Just to expand on pcperini's answer. As he mentions you will need to add the following code to yourapplication:didFinishLaunchingWithOptions: method; [[UIApplication sharedApplication] setApplicationIconBadgeNumber: 0]; [[UIApplication sharedApplication] cancelAllLocalNotifications]; You Also need to increment then decrement the badge in your application:didReceiveRemoteNotification: method if you are trying to clear the message from the message centre so that when a user enters you app from pressing a notification the message centre will also clear, ie; [[UIApplication sharedApplication] setApplicationIconBadgeNumber: 1]; [[UIApplication sharedApplication] setApplicationIconBadgeNumber: 0]; [[UIApplication sharedApplication] cancelAllLocalNotifications];
