Question

在旧项目中，第一次安装应用程序或刷新令牌时，我已收到设备令牌。但是，现在我创建了一个新项目，并为注册设备令牌委托和请求权限编写了代码，但现在在4.2版本中未调用注册设备令牌。有人遇到过这个问题吗？如果是，解决方案是什么？

Answer 1

您也需要获取Firebase令牌

在AppDelegate类中声明一个变量。
```
var firebaseToken: String = "" 
```

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
}

在您的AppDelegate类中添加此功能。

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()
}
}

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)")


 }
}

Answer 2

您必须调用以下函数来获取fcm令牌，

func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
  print("Firebase registration token: \(fcmToken)")
  UserDefaults.standard.set(fcmToken, forKey: "DeviceToken")
}

，然后将您的didFinishLaunchingWithOptions()的appDelegate编辑为，

 func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    FirebaseApp.configure()
    if(launchOptions?[UIApplication.LaunchOptionsKey.remoteNotification] != nil){

    }
    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)")

        }
    }

    Messaging.messaging().isAutoInitEnabled = true
    if #available(iOS 10.0, *) {
        // For iOS 10 display notification (sent via APNS)
        UNUserNotificationCenter.current().delegate = self

        let authOptions: UNAuthorizationOptions = [.alert,.sound] //  .badge,
        UNUserNotificationCenter.current().requestAuthorization(
            options: authOptions,
            completionHandler: {_, _ in })
    } else {
        let settings: UIUserNotificationSettings =
            UIUserNotificationSettings(types: [.alert,.sound], categories: nil)
        application.registerUserNotificationSettings(settings)
    }

    application.registerForRemoteNotifications()

   Messaging.messaging().delegate = self


    return true
}

swift中的相同方法将帮助您跟踪令牌委托数据

- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error {


    NSLog(@"Unable to register for remote notifications: %@", error);

}

// 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 device token can be paired to
// the FCM registration token.
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {


    NSLog(@"APNs device token retrieved: %@", deviceToken);
    // With swizzling disabled you must set the APNs device token here.

     [FIRMessaging messaging].APNSToken = deviceToken;
}
