logged in with Facebook on their iOS (Under Settings->Facebook). As soon as this is disabled - they can log in. Is this a bug in the SDK or how can I handle this?</p>
