Clearing the badge when received Push Notification

Question

How can I clear the badge which appears on application icon when I receive Push Notification? I want to clear it once user has either tapped on "View" of Push notification alert or has tapped on the app icon.

Answer 1

I suspect you are talking about the SpringBoard's badge:

[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0]

Answer 2

Badge count set Zero

[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0]

Cancel all local notifications with this code:

[[UIApplication sharedApplication] cancelAllLocalNotifications];

Cancel one local notification with this line of code:

[[UIApplication sharedApplication] cancelLocalNotification:theNotification];

here theNotification is a UILocalNotification object, so in order to cancel a specific notification, you need to hold on to it's UILocalNotification.

Check this.
