UIApplication 图标徽章编号在重新安装时仍保留
重新安装时不会删除 UIApplication 徽章编号。
如果我在徽章具有非零值时卸载应用程序，然后重新安装它，徽章仍会出现在新安装中。
我通过以下方式更新徽章编号：
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:badgeNumber];
尝试找到解决方案 - 应用程序终止时发出一些通知，以便我可以删除徽章...无法使用 applicationWillTerminate 来完成。有什么建议吗？
The UIApplication badge number is not deleted at reinstall.
In case I uninstall the application when the badge has a non zero value, and then re-install it, the badge still appears in the new installation.
I update the badge number in the following manner:
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:badgeNumber];
Tried to find a solution - some notification when the application terminates so I can remove the badge... Couldn't make it with applicationWillTerminate. Any suggestions?

苹果实际上做出了回应，这是预期的行为，卸载后徽章会保留很短一段时间（恰好适用于立即重新安装的情况）。
Apple actually responded and this is the expected behavior, the badge remains for a short period after uninstall (exactly for the case of an immediate re-install).
尝试设置：
