Question

嗨iam尝试实施google firebase推送通知并订阅主题。

我能够接收推送通知但不能订阅topic.Error说Cannot subscribe to topic: 000000005eb68872 with token: (null)但我已经生成了令牌。

我正在使用IOS 11和Xcode 9.0

Pod文件

target 'VQ Smart Home' do
  # Comment the next line if you're not using Swift and don't want to use dynamic frameworks
  use_frameworks!

  # Pods for VQ Smart Home
    pod 'SwiftyJSON'
    pod 'NVActivityIndicatorView'
    pod 'Firebase/Core', '4.0.4'
    pod 'Firebase/Database', '4.0.4'
    pod 'Firebase/Messaging', '4.0.4'
    pod 'FirebaseInstanceID', '2.0.0'
end

的AppDelegate

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

    UINavigationBar.appearance().isTranslucent = true



/************************ FireBase Notification ************************************************************************/
    FirebaseApp.configure()
    if #available(iOS 10.0, *) {
        UNUserNotificationCenter.current().delegate = self as? UNUserNotificationCenterDelegate
        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()

    let token = Messaging.messaging().fcmToken
     print("********* FCM token: \(token ?? "") *************")

    hubId = (isKeyPresentInUserDefaults(key: "hubID")) ?  (UserDefaults.standard.value(forKey: "hubID") as? String)! : "NohubId"
    Messaging.messaging().subscribe(toTopic: hubId)

/************************ FireBase Notification ************************************************************************/

    return true
}

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    Messaging.messaging().apnsToken = deviceToken
}

// Push Notification Methods
func messaging(_ messaging: Messaging, didRefreshRegistrationToken fcmToken: String) {
    print("Firebase registration token: \(fcmToken)")
}

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) {
    print(userInfo)
}

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],
                 fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
    print(userInfo)
    let aps = userInfo["aps"] as! NSDictionary
    print(aps["alert"]  as? String ?? "")
    completionHandler(UIBackgroundFetchResult.newData)
}

找到解决方案

我试图在 didFinishLaunchingWithOptions 中订阅主题，但在此期间未加载所有require方法和模块。所以我将订阅代码移到 didRegisterForRemoteNotificationsWithDeviceToken 中，现在它可以正常工作。

 func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        Messaging.messaging().apnsToken = deviceToken
        Messaging.messaging().subscribe(toTopic: hubId)
    }

FCM无法订阅主题：000000005eb68872 with token：（null）
