Yes. But i want to reset it when user clears tray.Is it possible? – Zymogenic

no you can not set icon badge number without opening application. – Thermos

actually you can. but you need to used push notification [developer.apple.com/library/content/documentation/… – Cruet

Answer 1

What you want to achieve is only possible using the Server Notifications. You can not set badge number locally without opening the application. As you won't have any control when user clears the tray. There's no way you can set the badge count at that moment.

Is it possible to get that tray has any notification when app launches? – Zymogenic

@Impossible no there's no way. You have no control at that moment. – Jerad

Answer 3

For Swift3, you can clear badge number in your application didFinishLaunchingWithOptions with this line :

UIApplication.shared.applicationIconBadgeNumber = 0

You can used this line in anywhere in code if you want too.

I am having the problem that even if I delete the badge number with the above code, if a new message coming the badge number is not starting from 1, but having x+1 where x was the previous number of messages. What can be the issue here? – Amery
