Clear applicationIconBadgeNumber without removing notifications not working
I've read in a few posts (like this one https://forums.developer.apple.com/thread/7598) that setting
application.applicationIconBadgeNumber = -1
on applicationDidBecomeActive or applicationWillEnterForeground would allow me to clear the badge number without removing the notifications from the notification center. When I set application.applicationIconBadgeNumber to a negative number (like -1) it clears all my notifications from the Notification Center . Is there another way to clear the badge number without removing the notifications ?
Setting application badge to -1 indirectly with a empty local notification worked for me, but its a hack to persist notifications in tray while clearing application badge count.
if(badgeCount == 0) {
//set application badge indirectly with UILocalNotification
UILocalNotification *ln = [[UILocalNotification alloc]init];
ln.applicationIconBadgeNumber = -1;
[[UIApplication sharedApplication] presentLocalNotificationNow:ln];
}
else {
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:badgeCount];
}
Swift Version
if badgeCount == 0 {
//set application badge indirectly with UILocalNotification
var ln = UILocalNotification()
ln.applicationIconBadgeNumber = -1
UIApplication.sharedApplication().presentLocalNotificationNow(ln)
}
else {
UIApplication.sharedApplication().applicationIconBadgeNumber = badgeCount
}
Approach tested on iOS 9 and 10.
