【问题描述】：

我使用 Firebase 云消息。我有 pod ‘FirebaseInstanceID’, ‘= 1.0.2’，然后我将它更新为 = 2.0.4。现在我得到了 InstanceID.instanceID().token() 和 APN。

更新我的 FirebaseInstanceID 版本后，我的通知不再起作用，我不明白为什么。

我还添加了“GoogleService-Info.plist”。

我的豆荚 pod 'Firebase/Core' pod ‘FirebaseInstanceID’, ‘= 2.0.4’ pod 'Firebase/Messaging' 我的 AppDelegate：

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool 
    // Use Firebase library to configure APIs
        FirebaseConfiguration.shared.setLoggerLevel(.min)
        FirebaseApp.configure()

    Messaging.messaging().remoteMessageDelegate = self
    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()


//Notifiction
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) 
    if let messageID = userInfo[gcmMessageIDKey] 
        print("Message ID: \(messageID)")
    

    openScreenFromPush(userInfo: userInfo)
    print(userInfo)


func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],
                 fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) 

    if let messageID = userInfo[gcmMessageIDKey] 
        print("Message ID: \(messageID)")
    

    openScreenFromPush(userInfo: userInfo)

    print(userInfo)
    completionHandler(UIBackgroundFetchResult.newData)


// [END receive_message]
func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) 
    print("Unable to register for remote notifications: \(error.localizedDescription)")


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

    var token = ""
    for i in 0..<deviceToken.count 
        token = token + String(format: "%02.2hhx", arguments: [deviceToken[i]])
    
    print("APNs token retrieved: \(token)")


// [START ios_10_message_handling]
@available(iOS 10, *)

extension AppDelegate : UNUserNotificationCenterDelegate 

    // Receive displayed notifications for iOS 10 devices.
    func userNotificationCenter(_ center: UNUserNotificationCenter,
                                willPresent notification: UNNotification,
                                withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) 
        let userInfo = notification.request.content.userInfo

        if let messageID = userInfo[gcmMessageIDKey] 
            print("Message ID: \(messageID)")
        

        print(userInfo)

        // Change this to your preferred presentation option
        completionHandler([.alert, .badge, .sound])
    

    func userNotificationCenter(_ center: UNUserNotificationCenter,
                                didReceive response: UNNotificationResponse,
                                withCompletionHandler completionHandler: @escaping () -> Void) 
        let userInfo = response.notification.request.content.userInfo
        // Print message ID.
        if let messageID = userInfo[gcmMessageIDKey] 
            print("Message ID: \(messageID)")
        

        openScreenFromPush(userInfo: userInfo)

        // Print full message.
        print(userInfo)

        completionHandler()
    

// [END ios_10_message_handling]
extension AppDelegate : MessagingDelegate 
    // [START refresh_token]
    func messaging(_ messaging: Messaging, didRefreshRegistrationToken fcmToken: String) 
        print("Firebase registration token: \(fcmToken)")
    
    // [END refresh_token]
    // [START ios_10_data_message]
    func application(received remoteMessage: MessagingRemoteMessage) 
        print("Received data message: \(remoteMessage.appData)")
    
    // [END ios_10_data_message]

【参考方案1】：

由于某种原因，您必须将 UIApplication.shared.registerForRemoteNotifications() 放在 FirebaseApp.configure() 之前

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

        // Register for remote notifications. This shows a permission dialog on first run, to
        // show the dialog at a more appropriate time move this registration accordingly.
        // [START register_for_notifications]




        UIApplication.shared.registerForRemoteNotifications()

        FirebaseApp.configure()

        // [START set_messaging_delegate]
        Messaging.messaging().delegate = self
        // [END set_messaging_delegate]
        // Register for remote notifications. This shows a permission dialog on first run, to
        // show the dialog at a more appropriate time move this registration accordingly.
        // [START register_for_notifications]
        if #available(iOS 10.0, *) 
            let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
            UNUserNotificationCenter.current().requestAuthorization(
                options: authOptions,
                completionHandler: _, _ in )

            // For iOS 10 display notification (sent via APNS)
            UNUserNotificationCenter.current().delegate = self
            // For iOS 10 data message (sent via FCM)
            Messaging.messaging().remoteMessageDelegate = self

         else 
            let settings: UIUserNotificationSettings =
                UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
            application.registerUserNotificationSettings(settings)
        




        // [END register_for_notifications]
        return true
    

【参考方案2】：

我加InstanceID.instanceID().setAPNSToken(deviceToken, type: InstanceIDAPNSTokenType.unknown)

在：

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) 
    var token = ""
    for i in 0..<deviceToken.count 
        token = token + String(format: "%02.2hhx", arguments: [deviceToken[i]])
    

    print("APNs token retrieved: \(token)")

方法。它有效
