ios - 当我断开设备与 Xcode 的连接时，推送通知不起作用

Question

我正在使用 swift 语言开发 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 或当我在设备上调试我的应用程序时，它们可以正常工作。但是，当我从 xcode 断开设备连接或使用应用程序而不调试时，推送通知不起作用。我正在寻找解决方案

我在应用程序委托(delegate)文件中的代码

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()


}

并生成通知

 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()

这个问题我已经解决了。现在我已在 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。对于那些遇到同样问题的人，请从 apple.developers 生成您的生产 apn，并在构建选项卡中将您的项目方案从调试更改为发布。
