- 每次编译后生成的 dSYM 文件
dSYM 文件里存储了函数地址映射，这样调用栈里的地址可以通过 dSYM 这个映射表能够获得具体函数的位置。一般都会用来处理 crash 时获取到的调用栈 .crash 文件将其符号化
<!-- 1、 通过 Xcode 进行符号化-->
将 .crash 文件，.dSYM 和 .app 文件放到同一个目录下，打开 Xcode 的 Window 菜单下的 organizer，再点击 Device tab，最后选中左边的 Device Logs。选择 import 将 .crash 文件导入就可以看到 crash 的详细 log 了。
<!-- 2、通过命令行工具 symbolicatecrash 来手动符号化 crash log -->
本文的重点
export DEVELOPER_DIR=/Applications/Xcode.app/Contents/Developer
symbolicatecrash appName.crash appName.app > appName.log
- 查找symbolicatecrash 工具的目录
在Xcode目录下查找/Applications/Xcode.app/Contents
find . -name 'symbolicatecrash' -ls
/Applications/Xcode.app/Contents/SharedFrameworks/DVTFoundation.framework/Versions/A/Resources/symbolicatecrash
<!-- 便于以后的使用，最好采用ln ，这样避免拷贝，尤其是后台的工程师尤其注意这点-->
devzkndeMacBook-Pro:LatestBuild devzkn$ ln -s /Applications/Xcode.app/Contents/SharedFrameworks/DVTFoundation.framework/Versions/A/Resources/symbolicatecrash ~/bin
devzkndeMacBook-Pro:LatestBuild devzkn$ ls -lrt ~/bin
