LetMeBlock 安装提示

Makes mDNSResponder care about /etc/hosts on iOS 12, and load all entries on iOS 9+

In order to load all entries on iOS 9+, the memory limits defined in Version4 > Daemon > Override > com.apple.mDNSResponder.reloaded of the jetsam properties plist must be increased. This can be done either by manually editing the plist (and rebooting) or using jetsamctl's API, see here.

If in any cases the tweak does not seem to work, you either

• Reinstall LetMeBlock from Cydia
• Run the command killall -9 mDNSResponder; killall -9 mDNSResponderHelper as root
