iOS app后台进入前台的这个库居然会自动清除角标，真是无语，还好我是老iOS

Hi @RichDaddyCashMany thank you for reaching out about this behavior.

I see you are asking about badge count being cleared and reset to zero when the app is foregrounded.

Actually, this is the default behavior. Please see our docs on iOS Badge Behavior.

If you want to prevent our SDK from automatically clearing badges set OneSignal_disable_badge_clearing to YES as a Boolean type in your .plist in Xcode.
