You can remove badge from push notifications by adding the following lines to your code

通过在代码中添加以下代码，可以从推送通知中删除badge

(void)applicationDidBecomeActive:(UIApplication *)application
{
    [[UIApplication sharedApplication] cancelAllLocalNotifications];
    [UIApplication sharedApplication].applicationIconBadgeNumber = 0;
}

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，设置badge编号不会删除通知中心的推送通知。你必须这么做……

[[UIApplication sharedApplication] cancelAllLocalNotifications];
[UIApplication sharedApplication].applicationIconBadgeNumber = 0;

I already tested this. It looks like cancelAllLocalNotifications method also works with push notifications in notification center as well.

我已经测试了这个。看起来cancelAllLocalNotifications方法也可以在通知中心中使用推送通知。
