Clear notifications badge without removing notifications

Question

In my app, I\'m receiving push notifications with badge number set to one. When app will start, it should set badges count to 0, so I\'m using:

[[UIApplicat         


        

Answer 1

With iOS9 directly setting badge to negative still clears notifications. You must fire empty UILocalNotification with negative badgenumber to achieve this.

let ln = UILocalNotification()
ln.applicationIconBadgeNumber = -1
UIApplication.sharedApplication().presentLocalNotificationNow(ln)

Answer 2

@feb for ios 9+ you need to set 0 not -1 for that you need to add version condition

    if #available(iOS 9.0, *) {
        UIApplication.shared.applicationIconBadgeNumber = 0
    }else{
        UIApplication.sharedApplication().applicationIconBadgeNumber = -1
    }

According to this topic:

How to clear badge number while preserving notification center

setting:

[[UIApplication sharedApplication] setApplicationIconBadgeNumber:-1];

should do the trick.
