FIRMessagingDelegate 的消息：didReceiveMessage：未实现 - Firebase 4.1.1 - Swift 3

Question

我将 Firebase 从 v3 升级到 v4，但我在接收消息时遇到了一些问题，我收到了这个警告：

[Firebase/Messaging][I-FCM002019] FIRMessaging received data-message, but FIRMessagingDelegate's-messaging:didReceiveMessage: not implemented

我知道我应该实现这个方法：

public func messaging(_ messaging: Messaging, didReceive remoteMessage: MessagingRemoteMessage){
    print(remoteMessage.appData)
            //let title = remoteMessage.appData[("data"): {"title"}]
           var title = "New Request"

            for value in remoteMessage.appData{
                if let value = value as?  [AnyHashable:Any]{
                print(value)
                }
            }
            let message = "okay"
            print(message)
             self.showAlertAppDelegate(title: title ,message:message ,buttonTitle:"ok",window:self.window!)
            print(title, message)

}

但我仍然收到警告，请问我还应该做些什么吗？

我发现了问题，就是我忘记了这一行

Messaging.messaging().delegate = self

在这个方法中：

func application(_ application: UIApplication,
               didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {}
