• 1、cd 到 appName.dYSM/Contents/Resources/DWARF/

• 2、终端执行 xcrun atos -o ./appName -l 模块加载地址 崩溃地址 -arch arm64 命令，例如：这里的 0x00000001015afccc 这一个为崩溃地址，模块加载地址为 0x00000001015afccc - 0x747ccc（7634124的十六进制），为0x100E68000，那么终端输入如下：

xcrun atos -o ./HLLCourseLive -l 0x100E68000 -arch arm64

回车后，后续再输入想要符号化的地址，例如这里最后的崩溃地址：0x00000001015afccc 等，如下

有时候在符号化的时候会发现符号化出来的信息对应不上，这时候就需要确定好崩溃机型的arm架构了，具体的可以看 bugly→ 其他信息→ App Arch 字段

需要注意的是，这里只能加载地址显示为本项目非系统库的，如果需要加载系统SDK的则需要用IDA或者是otool解析了

otool -v -arch arm64 -s __TEXT __objc_methname <KitAddress> <Address>

eg:
otool -v -arch arm64 -s __TEXT __objc_methname ./CoreFoundation 0x0000000195207b90
