        UIApplication.sharedApplication().registerUserNotificationSettings(settings)

        

        // This is an asynchronous method to retrieve a Device Token

        // Callbacks are in AppDelegate.swift

        // Success = didRegisterForRemoteNotificationsWithDeviceToken

        // Fail = didFailToRegisterForRemoteNotificationsWithError

        UIApplication.sharedApplication().registerForRemoteNotifications()

    }

    

    

    func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {

        let deviceTokenStr = convertDeviceTokenToString(deviceToken)

        // ...register device token with our Time Entry API server via REST

        print("dynamic Device Token:    \(deviceTokenStr)")
