如何清除徽章数量，同时preserving通知中心 [英] How to clear badge number while preserving notification center

问题描述

我用 [UIApplication的sharedApplication] setApplicationIconBadgeNumber：0] 清除证件号码。它工作正常，但远程通知在同一时间将被删除。

I use [[UIApplication sharedApplication] setApplicationIconBadgeNumber:0] to clear badge number. It works fine but remote notifications are removed at the same time.

有许多其他的问题，清除通知中心，但我不希望以清除它们。我只是想清楚了，而preserving通知徽章的数量。

There are many other questions to clear notification center but I would NOT like to clear them. I just want to clear number of badge while preserving notifications.

有没有办法实现这一目标？

Is there any way to achieve this?

推荐答案

一个哈克的办法解决这是徽章数量设置为负值。负值并不在主屏幕上显示，并因为他们是非零的，它们不会导致通知中心得到清除。

One hacky way around this is to set the badge count to a negative value. Negative values aren't shown on the home screen and since they're non-zero, they don't cause the notification center to get cleared.

尝试 [UIApplication的sharedApplication] setApplicationIconBadgeNumber：-1]。，看看它是否会导致您需要的用户面临着行为

Try [[UIApplication sharedApplication] setApplicationIconBadgeNumber:-1] and see if it results in the user facing behavior that you want.
