FCM 令牌不调用 didReceiveRegistrationToken

Question

您好，FCM在我的应用程序中使用。

当我尝试读取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。

当我休息并检查此方法时，请不要调用我使用 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。它会在收到来自 firebase 的令牌时被调用。如果它没有被调用，请确保您在 AppDelegate 中遵循了代码

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

与 Messaging.messaging().delegate = self我们正在注册AppDelegate用于接收从火力地堡方法调用
