Почему pu sh уведомление ios работает после перезагрузки устройства?

0 голосов
/ 25 апреля 2020

Я пытаюсь реализовать уведомление pu sh через FCM (Firebase Cloud Messaging). Прямо сейчас я использую Messaging.messaging().subscribe для фонового уведомления pu sh. Но почему-то одна минута уведомление pu sh работает и через некоторое время оно не работает полностью. Затем, когда я перезагружаю устройство, уведомление pu sh снова начинает работать. В чем проблема ??

Это базовая c настройка в AppDelegate 

import UIKit
import UserNotifications
import Firebase

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

  let gcmMessageIDKey = "gcm.message_id"

  func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.
    FirebaseApp.configure()
    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)
    }
    Messaging.messaging().delegate = self
//    Messaging.messaging().unsubscribe(fromTopic: "dev_store_abcde-acbcd-adbcd-bcddd") { error in
//      print("unsub")
//    }
    application.registerForRemoteNotifications()
    return true
  }

  func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    let deviceTokenString = deviceToken.hexString
    print(deviceTokenString)
    InstanceID.instanceID().instanceID { (result, error) in
      if let error = error {
        print("Error fetching remote instance ID: \(error)")
      } else if let result = result {
        print("Remote instance ID token: \(result.token)")
      }
    }
  }
  // MARK: UISceneSession Lifecycle

  func application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> UISceneConfiguration {
    // Called when a new scene session is being created.
    // Use this method to select a configuration to create the new scene with.
    return UISceneConfiguration(name: "Default Configuration", sessionRole: connectingSceneSession.role)
  }

  func application(_ application: UIApplication, didDiscardSceneSessions sceneSessions: Set<UISceneSession>) {
    // Called when the user discards a scene session.
    // If any sessions were discarded while the application was not running, this will be called shortly after application:didFinishLaunchingWithOptions.
    // Use this method to release any resources that were specific to the discarded scenes, as they will not return.
  }

    Messaging.messaging().subscribe(toTopic: "dev_store_id") { error in
      print("Subscribe to dev_store_id")
    }
    // TODO: If necessary send token to application server.
    // Note: This callback is fired at each app startup and whenever a new token is generated.
  }
