本文开启ios原生虚拟内存教程只适合于 iOS 5.1.1~6.1.2系统,iOS 6.1.2 对iPhone4的内存要求太高了,打开没几个软件就出现很多LowMemory的错误报告log,成功开启虚拟内存即可解决问题(就像Win PC用硬盘空间弥补内存空间不足的情况)。
我按照内存使用率,从高到低,将部分显出出来,给懂的人看,有图有真相!
一共运行88个程序,包括真实赛车3,英雄战歌等多款大作,自带的512M内存,只剩下8824K自由空间,而此时虚拟内存调用320MB磁盘空间,完全感觉不到丝毫卡~
以下是相关文件说明,如果觉得不好,把com.apple.virtualMemory.plist和com.apple.dynamic_pager.plist删除,把com.apple.SpringBoard.plist 还原,然后在命令控制台中输入reboot就可以恢复到之前的时候,不用从刷手机的:
com.apple.virtualMemory.plist 放在 /private/var/preferences
com.apple.dynamic_pager.plist 放在 /System/Library/LaunchDaemons
在 /System/Library/LaunchDaemons/com.apple.SpringBoard.plist 必须进行手动的修改,修改内容往下看。(记得备份)
在 /private/var 里新建VM的文件夹,权限设置如图:
全部完成后,重启手机,/private/var/VM 出现swapfile0就说明成功。
com.apple.SpringBoard.plist 按照规则添加红色部分,建议使用iFile进行修改:
