Question

我想在iOS中实现推送通知。我成功地使它工作了一次。但现在我面临一个奇怪的问题。我已经退出XCode并重新打开它，没有代码被更改，我仍然得到deviceToken，但现在我没有在我的设备上收到任何推送通知。我也使用Firebase来获取通知，它也工作正常，但现在它给我空白字符串作为设备令牌。

在AppDelegate中我使用以下代码：

    if #available(iOS 10.0, *) {
        // For iOS 10 display notification (sent via APNS)
        UNUserNotificationCenter.current().delegate = self

        let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
        UNUserNotificationCenter.current().requestAuthorization(
            options: authOptions,
            completionHandler: {_, _ in })
    } else {
        let settings: UIUserNotificationSettings =
            UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
        application.registerUserNotificationSettings(settings)
    }

    application.registerForRemoteNotifications()

//This is triggered and I am getting the push notification token but using this instead of firebase token to send directly via APNS is also not working.
public func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    Messaging.messaging().setAPNSToken(deviceToken, type: .sandbox)
}

//This is triggered but the token here is a blank string
func messaging(_ messaging: Messaging, didRefreshRegistrationToken fcmToken: String) {
    Messaging.messaging().subscribe(toTopic: "ios_topic")
}

直到我退出XCode才开始工作，但突然间它在没有任何代码更改的情况下停止工作。我尝试了一切，包括系统重启。有时didRegisterForRemoteNotificationsWithDeviceToken在全新安装期间被调用两次，一次是在我授予权限之前，一次是在授予权限之后。

也许是因为设备令牌现在被解析为'32BYTES'。

Swift 3 - device tokens are now being parsed as '32BYTES'

调用didRegisterForRemoteNotificationsWithDeviceToken但未发送推送通知
