title: Apple push notification badge number
body: <p>I have developed server side application to maintain the badge number as increment or decrement after receiving new notification and delete after seeing notification it works fine.</p>
  
  <p>But there is some problem in showing the badge, the actual scenario is - After getting new notification on device, I am click on cancel button then badge number shows correctly but after that I will open the application and close the application badge will be removed. That means I am not sending request to the server that notification was seen by me and now you can decrement the badge by one. Then also badge removed from app icon. </p>
  
  <p>My question is that when we open the application then badge number automatically removed from (application) device? or it will shows as it is until we set to zero?</p>
