ios - 如何使用 firebase 获取设备 token ？

Question

在旧项目中，我在第一次安装应用程序或刷新 token 时收到了设备 token 。但是现在我创建了一个新项目并编写了用于注册设备 token 委托(delegate)并请求许可的代码，但是现在在 swift 版本 4.2 中没有调用注册设备 token 。有人遇到过这个问题吗？如果是，解决方案是什么？

    }

Answer 1

您也需要这样做以获得 firebase token

1. 在您的 AppDelegate 类中声明一个变量。

   var firebaseToken: String = "" 
   

2. 在您的 didFinishLaunchingWithOptions 函数中调用这些方法

   func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
   
       FirebaseApp.configure()
       self.registerForFirebaseNotification(application: application)
       Messaging.messaging().delegate = self
       return true
   }
   

3. 在您的 AppDelegate 类中添加此函数。

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

4. 最后创建 AppDelegate 的扩展并添加这些功能

   extension AppDelegate: MessagingDelegate, UNUserNotificationCenterDelegate {
   
   //MessagingDelegate
   func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
       self.firebaseToken = fcmToken
       print("Firebase token: \(fcmToken)")
   }
   
   func messaging(_ messaging: Messaging, didReceive remoteMessage: MessagingRemoteMessage) {
       print("didReceive remoteMessage: \(remoteMessage)")
   }
   
   //UNUserNotificationCenterDelegate
   func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
       print("APNs received with: \(userInfo)")
   
   
    }
   }
