Question

我在线跟踪了一些'指南，但我无法弄清楚如何获取用户的用户名，例如Facebook。登录和会话正常工作。但我不能只取当前用户的值。这是工作代码

 if (!appDelegate.session.isOpen) {
    // create a fresh session object
    appDelegate.session = [[FBSession alloc] init];

    // if we don't have a cached token, a call to open here would cause UX for login to
    // occur; we don't want that to happen unless the user clicks the login button, and so
    // we check here to make sure we have a token before calling open
    if (appDelegate.session.state == FBSessionStateCreatedTokenLoaded) {
        // even though we had a cached token, we need to login to make the session usable
        [appDelegate.session openWithCompletionHandler:^(FBSession *session,
                                                         FBSessionState status,
                                                         NSError *error) {



            NSLog(@"SESSION FACEBOOK OK");

           // how i get username ?

了解如何使用Facebook Graph API。

要求user info：

[FBRequestConnection startForMeWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
   if (!error) {
      // Success! Include your code to handle the results here
      NSLog(@"user info: %@", result);
   }  else {
      // An error occurred, we need to handle the error
      // See: https://developers.facebook.com/docs/ios/errors   
   }
}];
