未在ios 10上收到Firebase通知

Question

我正在iOS中使用Firebase實施推送通知。不幸的是，我遇到了Firebase未收到通知的問題。

這是我得到的輸出中的錯誤：

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

請問該如何解決這個問題？我已經在iOS 9.3上測試過它，它工作正常。我使用下面的代碼：

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool 
    { 
     FirebaseApp.configure() 
     if #available(iOS 10.0, *) { 
      // For iOS 10 display notification (sent via APNS) 
      UNUserNotificationCenter.current().delegate = self 

      let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound] 
      UNUserNotificationCenter.current().requestAuthorization(
       options: authOptions, 
       completionHandler: {_, _ in }) 
     } 
     else 
     { 
      let settings: UIUserNotificationSettings = UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil) 
      application.registerUserNotificationSettings(settings) 
     } 
     application.registerForRemoteNotifications() 
     // Add observer for InstanceID token refresh callback. 
     NotificationCenter.default 
      .addObserver(self, selector: #selector(AppDelegate.tokenRefreshNotification), 
         name: NSNotification.Name.InstanceIDTokenRefresh, object: nil) 
    return true 
} 
    func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) 
    { 
     print(userInfo) 
} 
    func tokenRefreshNotification(_ notification: UIViewController) 
    { 
     if let refreshedToken = InstanceID.instanceID().token() 
     { 
      print("InstanceID token: \(refreshedToken)") 
      UserDefaults.standard.set(refreshedToken, forKey: "Device_token") 
      UserDefaults.standard.synchronize() 
     } 
     // Connect to FCM since connection may have failed when attempted before having a token. 
     connectToFcm() 
    } 

    // [START connect_to_fcm] 
    func connectToFcm() 
    { 
     Messaging.messaging().shouldEstablishDirectChannel = true 
    } 

    func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) 
    { 

     //Tricky line 
     Messaging.messaging().apnsToken = deviceToken 
     //InstanceID.instanceID().setAPNSToken(deviceToken, type: InstanceIDAPNSTokenType.unknown) 
     print("Device Token:", tokenString) 
    } 

    func applicationDidBecomeActive(_ application: UIApplication) { 
     print("applicationDidBecomeActive ") 

     connectToFcm() 
    }

您沒有添加委託方法IOS 10，並檢查您的有效載荷有mutable-content = true：
