通过Cocoa API获取计算机类型和其他硬件详细信息 [英] Getting the Machine Type and other Hardware details through Cocoa API

问题描述

在iOS上，有一个 UIDevice 类它可以让你得到吨的关于设备型号，操作系统等的好信息...

我在Mac上寻找等效的东西。我知道从命令行调用 system_profiler ，但即使 mini 设置需要几秒钟来获取任何信息。 / p>

我有兴趣快速获取机器类型（Macbook Air，Mac Mini等），操作系统版本和其他快速机器细节从Mac应用程序。细节将被用作支持从应用程序内发送的电子邮件的页脚。是否有任何等效的UIDevice，或另一种快速方式获得一些信息，可以帮助描述用户的机器？

解决方案

  #include< stdlib.h> 
 #include< stdio.h> 
 #include< sys / types.h> 
 #include< sys / sysctl.h> 
 
 +（NSString *）machineModel 
 {
 size_t len = 0; 
 sysctlbyname（hw.model，NULL，& len，NULL，0）; 
 
 if（len）
 {
 char * model = malloc（len * sizeof（char））; 
 sysctlbyname（hw.model，model，& len，NULL，0）; 
 NSString * model_ns = [NSString stringWithUTF8String：model]; 
免费（模型）; 
 return model_ns; 
} 
 
 return @Just a Apple Computer; // incase模型名称无法读取
} 
  

On iOS, there is a UIDevice class which lets you get tons of great info about the device model, operating system etc…

I am looking for something equivalent on the Mac. I know about calling system_profiler from the command line, but even the mini setting takes several seconds to get any info.

I am interested in fast ways to get the machine type (Macbook Air, Mac Mini, etc…), OS version, and other quick machine details from within a Mac App. The details are going o be used as a footer on support emails sent from within the app. Is there any equivalent to UIDevice, or another fast way to get some info that could help describe a user's machine?

解决方案

#include <stdlib.h>
#include <stdio.h>
#include <sys/types.h>
#include <sys/sysctl.h>

+(NSString *) machineModel
{
    size_t len = 0;
    sysctlbyname("hw.model", NULL, &len, NULL, 0);

    if (len)
    {
        char *model = malloc(len*sizeof(char));
        sysctlbyname("hw.model", model, &len, NULL, 0);
        NSString *model_ns = [NSString stringWithUTF8String:model];
        free(model);
        return model_ns;
    }

    return @"Just an Apple Computer"; //incase model name can't be read
}
