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

>>> 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}
