Swift 5 iOS12 - 推送通知不起作用

Question

我使用 Firebase 发送了通知，但通知未发送至手机。我认为代码有问题。你能检查一下问题出在哪里吗？我正在通过 Firebase 发送云消息，但它不起作用，没有收到任何通知。我的应用程序安装在苹果商店中。我正确加载了证书。

extension AppDelegate: UNUserNotificationCenterDelegate {

    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {

        completionHandler()
    }

    func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {

    }

    func application(_ application: UIApplication,
                     didReceiveRemoteNotification notification: [AnyHashable : Any],
                     fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
        if Auth.auth().canHandleNotification(notification) {
            completionHandler(UIBackgroundFetchResult.noData)
            return
        }
        // This notification is not auth related, developer should handle it.
    }


    func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        // Pass device token to auth
        Auth.auth().setAPNSToken(deviceToken, type: AuthAPNSTokenType.sandbox)

        // Further handling of the device token if needed by the app
        // ...
    }

    func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {

    }

    /// Register for push notifications
    func registerForPushNotification(){

        if #available(iOS 10.0, *) {
            let center  = UNUserNotificationCenter.current()
            center.delegate = self
            center.requestAuthorization(options: [.sound, .alert, .badge]) { (granted, error) in
                if error == nil{
                    DispatchQueue.main.async {
                        UIApplication.shared.registerForRemoteNotifications()
                    }
                }
            }
        } else {

            let settings = UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
            UIApplication.shared.registerUserNotificationSettings(settings)
            UIApplication.shared.registerForRemoteNotifications()
        }
    }
}


extension AppDelegate: MessagingDelegate {

    func application(received remoteMessage: MessagingRemoteMessage) {


    }

    func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {

        print(fcmToken)

    }
}
class AppDelegate: UIResponder, UIApplicationDelegate, UITabBarControllerDelegate {
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        //UIApplication.shared.isIdleTimerDisabled = true
        UIApplication.shared.setMinimumBackgroundFetchInterval(1800)

        Messaging.messaging().delegate = self
        FirebaseApp.configure()
        Fabric.sharedSDK().debug = true
        Fabric.with([Crashlytics.self()])

        self.registerForPushNotification()
}
    func application(_ application : UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool
    {
        if FUIAuth.defaultAuthUI()?.handleOpen(url, sourceApplication: sourceApplication) ?? false {
            return true
        }
        // other URL handling goes here.
        return false

    }

我会关注this tutorial用于通过 Firebase Cloud Messaging 发送和接收推送通知。设备可能需要服务器 key 和 token 来发送/接收本教程向您展示如何提供的通知。请确保不要将服务器 key 直接硬编码到您的代码中。您应该将其放入全局常量文件之类的文件中并从那里获取它。
