iOS 代码混淆的简单使用
1.工具下载 http://stevenygard.com/projects/class-dump/ 选择dmg安装包
2.打开终端输入:open/usr/local/bin
3.
4.修改权限在终端键入: sudo chmod 777 /usr/local/bin/class-dump
5.使用Python3自动发包工具解压包后缀为zip
Python脚本如下（上传蒲公英脚本可以忽略）
#!/usr/bin/env python
#coding=utf-8
import os
import requests
import webbrowser
import subprocess
import shutil
\’\’\’
使用注意事项:该脚本基于python3.6
1、将工程的编译设备选成 Gemeric iOS Device
2、command + B编译
3、执行脚本文件

6.解压出Payload文件夹，.app就是我们的目标文件
7.在终端使用命令class-dump -H[.app文件路径] -o[输出文件夹路径]，就会生成我们需要解析成.h文件有相对应的方法及属性
8.混淆代码的方法通过shell脚本来实现，同时需要一个文档写入我们需要混淆的方法名与变量名
9.打开终端，cd到文件所在目录，使用touch命令 创建confuse.sh（混淆脚本） func.list（混淆方法，函数列表）
10.添加run script命令Targrt–build phases—new run script phase（把shell脚本运行）
11.生成混淆文件 就是说明混淆成功了
有些地方不能混淆：storyboard,init,系统方法等
