MAC 系统信息的获取

在项目中引入IOKit.framework来替换AppleAHCIDiskDriver字符串来获取相应的信息,所有的Key 在IOKit/IOKitKeys.h中都有定义

- (void)iotest
{
    io_iterator_t iterator;
    kern_return_t kr;
    io_object_t   driver;
    
    CFMutableDictionaryRef matchDictionary = IOServiceMatching("AppleAHCIDiskDriver");
    kr = IOServiceGetMatchingServices(kIOMasterPortDefault, matchDictionary, &iterator);
    if (kr != kIOReturnSuccess)
    {
        return;
    }
    
    while ((driver = IOIteratorNext(iterator)) != 0)
    {
        CFMutableDictionaryRef properties = NULL;
        kr = IORegistryEntryCreateCFProperties(driver,
                                               &properties,
                                               kCFAllocatorDefault,
                                               kNilOptions);
        if (kr != kIOReturnSuccess || properties == NULL)
        {
            continue;
        }
        
        NSLog(@"%@",(__bridge NSDictionary*)properties);
    }
}

其中AppleAHCIDiskDriver 这个key可以通过IORegistryExplorer工具看到更多更详细的Key,而设备基本信息可以通过IOPlatformExpertDevice获取.
