使用 iSH App在iPhone上优选 Cloudflare IP

iSH 官网 ish.app

iSH 是一个项目，用于使用用户模式 x86 模拟器在 iOS 设备上本地运行 Linux shell 环境
该应用程序永远完全免费
下载

AppStore中搜索ish下载安装
步骤

1. 安装依赖

1	apk update && apk add -f wget curl bash
如果这里更新安装失败, 可以更换下代理节点
2. 下载优选代码.sh脚本 (Git项目: better-cloudflare-ip)

1	wget -N https://raw.githubusercontent.com/badafans/better-cloudflare-ip/master/shell/cf.sh
3. 开始优选

./cf.sh
开始优选的时候, 切记关闭代理
如果这里有权限问题, 执行: chmod u+x cf.sh
最后

后续优选IP, 只需输入 ./cf.sh 回车即可
