crash 堆栈定位

##crash 日志定位crash 位置

首先是获取线上版本的dSYM文件, 并在dSYM文件找到app文件 ,拷贝dSYM文件和app文件到同一目录, 然后执行命令:

先cd到改目录执行
运行脚本   xcrun atos --arch arm64 -o app  -l 0x0000000101844a6c 0x00000001028814D8

注意  0x0000000101844a6c 是起始地址  , 0x00000001028814D8 是结束地址 与下面的+ 17025644相关(0x0000000101844a6c + 17025644 得到的)
  app 是上面的APP文件名

如:

stack:(
"0   xxxxProject         0x0000000101844a6c xxxxProject + 17025644",    0x00000001028814D8

"1   xxxxProject         0x00000001018437f0 xxxxProject + 17020912", 0x000000010287EFE0

"2   xxxxProject         0x0000000101843418 xxxxProject + 17019928", 0x000000010287E830

"3   xxxxProject         0x0000000100c339c4 xxxxProject + 4372932",  0x000000010105F388
"4   libdispatch.dylib                   0x00000002038b4a38 <redacted> + 24",
"5   libdispatch.dylib                   0x00000002038b57d4 <redacted> + 16",
"6   libdispatch.dylib                   0x0000000203859c80 <redacted> + 684",
"7   libdispatch.dylib                   0x0000000203866030 <redacted> + 372",
"8   libdispatch.dylib                   0x00000002038668d4 <redacted> + 128",
"9   libsystem_pthread.dylib             0x0000000203a961b4 _pthread_wqthread + 464"
)

运行后的结果
