Ios 当我断开设备与Xcode的连接时，推送通知不起作用

我正在使用swift语言开发一个IOS应用程序。我已将基于Firebase的推送通知添加到我的项目中。当我的设备连接到xcode或在我的设备上调试我的应用程序时，它们可以正常工作。但当我从xcode上断开设备连接，或者在没有调试推送通知的情况下使用应用程序时，推送通知都不起作用。我正在寻找解决办法

应用程序代理文件中的我的代码

在didFinishLaunchingWithOptions函数中

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: { (bool, err) in

        })

    } else {

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

    }

    application.registerForRemoteNotifications()
    UIApplication.shared.applicationIconBadgeNumber = 0

在didregisterdevicewithtoken函数中

 func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    print("APNs token retrieved: \(deviceToken)")

    // With swizzling disabled you must set the APNs token here.
    if let refreshedToken = InstanceID.instanceID().token() {
        print("InstanceID token: \(refreshedToken)")

    }
    let tokenT = deviceToken.map { String(format: "%02.2hhx", $0) }.joined()
    print(tokenT)
    guard let token = InstanceID.instanceID().token() else {return}
    AppDelegate.DEVICEID = token
    print(token)
    UserDefaults.standard.set(token, forKey: "token")

    connectToFCM()


}

以及生成通知

 func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],
                 fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
    // If you are receiving a notification message while your app is in the background,
    // this callback will not be fired till the user taps on the notification launching the application.
    // TODO: Handle data of notification

    // With swizzling disabled you must let Messaging know about the message, for Analytics
    // Messaging.messaging().appDidReceiveMessage(userInfo)

    // Print message ID.
    if let messageID = userInfo[gcmMessageIDKey] {
        print("Message ID: \(messageID)")
    }

    if let msg = userInfo["desc"] as? String
    {
        let title = userInfo["noti_title"] as? String
        createNotification(message: msg, title: title ?? "" )

    }

    // Print full message.
    print(userInfo)

    completionHandler(UIBackgroundFetchResult.newData)
}


func createNotification(message: String, title: String) {

    let content = UNMutableNotificationContent()
    content.title =  title
    content.body = message


    let triger = UNTimeIntervalNotificationTrigger(timeInterval: 2, repeats: false )
    let request = UNNotificationRequest(identifier: "TextMessage", content: content, trigger: triger)



    UNUserNotificationCenter.current().add(request, withCompletionHandler: nil)
}

UNUserNotificationCenterDelegate

extension AppDelegate : UNUserNotificationCenterDelegate {

// Receive displayed notifications for iOS 10 devices.
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification,                            withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {

    let userInfo = notification.request.content.userInfo

    if let messageID = userInfo[gcmMessageIDKey] {
        print("Message ID: \(messageID)")
    }

    print(userInfo)

    // Change this to your preferred presentation option
    completionHandler([.alert,.badge,.sound])
}


func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
    let application = UIApplication.shared

    if(application.applicationState == .active){
        print("user tapped the notification bar when the app is in foreground")

        window = UIWindow(frame: UIScreen.main.bounds)
        window?.makeKeyAndVisible()

        //        let layout = UICollectionViewFlowLayout()
        window?.rootViewController = UINavigationController(rootViewController: NotificationViewController())


    }

    if(application.applicationState == .inactive)
    {
        print("user tapped the notification bar when the app is in background")
        window = UIWindow(frame: UIScreen.main.bounds)
        window?.makeKeyAndVisible()

        //        let layout = UICollectionViewFlowLayout()
        window?.rootViewController = UINavigationController(rootViewController: NotificationViewController())

    }

    /* Change root view controller to a specific viewcontroller */
    // let storyboard = UIStoryboard(name: "Main", bundle: nil)
    // let vc = storyboard.instantiateViewController(withIdentifier: "ViewControllerStoryboardID") as? ViewController
    // self.window?.rootViewController = vc

    completionHandler()
}

func connectToFCM()
{
    Messaging.messaging().shouldEstablishDirectChannel = true
}
func initializeNotificationServices() -> Void {
    let settings = UIUserNotificationSettings(types: [.sound, .alert, .badge], categories: nil)
    UIApplication.shared.registerUserNotificationSettings(settings)

    // This is an asynchronous method to retrieve a Device Token
    // Callbacks are in AppDelegate.swift
    // Success = didRegisterForRemoteNotificationsWithDeviceToken
    // Fail = didFailToRegisterForRemoteNotificationsWithError
    UIApplication.shared.registerForRemoteNotifications()

我已经解决了这个问题。现在，我在firebase控制台中添加了生产Apn证书，并从firebase控制台中删除了开发Apn证书。对于有相同问题的用户，请从apple.developers生成您的生产apn，并在build选项卡中将您的项目方案从debug更改为release。

显示一些代码以更好地理解您的问题。您尚未实现UnuseNotificationCenterDelegate方法，因此不会收到推送通知。有关完整信息，请参阅此博客。抱歉，我忘了向您显示我已再次更新了问题。请选中“将该代码添加到问题中”。您是否已将该代码放入FIRApp.configure（）中？？如果是这样，那么你的代码就完全正确了。那么问题就出在别的地方了。
