I have an App in which i am facing the issue that the badge number only gets updated when i open the notification but i need to update the badge number even when app is not open.
Can anyone help me with that??
You need to set a value for the badge
key in your push notification payload. From your description, it sounds like it is only your application which is updating the badge number, and not the notification itself.
See The Notification Payload of the Local and Push Notification Programming Guide for details:
Keys and values of the aps dictionary
badge
(number): The number to display as the badge of the application icon. If this property is absent, the badge is not changed. To remove the badge, set the value of this property to 0.
