iPhone:推送通知后如何删除徽章？

Question

删除应用图标上的徽章的代码是什么？当我收到推送时,我需要在单击按钮时将其删除!

Answer 1

objC:

[UIApplication sharedApplication].applicationIconBadgeNumber = 0;

迅捷:

UIApplication.sharedApplication().applicationIconBadgeNumber = 0;

Answer 2

您可以通过在代码中添加以下行来从推送通知中删除徽章

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

Answer 3

对于iOS5,只设置徽章编号不会删除通知中心的推送通知.你必须这样做......

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

我已经测试了这个.看起来cancelAllLocalNotifications方法也适用于通知中心的推送通知.
