FCM 推送通知在 iOS 11 上不起作用

问题描述

我使用 Firebase 作为后端.我还使用 FCM 作为 Firebase 提供的功能之一.FCM 在 iOS 10 中运行良好，但在切换到 iOS 11 后，推送通知停止发送到用户设备，我自己也没有收到从云功能或 Firebase 控制台中的通知部分发送的任何推送通知.如何解决这个问题?

I use Firebase as a backend. I also use FCM as one of the provided features from Firebase. FCM worked well in iOS 10, but after switching to iOS 11, push notifications stopped coming to user devices, and I myself did not receive any push notifications sent from the cloud functions or the Notification section in the Firebase Console. How to fix this problem?

更新:我从 Firebase 通知发送了几条推送通知，但没有收到.

Update: I sent several push notifications from Firebase Notifcations, but they do not come.

// 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 : Any] {
            let routerManager = RouterManager()
            routerManager.launchRouting(userInfo)
        }
        completionHandler()
    }

    func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
        if let userInfo = notification.request.content.userInfo as? [String : Any] {
            if let categoryID = userInfo["categoryID"] 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)
    }

}

推荐答案

FirebaseInstanceID 2.0.3 的推送通知似乎不起作用.它帮助我设置:pod 'FirebaseInstanceID', "2.0.0".也许下个版本会解决这个问题.

It appears that with FirebaseInstanceID 2.0.3 push notifications don't work. It helped me to set: pod 'FirebaseInstanceID', "2.0.0". Maybe in next version this will be fixed.
