You use this simple block with your expected requirements

if ([FBSDKAccessToken currentAccessToken])
{
      [[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:nil]
                 startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id user, NSError *error)
       {
           if (!error)
           {
            //  NSDictionary *dictUser = (NSDictionary *)user;
            // This dictionary contain user Information which is possible to get from Facebook account.
           }
        }];
}

Access Token you will get only and only after successfully login

Hope this will help you
