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

bulidIPA()

uploadIPA('%s/Payload.ipa'%packBagPath)

openDownloadUrl()

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
