开始符号化
解析上面第8行如下：
8 LC 0x10122f61c 0x101088000 + 1734172
# 运行时地址 = 运行时起始地址+偏移地址
验证 （运行时地址 = 运行时起始地址+偏移地址）
# python 中hex()函数转换10进制为16进制，int('0x10',16)函数转16进制为10进制
# 如：hex(16) ==> 0x10 int('0x10', 16) ==> 16
$ python
Python 2.7.10 (default, Feb 22 2019, 21:55:15)
[GCC 4.2.1 Compatible Apple LLVM 10.0.1 (clang-1001.0.37.14)] on darwin

>>> hex(0x101088000 + 1734172)
'0x10122f61c'
>>>
输入格式如下
# atos -arch arm64 -o LC.app.dSYM/Contents/Resources/DWARF/LC -l 堆栈起始地址 运行时地址 运行时地址 运行时地址
# 多个运行时地址以空格隔开
# 只输入堆栈起始地址会进入交互模式，然后输入一个运行时地址就会符号化一行
# -arch arm64 指定某个架构
$ atos -arch arm64 -o LC.app.dSYM/Contents/Resources/DWARF/LC -l 0x101088000 0x10122f61c
输出结果，可以看出在HqUserSetPsVC.m的第171行出现了问题
-[HqUserSetPsVC getSetPsCheckCode:] (in LC) (HqUserSetPsVC.m:171)
脚本代码
#!/bin/bash
# 0x104c84000 0x0000000104cae4b4
echo "Enter App Info -> app_name start_address runtime_address"
read app_name start_address runtime_address
# xcrun dwarfdump --uuid ${app_name}.app.dSYM
atos -arch arm64 -o ${app_name}.app.dSYM/Contents/Resources/DWARF/${app_name} -l \
${start_address} ${runtime_address}
