How to remove the cancel ApplicationIconBadgeNumber from LocalNotification?

问题

I am using LocalNotification in my app. It is working fine but once ApplicationIconBadgeNumber is set, not able to remove it from App. How to remove it?

回答1:

You need to set the application applicationIconBadgeNumber. For example in the application didReceiveLocalNotification.

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notif {
    application.applicationIconBadgeNumber = notif.applicationIconBadgeNumber-1;
}
