Can I programmatically clear my app's notifications from the iOS 5 Notification Center?

Question

I would like to remove old notifications that my app has made from the iOS 5 Notification Center. Can I do this? If so, how?

Answer 1

To remove notifications from the Notification Center simply set your icon badge number to zero.

[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0]; 

This only works if the number changes, so if your app doesn't use the badge number you have to first set, then reset it.

[[UIApplication sharedApplication] setApplicationIconBadgeNumber:1]; [[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];
