Question

例如，我正在使用Facebook API获取我的个人资料：

[FBRequestConnection startWithGraphPath:@"/me"
                             parameters:nil
                             HTTPMethod:@"GET"
                      completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
    NSLog(@"RESULT: %@", result);
}];

我该如何回应：

2014-10-21 16:45:40.435 FacebookTestApp[***] RESULT: {
    "first_name" = Richard;
    gender = male;
    id = *********************;
    "last_name" = Topchiy;
    link = "https://www.facebook.com/app_scoped_user_id/******/";
    locale = "en_US";
    name = "Richard Topchiy";
    timezone = 3;
    "updated_time" = "2014-05-20T17:34:52+0000";
    verified = 1;
}

我可以访问这样的数据：

  FBGraphObject *obj = (FBGraphObject *)result;
  NSString *str = obj[@"first_name"];

但有没有办法使用这样的API：

FBGraphObject *obj = (FBGraphObject *)result;
NSString *name = obj.first_name;

我在官方文档中没有找到这个，我无法创建＆＃34; FBGraphUser＆＃34;。我做错了什么，或Facebook已禁用此功能？

FBGraphUser是一种协议。所以你可以做到以下几点： FBGraphObject<FBGraphUser> *user = (FBGraphObject<FBGraphUser>*)result;
