你好，在我的应用程序中使用FCM。
当我试图读取FCM令牌时，即使编译器不调用此委托方法，也是任何方式，请帮助。
当我把休息和检查这个方法是不调用我使用ios11 swift4

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)
    }  
}

didReceiveRegistrationToken

是一个委托函数。它将在从Firebase接收令牌时被调用。如果它没有被调用，请确保在AppDelegate中有以下代码

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

使用Messaging.messaging().delegate = self，我们注册AppDelegate以接收来自Firebase的方法调用

我使用下面的功能，它工作正常

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        if let refreshedToken = InstanceID.instanceID().token() {
           print("InstanceID token: \(refreshedToken)")
        }
    }

如果之前的token被更新，则调用“didReceiveRegistrationToken”，否则每次调用“didRegisterForRemoteNotificationsWithDeviceToken”，直到token更新。
