2.下载工具restore-symbol，在终端执行

git clone --recursive https://github.com/tobefuturer/restore-symbol.git

下载成功之后运行，然后执行

 cd restore-symbol && make

3.解析bug位置

1.找到项目中的.app文件，Frameworks或者Products内，拷贝到restore-symbol文件夹内；

2.然后终端执行会生成一个虚拟逛店UAT-symbol文件；

./restore-symbol -o 虚拟逛店UAT-symbol 虚拟逛店UAT

3.定位具体bug位置，此时架构师arm64，0x1026dc000是基址

atos -arch arm64 -o 虚拟逛店UAT-symbol -l 0x1026dc000 0x00000001028aa384 0x00000001028a9b20 0x00000001028ac9c0 0x00000001028ab91c 0x00000001028af90c 0x00000001028d3644
