lipo

• lipo：常用于多架构Mach-O文件的处理
  • 查看架构信息

    lipo -info inputMacOFile
    

  • 导出某种特定架构

    lipo inputMachOFile -thin ArchType -output OutputFile
    

  • 合并多种架构

    lipo inputMachOFile1 inputMachOFile2 -output OutputFile
    

举例

• 瘦身=导出单个架构
  • 导出arm64架构

    lipo -thin arm64 debugserver_orig -output debugserver_arm64
    

其中，arm64是从file中查看到包含的多个架构中的其中一个：
