FCM推送通知不适用于iOS 11

我使用Firebase作为后端。 我也使用FCM作为Firebase提供的function之一。 FCM在iOS 10中运行良好，但在切换到iOS 11之后，推送通知停止发送到用户设备，而我自己也没有收到Firebase控制台中的云function或通知部分发送的任何推送通知。 如何解决这个问题？

更新：我从Firebase Notifcations发送了几个推送通知，但他们没有来。

// MARK: - Push notification extension AppDelegate: UNUserNotificationCenterDelegate { func registerPushNotification(_ application: UIApplication) { // 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 }) // For iOS 10 data message (sent via FCM) Messaging.messaging().delegate = self } func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) { //When the notifications of this code worked well, there was not yet. Messaging.messaging().apnsToken = deviceToken } // [START receive_message] func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) { // If you are receiving a notification message while your app is in the background, // this callback will not be fired till the user taps on the notification launching the application. // TODO: Handle data of notification // Print message ID. if let messageID = userInfo[gcmMessageIDKey] { debugPrint("Message ID: \(messageID)") } // Print full message. debugPrint(userInfo) } func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) { // If you are receiving a notification message while your app is in the background, // this callback will not be fired till the user taps on the notification launching the application. // TODO: Handle data of notification // Print message ID. if let messageID = userInfo[gcmMessageIDKey] { print("Message ID: \(messageID)") } // Print full message. debugPrint(userInfo) completionHandler(.newData) } // showing push notification func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) { if let userInfo = response.notification.request.content.userInfo as?

String { if categoryID == RouterManager.Categories.newMessage.id { if let currentConversation = ChatGeneralManager.shared.currentChatPersonalConversation, let dataID = userInfo["dataID"] as? String { // dataID is conversationd id for newMessage if currentConversation.id == dataID { completionHandler([]) return } } } } if let badge = notification.request.content.badge { AppBadgesManager.shared.pushNotificationHandler(userInfo, pushNotificationBadgeNumber: badge.intValue) } } completionHandler([.alert,.sound, .badge]) } } // [START ios_10_data_message_handling] extension AppDelegate : MessagingDelegate { func messaging(_ messaging: Messaging, didRefreshRegistrationToken fcmToken: String) { let pushNotificationManager = PushNotificationManager() pushNotificationManager.saveNotificationTokenInDatabase(token: fcmToken, success: nil, fail: nil) } // Receive data message on iOS 10 devices while app is in the foreground. func application(received remoteMessage: MessagingRemoteMessage) { debugPrint(remoteMessage.appData) } }

看起来FirebaseInstanceID 2.0.3推送通知不起作用。 它帮助我设置：“FirebaseInstanceID”，“2.0.0”。 也许在下一个版本中这将被修复。

Answer 2

请更新您的FCM吊舱

 pod 'Firebase/Messaging' 

到最新版本，这是2.0.6

 Installing FirebaseInstanceID (2.0.6) Installing FirebaseMessaging (2.0.6) 

它应该与iOS 11+设备一起使用。

我读了这个主题，并添加了这个代码application.registerForRemoteNotifications()到AppDelegate方法didFinishLaunchingWithOptions ，它的工作，但不幸的是，当前用户将不会收到通知，直到他们更新到新版本。 请参阅https://github.com/firebase/quickstart-ios/issues/327#issuecomment-331782299
