iOS Facebook SDK错误代码5获取用户信息

我正在尝试做一些原始的基础工作来获取Facebook的用户凭据。这是我的密码：

[FBSession openActiveSessionWithReadPermissions:@[@"basic_info"] allowLoginUI:NO
                              completionHandler:
 ^(FBSession *session, FBSessionState state, NSError *error) {

     [FBSession setActiveSession:session];
     if (FBSession.activeSession.isOpen){
        //Success

       [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
                 }
             }];
     }
     else{
         //Prompt for login
     }
 }];

每当我到达

FBRequestConnection

completion hander时，我都会得到错误代码5。我在这里尝试过这个解决方案，但没有成功：。

没关系。事实证明，你需要通过手机上网才能访问FacebookFacepalm
