如何以编程方式区分MacBook和Mac台式机? [英] How to distinguish MacBook and Mac desktops programmatically?

问题描述

我正在使用应区分MacBook和Mac台式机(iMac/Mac Pro)的Mac应用.

I'm working on a Mac app that should distinguish MacBook and Mac desktops (iMac/Mac Pro).

我想我可以用型号完成它.那我怎么得到型号呢?哪个字母表示它是笔记本电脑或台式机?还是还有其他更简便或更完善的方法?

I think I can get it done with model number. Then how I can get the model number? And which letter indicates it's a notebook or desktop? Or is there any other easier or better way?

推荐答案

您可以使用此小程序. NSLog输出以对其进行测试.

You can use this little program. NSLog the output to test it.

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

+ (NSString *)machineModel
{
    size_t length = 0;
    sysctlbyname("hw.model", NULL, &length, NULL, 0);      
    if (length) {
        char *m = malloc(length * sizeof(char));
        sysctlbyname("hw.model", m, &length, NULL, 0);
        NSString *model = [NSString stringWithUTF8String:m];
        free(m);
        return model;
    }
    return @"Unknown model";
}

它将提供与在终端上输入sysctl hw.model相同的输出.

It will provide the same output as entering sysctl hw.model on the terminal.
