Updating iOS badge without push notifications
Try this
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:1];To do this through local notifications you have to set the value in applicationIconBadgeNumber
UILocalNotification *localNotification = [[UILocalNotification alloc] init];localNotification.applicationIconBadgeNumber = 1;// set here the value of badge
And for everyone using new and shiny Swift:
UIApplication.sharedApplication().applicationIconBadgeNumber = someNumberSwift 3:
UIApplication.shared.applicationIconBadgeNumber = someNumber
Since iOS 4.0 you can fire local notifications on all devices that run at least iOS 4.0. Look into the UILocalNotification class, it allows you to set the badge at midnight without having your app running.
