As for iOS5, just setting badge number won't remove those push notification in the notification center. You have to do this...
对于iOS5，仅设置徽章编号不会删除通知中心的那些推送通知。你必须这样做...
[[UIApplication sharedApplication] cancelAllLocalNotifications];
[UIApplication sharedApplication].applicationIconBadgeNumber = 0;
I already tested this. It looks like cancelAllLocalNotificationsmethod also works with push notifications in notification center as well.
我已经测试过了。看起来cancelAllLocalNotifications方法也适用于通知中心的推送通知。
