获取Facebook用户朋友生日

Question

有没有办法使用iOS Facebook SDK来获取Facebook用户朋友的生日？ 另外，我尝试从用户事件中加载用户朋友的生日，但是我只有事件，而不是生日。

这是我尝试过的代码：

class ViewController: UIViewController {

    let facebookReadPermissions = ["user_events"]

    override func viewDidLoad() {
        super.viewDidLoad()

        if FBSDKAccessToken.currentAccessToken() != nil {
            return
        }

        FBSDKLoginManager().logInWithReadPermissions(self.facebookReadPermissions, handler: { (result:FBSDKLoginManagerLoginResult!, error:NSError!) -> Void in
            if error != nil {
                FBSDKLoginManager().logOut()
                println(error)
            } else if result.isCancelled {
                FBSDKLoginManager().logOut()
                println("cancelled")
            } else {
                var allPermsGranted = true

                let perms = result.grantedPermissions as NSSet
                let grantedPermissions = Array(result.grantedPermissions).map( {"\($0)"} )
                for permission in self.facebookReadPermissions {
                    if !contains(grantedPermissions, permission) {
                        allPermsGranted = false
                        break
                    }
                }
                if allPermsGranted {
                    // Do work
                    println("all perm granted, success!")

                    let fbToken = result.token.tokenString
                    let fbUserID = result.token.userID
                    println(fbToken)
                    println(fbUserID)

                    self.getUserEvents()
                } else {
                    println("failure")
                }
            }
        })
    }

    func getUserEvents() {
        if FBSDKAccessToken.currentAccessToken() != nil {
            FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "events"]).startWithCompletionHandler({ (connection, result, error) -> Void in
                if error == nil {
                    println(result)
                    println("----------------------")
                    println(result as! NSDictionary)
                }
            })
        }
    }
}

输出：

    events =     {
        data =         (
                        {

                        longitude = "32.2676611219";
                        zip = 250;
                    };

                };
                "rsvp_status" = attending;
                "start_time" = "2015-08-30";
            }
        );
        paging =         {

从Facebook api v2.0开始，已删除所有朋友权限。 你不能得到朋友的生日。 参考https://developers.facebook.com/docs/apps/changelog
