To disable this behavior modify Facebook.m line 275 and set both options to NO.

- (void)authorize:(NSArray *)permissions {
  self.permissions = permissions;

  // with both options NO, authorization always happens in-app
  [self authorizeWithFBAppAuth:NO safariAuth:NO];
}

In your app delegate you need to implement (make sure you keep a reference to the facebook class instance somewhere where it can be accessed by your app delegate):

- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url 
{
    return [facebook handleOpenURL:url];
}
