1、Mac电脑中新建一个文件夹restoresym
2、终端命令行 cd 到restoresym文件夹
3、在restoresym文件夹目录下 输入终端命令如下
git clone --recursive .git
得到结果

注意，此时二进制文件添加了可执行权限。
chmod +x APPName
然后执行终端命令如下
./restore-symbol APPName -o APPName_with_symbol
结果成功

=========== Finish ============
即在restore-symbol目录中得到了APPName_with_symbol，把APPName_with_symbol复制回APPName.app替换掉原来的APPName可执行文件，在XCode编译时，LLDB调试时可以看到完整的带符号的调试堆栈信息。
