Это мой код. Есть что-нибудь, что я должен добавить для localNotification. Какие-либо предложения. Заранее спасибо. Я прочитал много местных руководств по уведомлению. Я понятия не имею, что пропустили.

var localNotifications : UILocalNotification!

    func application(application: UIApplication!, didFinishLaunchingWithOptions launchOptions: NSDictionary!) -> Bool {

        localNotifications  = UILocalNotification()
        localNotifications.fireDate = NSDate(timeIntervalSinceNow: 20)
        localNotifications.timeZone = NSTimeZone.defaultTimeZone()
        localNotifications.alertBody = "Check it out!"
        localNotifications.soundName = UILocalNotificationDefaultSoundName
        localNotifications.applicationIconBadgeNumber = UIApplication.sharedApplication().applicationIconBadgeNumber + 1
        UIApplication.sharedApplication().scheduleLocalNotification(localNotifications)

}

 func application(application: UIApplication, didReceiveLocalNotification notification: UILocalNotification) {

        println("Alvin Notification recieved")

        if application.applicationState == UIApplicationState.Active
        {
            // show alertView

            Utilities.sharedInstance.alertThis("Hello", message: "Hey")
        }
        else if application.applicationState == UIApplicationState.Background
        {
            UIApplication.sharedApplication().presentLocalNotificationNow(localNotifications)
        }
        else if application.applicationState == UIApplicationState.Inactive
        {
            UIApplication.sharedApplication().presentLocalNotificationNow(localNotifications)
        }

        application.applicationIconBadgeNumber = 0
    }
