You can't do it in background if your app is suspended. But UILocalNotification supports recurrent notifications.
All you have to do is to declare the recurring interval: notif.repeatInterval = NSDayCalendarUnit;
You can find more details here.
Note that you can't set custom intervals. You must use the default ones provided by Apple.
