问题描述
我使用 [[UIApplication sharedApplication] setApplicationIconBadgeNumber:0] 清除徽章编号.它工作正常，但同时删除了远程通知.
I use [[UIApplication sharedApplication] setApplicationIconBadgeNumber:0] to clear badge number. It works fine but remote notifications are removed at the same time.
还有许多其他问题需要清除通知中心，但我不想清除它们.我只想在保留通知的同时清除徽章数量.
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.
有什么办法可以实现吗?
Is there any way to achieve this?
推荐答案
解决此问题的一个技巧是将徽章计数设置为负值.负值不会显示在主屏幕上，而且由于它们非零，因此不会导致通知中心被清除.
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 sharedApplication] setApplicationIconBadgeNumber:-1] 并查看它是否会导致您想要的面向用户的行为.
Try [[UIApplication sharedApplication] setApplicationIconBadgeNumber:-1] and see if it results in the user facing behavior that you want.
