無法將通知發送到iOS（iPhone）Firebase雲消息傳遞

Question

在Info.plist ，我將FirebaseAppDelegateProxyEnabled添加到NO (boolean) ，並且Background Modes --> Remote Notification功能Background Modes --> Remote Notification處於啟用狀態，而Push Notification也處於啟用狀態。

並在iPhone設備上運行了帶有“允許通知”對話框。

我有一些代碼，例如：

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
    var window: UIWindow?

    let gcmBroadcast = "gcm.broadcast"

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


        Messaging.messaging().delegate = self

        // Use Firebase library to configure APIs

        let firebasePListFileName = ControllerEnvironment.getGoogleService()

        let firebaseOptions = FirebaseOptions(contentsOfFile: Bundle.main.path(forResource: firebasePListFileName, ofType: "plist")!)

        FirebaseApp.configure(options: firebaseOptions!)



//        firebase cloud messaging

        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()

        return true

    }



    // [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

        // With swizzling disabled you must let Messaging know about the message, for Analytics

         Messaging.messaging().appDidReceiveMessage(userInfo)

        // Print message ID.

        if let messageID = userInfo[gcmBroadcast] {

            print("Message ID: \(messageID)")

        }

        // Print full message.
        print(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

        // With swizzling disabled you must let Messaging know about the message, for Analytics

         Messaging.messaging().appDidReceiveMessage(userInfo)

        // Print message ID.

        if let messageID = userInfo[gcmBroadcast] {

            print("Message ID: \(messageID)")

        }

        // Print full message.
        print(userInfo)

        completionHandler(UIBackgroundFetchResult.newData)

    }

    // [END receive_message]

    func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {

        print("Unable to register for remote notifications: \(error.localizedDescription)")

    }


    // This function is added here only for debugging purposes, and can be removed if swizzling is enabled.

    // If swizzling is disabled then this function must be implemented so that the APNs token can be paired to

    // the FCM registration token.

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

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

        // With swizzling disabled you must set the APNs token here.

         Messaging.messaging().apnsToken = deviceToken

    }

}

和日志：

Firebase registration token: f6MUKT270iw:APA9.......Eg
APNs token retrieved: 32 bytes

我嘗試使用Firebase雲消息傳遞控制台將Push發送為： User segment -> app並在消息的Firebase列表中完成了狀態。

但是，實際上我的iPhone沒有收到通知。

我該如何解決這個問題？

Answer 1

在iOS上，該應用程序不必位於前台，否則開發人員會收到推送通知的通知，並可以手動顯示/處理該通知->確保該應用程序不在前台

您還需要向Firebase添加APNs密鑰或APNs證書。
