问iOS:如何确定CPU类型，例如A4或A5，或指令集架构arm6或arm7？

EN

std::string GetCPUModel()
{
    // you can compare results with https://www.theiphonewiki.com/wiki/List_of_iPhones

    struct utsname systemInfo;
    uname(&systemInfo);

    std::string version(systemInfo.version);

    size_t cpuModelPos = version.find("RELEASE_");

    if (cpuModelPos != String::npos)
    {
        // for example: will return "ARM64_S8000" - for iPhone S6 plus
        return version.substr(cpuModelPos + strlen("RELEASE_"));
    }

    return {};
}
