swift – 通过Firebase登录Google：GIDSignInDelegate不符合ViewController

这是Firebase guide和Google guide:

所以

>将Google添加到podfile – checK
>在Bridging-Header中添加了行 – checK
>添加了Googleservice-Info.plist&捆绑标识符&将客户端ID反转为URL方案 – 检查
> App Delegate有以下@L_262_9@,没有错误,但我注意到Facebook登录(正常工作)和新Google之间可能存在冲突,我不知道如何一起处理：

附：我没有在这里向AppDelegate添加GIDSignInDelegate,因为我正计划让我的VC处理登录逻辑,如下所示……
> LoginVC ViewController代码：

class LoginVC: UIViewController,UIViewControllerTransitioningDelegate,UITextViewDelegate,UITextFieldDelegate,GIDSignInDelegate,GIDSignInUIDelegate {

    override func viewDidLoad() {
    super.viewDidLoad()
    let ref = Firebase(url: "https://MYAPPID.firebaseio.com")
    GIDDSignIn.sharedInstance().delegate = self
    GIDSignIn.sharedInstance().uiDelegate = self
    GIDSignIn.sharedInstance().signInSilently()  // for if the user has recently been authenticated
    }

然后,从我所看到的……应该是Google需要与Firebase交流的所有@L_262_9@：

// ImplemenTing the required GIDSignInDelegate methods
        func googleSignIn(signIn: GIDSignIn!,didSignInForUser user: GIDGoogleUser!,withError error: NSError!) {
            if (error == nil) {
                // Auth with Firebase
                let userId = user.userID
                let idToken = user.authentication.idToken
                let fullName = user.profile.name
                let givenName = user.profile.givenName
                let familyName = user.profile.familyName
                let email = user.profile.email
                ref.authWithOauthprovider("google",token: user.authentication.accessToken,withCompletionBlock: { (error,authData) in
                    // User is logged in!
                })
            } else {
                print("\(error.localizedDescription)")
            }
        }


        func googleSignOut() {
            GIDSignIn.sharedInstance().signOut()
            ref.unauth()
        }

        // Implement the required GIDSignInDelegate methods and Unauth when disconnected from Google
        func signIn(signIn: GIDSignIn!,didDisconnectWithUser user:GIDGoogleUser!,withError error: NSError!) {
            ref.unauth()
        }


        // IBACtion to handle the sign-in process
        @IBACtion func googleButtonPressed(sender: TKTransitionSubmitButton!) {
            GIDSignIn.sharedInstance().signIn()
        }

百思不得其解？很抱歉这些人很久……但我已经完成了Firebase指南建议的所有@L_262_9@,这意味着AppDelegate的Google文档中的逻辑就在ProfileVC中.有什么指针吗？
