iOS Question

Updating iOS badge without push notifications

I have seen a few todo apps that update their app badges at midnight, always showing the correct number of due tasks. They do this without the use of Push Notifications - so my question is: how do they do this? Do they use local notifications - if so, do these get called when the device is turned off? I'm a little confused and would appreciate some input.

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
