Question

下面的代码不会从登录中提取user.username。我也试过Facebook sdk你好Facebook，它仍然没有抓住user.username。奇怪的是，它曾经在某个时刻使用过。我的部分代码如下。请指教。

- (void)loginViewFetchedUserInfo:(FBLoginView *)loginView
                            user:(id<FBGraphUser>)user {
    // here we use helper properties of FBGraphUser to dot-through to first_name and
    // id properties of the json response from the server; alternatively we could use
    // NSDictionary methods such as objectForKey to get values from the my json object
    self.labelFirstName.text = [NSString stringWithFormat:@"Hello %@!", user.first_name];
    // setting the profileID property of the FBProfilePictureView instance
    // causes the control to fetch and display the profile picture for the user
    self.profilePic.profileID = user.id;
    self.loggedInUser = user;
    FitGoalAppDelegate *appDelegate = (FitGoalAppDelegate *)[[UIApplication sharedApplication] delegate];
    appDelegate.uname = nil;
    appDelegate.uname = user;
    appDelegate.lastname = user.last_name;
    appDelegate.firstname = user.first_name;
    NSLog(@"First Name=%@",appDelegate.firstname);
    NSLog(@"Last Name=%@",appDelegate.lastname);
    NSLog(@"Real Userbame %@",user.username);
    NSLog(@"Copied Userbame %@",appDelegate.uname.username);
}

Answer 1

Facebook API v2.0中没有用户名

Answer 2

但是你可以使用一个技巧。收到ID后，您可以拨打此https://graph.facebook.com/ {user_id}之类的电话，您将获得包含用户名的用户的元数据。
