json - 从 Facebook sdk 获取个人资料图片 url

Question

我找不到获取 Facebook 个人资料图片网址的解决方案。

当我通过 Facebook 登录时，我使用此方法通过 Facebook graph api 获取个人资料信息:

func getFBUserData() {
    // Create request for user's Facebook data
    let request = FBSDKGraphRequest(graphPath:"me", parameters:["fields": "id, name, first_name, middle_name, last_name, email, picture.type(large)"])

    // Send request to Facebook
    request.startWithCompletionHandler {

        (connection, result, error) in

        if error != nil {
            // Some error checking here
        }
        else {

            print(result)


            if let userData = result as? [String:AnyObject] {

                // Access user data
                let username = userData["first_name"] as! String


            }

        }

    }
}

我可以轻松解析名字、电子邮件等，但当涉及到图片网址时，我不知道如何影响该数据。以下是我对 Facebook api 的回复:

{
    email = "dailocle@hotmail.com";
    "first_name" = Loc;
    id = 123456765432457654;
    "last_name" = Le;
    "middle_name" = Dai;
    name = "Loc Dai Le";
    picture =     {
        data =         {
            "is_silhouette" = 0;
            url = "https://scontent.xx.fbcdn.net/hprofile-xat1/v/t1.0-1/p200x200/12246670_10207807554127440_7406917875415466413_n.jpg?oh=d394b200091f8973645300054e6b32b8&oe=572E6626";
        };
    };
}

使用 FBSDKProfile 类的 imageURLForPictureMode:size 便捷方法。

let pictureURL = FBSDKProfile().imageURLForPictureMode(.Normal, size: CGSize(width: 100, height: 100))
