Google didSignInForUser不会迅速启动3

Question

我正在Google中登录我的项目。我使用CocoaPods安装了SDK。我有以前用Objective-C编写的这个相同的应用程序。所以我从我的旧项目中拖动了相同的Google配置文件（GoogleService-Info.plist）。

而且我跟着this with CocoaPods installed method。但是当我按下登录按钮时，我正在指向Google网页，输入用户名密码后，它会返回到我的应用程序。但是这个代表没有触发。

func signIn(signIn: GIDSignIn!, didSignInForUser user: GIDGoogleUser!, withError error: NSError!) { 
    if error == nil { 
     // Perform any operations on signed in user here. 
     let userId = user.userID     // For client-side use only! 
     let idToken = user.authentication.idToken // Safe to send to the server 
     let fullName = user.profile.name 
     let givenName = user.profile.givenName 
     let familyName = user.profile.familyName 
     let email = user.profile.email 
     let dm = Datamanager.sharedInstance 
     dm.gplusEmail = email 
     NotificationCenter.default.post(name: NSNotification.Name(rawValue: "RETURNED_GOOGLE"), object: nil) 
     // ... 
    } else { 
     print("\(error.localizedDescription)") 
    } 
} 

我在按钮的标志是一个UIButton，在我的ViewController我这样已经实现：

@IBAction func googleClick(_ sender: UIButton) { 
    strLoggedWay="google" 
    GIDSignIn.sharedInstance().signIn() 
} 

请帮助我。我的代码过程出了什么问题？

//In your login view controller 

@IBAction func googleClick(_ sender: UIButton) { 

    strLoggedWay="google" 

    GIDSignIn.sharedInstance().clientID = //getGoogleClientId 
    GIDSignIn.sharedInstance().serverClientID = //getGoogleServerClientId 
    GIDSignIn.sharedInstance().uiDelegate = self 
    GIDSignIn.sharedInstance().delegate = self 
    GIDSignIn.sharedInstance().scopes = @["https://www.googleapis.com/auth/userinfo.profile","https://www.googleapis.com/auth/userinfo.email"] 
    GIDSignIn.sharedInstance().signIn() 
} 

func signIn(signIn: GIDSignIn!, didSignInForUser user: GIDGoogleUser!, 
      withError error: NSError!) { 
    if (error == nil) { 
     // Perform any operations on signed in user here. 
     let userId = user.userID     // For client-side use only! 
     let idToken = user.authentication.idToken // Safe to send to the server 
     let fullName = user.profile.name 
     let givenName = user.profile.givenName 
     let familyName = user.profile.familyName 
     let email = user.profile.email 
     let dm=Datamanager.sharedInstance 
     dm.gplusEmail=email 
     NotificationCenter.default.post(name: NSNotification.Name(rawValue: "RETURNED_GOOGLE"), object: nil) 
     // ... 
    } else { 
     print("\(error.localizedDescription)") 
    } 
}
