ios - FCM token 不调用 didReceiveRegistrationToken

Question

您好，在我的应用程序中使用 FCM。

当我尝试读取 FCM token 时，即使编译器不调用此委托(delegate)方法，也请提供帮助。

当我放置中断并检查此方法时，不要使用 ios11 swift4 调用我

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(delegate)函数。它将在收到 Firebase 的 token 后被调用。如果没有被调用，请确保您已遵循 AppDelegate 中的代码

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

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