Google登錄IOS Swift 4 AppDelegate錯誤

Question

我正在嘗試實現Google登錄以及可使用的Linkedin和Facebook登錄。

我嘗試按照文檔進行集成。 我用cocoapods安裝了Pod，編輯了info.plist，現在我正在添加AppDelegate方法。

以下代碼段給了我這個錯誤：

無法使用索引類型為“ UIApplicationOpenURLOptionsKey”的下標“ [String：AnyObject]”的值

碼：

func application(application: UIApplication,
                 openURL url: NSURL, options: [String: AnyObject]) -> Bool {

    return GIDSignIn.sharedInstance().handleURL(url as URL!,
                                                sourceApplication: options[UIApplicationOpenURLOptionsSourceApplicationKey] as? String,
                                                annotation: options[UIApplicationOpenURLOptionsAnnotationKey])
}

首先，編譯器似乎無法識別“ UIApplicationOpenURLOptionsSourceApplicationKey”是什么，這可能是解決方案的一個提示。

文檔恰好顯示了這一點，所以我很堅持。 不確定如何使此委托方法起作用。

這是我完整的AppDelegate代碼：

您需要使用此簽名實現這兩種方法

func application(_ app: UIApplication,
                 open url: URL,
                 options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool
  {
     if #available(iOS 9.0, *) {

           return GIDSignIn.sharedInstance().handle(url,sourceApplication:options[UIApplicationOpenURLOptionsKey.sourceApplication] as? String,  annotation: [:])

     }

   return true

}

public func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {

    return  GIDSignIn.sharedInstance().handle(url,sourceApplication: sourceApplication, annotation: annotation)

}
