推送通知不起作用

Question

我使用Firebase云消息。我有pod'FirebaseInstanceID'，'= 1.0.2'，然后我将其更新为= 2.0.4。现在我收到了InstanceID.instanceID（）。token（）和APN。

在我更新了我的FirebaseInstanceID版本后，我的通知不再有效，我不明白为什么。

我还添加了'GoogleService-Info.plist'。

出于某种原因，您必须将UIApplication.shared.registerForRemoteNotifications()放在FirebaseApp.configure（）

之前

   func application(_ application: UIApplication,
                     didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

        // Register for remote notifications. This shows a permission dialog on first run, to
        // show the dialog at a more appropriate time move this registration accordingly.
        // [START register_for_notifications]




        UIApplication.shared.registerForRemoteNotifications()

        FirebaseApp.configure()

        // [START set_messaging_delegate]
        Messaging.messaging().delegate = self
        // [END set_messaging_delegate]
        // Register for remote notifications. This shows a permission dialog on first run, to
        // show the dialog at a more appropriate time move this registration accordingly.
        // [START register_for_notifications]
        if #available(iOS 10.0, *) {
            let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
            UNUserNotificationCenter.current().requestAuthorization(
                options: authOptions,
                completionHandler: {_, _ in })

            // For iOS 10 display notification (sent via APNS)
            UNUserNotificationCenter.current().delegate = self
            // For iOS 10 data message (sent via FCM)
            Messaging.messaging().remoteMessageDelegate = self

        } else {
            let settings: UIUserNotificationSettings =
                UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
            application.registerUserNotificationSettings(settings)
        }




        // [END register_for_notifications]
        return true
    }

Answer 2

我添加InstanceID.instanceID().setAPNSToken(deviceToken, type: InstanceIDAPNSTokenType.unknown)

in：

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    var token = ""
    for i in 0..<deviceToken.count {
        token = token + String(format: "%02.2hhx", arguments: [deviceToken[i]])
    }

    print("APNs token retrieved: \(token)")
}

方法。它的工作原理
