当Ios应用程序已在后台运行时，我可以点击消息并进入应用程序并查看通知视图

但应用程序被杀了我无法进入应用程序并查看自定义通知视图这是我用来加载自定义通知视图控制器

的覆盖方法

    func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],
                 fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {

    let json = JSON(userInfo)

    var title = ""
    var content = ""
    NSLog("Received a Notificat`ion: \(json)")
    if let messageID = json["aps"]["alert"]["title"].string{
        print("Message ID: \(messageID)")
        title = messageID
    }

    if let body = json["aps"]["alert"]["body"].string{
        print("Message ID: \(body)")
        content = body
    }
    print(json["message"].string)
    let payloadObj = convertStringToDictionary(text: json["message"].string ?? "")
    print(payloadObj)



    var CustomerName = ""
    var CustomerContactNo =  ""

    if let type = payloadObj?["Type"]{
        let    _notificationType = type as? String

        if(_notificationType == "ORDERSTATUS"){
            name = (payloadObj?["Name"]as? String)!

            CustomerName = (payloadObj?["CustomerName"]as? String)!
            CustomerContactNo = (payloadObj?["CustomerContactNo"]as? String)!


            let storyboard = UIStoryboard.init(name: "Main", bundle: nil)
            let viewController = storyboard.instantiateViewController(withIdentifier: "NotificationViewController") as! NotificationViewController

            viewController.Name = CustomerName

            viewController.contact = CustomerContactNo

            if let navigationController = self.window?.rootViewController as? UINavigationController
            {
                navigationController.pushViewController(viewController, animated: true)
            }

        }

        completionHandler(UIBackgroundFetchResult.newData)

    }

}

试试这个代码。设置你的 AppDelegate 文件代码......

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

    self.registerForPushNotifications()

    return true
}

func registerForPushNotifications() {
    UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge]) {
        (granted, error) in
        print("Permission granted: \(granted)")

        guard granted else { return }
        self.getNotificationSettings()
    }
}

func getNotificationSettings() {
    UNUserNotificationCenter.current().getNotificationSettings { (settings) in
        print("Notification settings: \(settings)")
        guard settings.authorizationStatus == .authorized else { return }
        DispatchQueue.main.async {
            UIApplication.shared.registerForRemoteNotifications()
        }
    }
}

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

    let userInfo = response.notification.request.content.userInfo
    let aps = userInfo["aps"] as! [String: AnyObject]
    let dic = aps as NSDictionary
    //here set your push any viewcontroller logic 
    completionHandler()
}

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any],fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {

    let aps = userInfo["aps"] as! [String: AnyObject]
    let dic = aps as NSDictionary
    //here set your push any viewcontroller logic 
    completionHandler(.newData)
}
