清除applicationIconBadgeNumber而不删除通知不起作用 [英] Clear applicationIconBadgeNumber without removing notifications not working

问题描述

我已经阅读了几篇文章(例如这篇 https://forums.developer. apple.com/thread/7598 )设置

I've read in a few posts (like this one https://forums.developer.apple.com/thread/7598) that setting

    application.applicationIconBadgeNumber = -1

applicationDidBecomeActive或applicationWillEnterForeground上的

允许我清除徽章编号，而无需从通知中心删除通知.当我将application.applicationIconBadgeNumber设置为负数(如-1)时，它将清除Notification Center中的所有通知.是否有另一种清除徽章编号而不删除notifications的方法?

on applicationDidBecomeActive or applicationWillEnterForeground would allow me to clear the badge number without removing the notifications from the notification center. When I set application.applicationIconBadgeNumber to a negative number (like -1) it clears all my notifications from the Notification Center. Is there another way to clear the badge number without removing the notifications?

推荐答案

UIApplication.sharedApplication.applicationIconBadgeNumber = -1;

我已经在iOS 12.2中对其进行了测试，并且可以通过远程通知正常运行.

I have tested it in iOS 12.2 and it's working fine for me with remote notification.

通过将接收到的远程通知保存在通知中心中来清除徽章计数.

It is clearing badge count by keeping received remote notification in notification centre.

代码段供参考:

- (void)applicationDidBecomeActive:(UIApplication *)application {
    UIApplication.sharedApplication.applicationIconBadgeNumber = -1;
}
