                        for i in 0..<workAr.count {
                            let obj = workAr.objectAtIndex(i) as! NSDictionary

                            var name = ""

工作和教育详细信息权限需要为reviewed在您可以从用户个人资料中获取这些详细信息之前，请访问 Facebook。根据docs :

user_work_history
user_education_history

If your app requests this permission Facebook will have to review how your app uses it.

基本上你必须登录developers.facebook.com并请求 Facebook 审核该特定应用程序的这些权限。 Facebook 将在给予您批准之前审查您的隐私政策和使用条款。只有在此之后，您才能够从您的用户处检索该信息。

我会防御性地验证传入的值，尽管许多人在 Facebook 个人资料上将其留空。确保您考虑了 2 个字段的空/未定义值。
