如何在 ios 10 中从 FBGraphApi 的结果中提取数据

Question

在 Swift 2.2 和 iOS 9 之前它可以完美运行，但在 Swift 3.0 中进行更改后，我无法获取姓名、电子邮件和 fbid。这是因为结果来自任何并且无法从结果中提取数据。在 swift 3.0 中转换后，我的代码如下所示

 func signInWithFB(_ forVC:UIViewController , sucess:@escaping signInSuccessBlock , falure:@escaping SignInFailureBlock)
        {
            let obj_facebook = FBSDKLoginManager()
            obj_facebook.loginBehavior = .native
            obj_facebook.logIn(withReadPermissions: ["public_profile","email","user_friends"], from: forVC) { (result:FBSDKLoginManagerLoginResult?, error:Error?) -> Void in
                if ((error) != nil)
                {
                    falure(error as NSError?, false)
                }
                else if ((result?.isCancelled) == true)
                {
                    falure(nil, true)
                }
                else
                {

                    let dicLoginData = NSMutableDictionary()
                    let request = FBSDKGraphRequest(graphPath: "/me?fields=name,email,gender,hometown,education,location,first_name,last_name", parameters: nil)
                    let _ =
                    request?.start(completionHandler: { (Connection:FBSDKGraphRequestConnection?, result:Any!, error:Error?) -> Void in

                        if error == nil
                        {

                            dicLoginData.setValue((result as AnyObject).value(forKey: "name"), forKey: "name")
                            dicLoginData.setValue((result as AnyObject).value(forKey: "email"), forKey: "email")
                            dicLoginData.setValue((result as AnyObject).value(forKey: "gender"), forKey: "Gender")
                            dicLoginData.setValue((result as AnyObject).value(forKey: "last_name"), forKey: "lname")
                            dicLoginData.setValue((result as AnyObject).value(forKey: "first_name"), forKey: "fname")
                            let faceBookID:String = (result as AnyObject).value(forKey: "id") as! String
                            let proPicUrl = String(format:"https://graph.facebook.com/%@/picture?type=large", faceBookID)
                            dicLoginData.setValue(faceBookID, forKey: "facebookId")
                            dicLoginData.setValue(proPicUrl, forKey: "proPicURL")
                            //                    dicLoginData.setValue(strLoaction?.first, forKey: "City")


                            sucess(dicLoginData)
                        }
                       else
                        {
                            falure(error as NSError?, false)
                        }

                    })

                }
            }
        }

Answer 1

将result 对象的类型指定为[String: Any]，而不是在swift 中使用value(forKey:) 和setValue(_:forKey) 使用下标和Dictionary，如result["name"]，所以进行这样的更改。

if let fbDic = result as? [String: Any] {
    dicLoginData["name"] = fbDic["name"] 
    //and so on
}

注意：如果您使用 Swift 的通用 Dictionary 和 Array 对象而不是 NSDictionary/NSArray，则在 Swift 连击中。
