云消息传递-本地化推送通知

Question

我尝试通过iOS上的Firebase Cloud-Messaging本地化推送通知。

我需要修改此代码多远才能使其起作用？我看不到任何适合放置NSLocalizedString的地方...

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


    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()
    Messaging.messaging().delegate = self

    return true
}

@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)
        completionHandler([.alert])
      }

 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)")
}

// Print full message.
print(userInfo)

completionHandler()
}
}

extension AppDelegate: MessagingDelegate {
func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
  print("Firebase registration token: \(fcmToken)")

  let dataDict:[String: String] = ["token": fcmToken]
  NotificationCenter.default.post(name: Notification.Name("FCMToken"), object: nil, userInfo: dataDict)
  // TODO: If necessary send token to application server.
  // Note: This callback is fired at each app startup and whenever a new token is generated.
}

func messaging(_ messaging: Messaging, didReceive remoteMessage: MessagingRemoteMessage) {
    print("Message Data", remoteMessage.appData)
}

}

如您所见，所有代码都来自我的AppDelegate类...有什么方法可以解决此问题？我知道本地通知的本地化，但遗憾的是远程通知的本地化。
