[英]Getting Mac Model number in Cocoa
I'm making a OS X app where I need to get the Mac model, for example: 我正在制作一个OS X应用程序,我需要获取Mac模型,例如:
iMac11,3
MacBook3,1
And so on. 等等。 Is there any class, or function to get it?
是否有任何课程或功能得到它?
This information is available via. 这些信息可通过。
sysctl
: sysctl
:
#include <stdlib.h>
#include <stdio.h>
#include <sys/types.h>
#include <sys/sysctl.h>
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);
printf("%s\n", model);
free(model);
}
The API for that would be in the IOKit. 它的API将在IOKit中。 Looking in the IORegistryExplorer app on my laptop, I see that the first node from the root of the IOService tree is an IOPlatformExpertDevice, with a entry under the key "model" equal to "MacBookPro6,1"
在我的笔记本电脑上查看IORegistryExplorer应用程序,我看到IOService树根的第一个节点是IOPlatformExpertDevice,在“model”键下的条目等于“MacBookPro6,1”
While not using a direct Cocoa API, you could use NSTask to execute the "system_profiler" command line tool. 虽然不使用直接Cocoa API,但您可以使用NSTask来执行“system_profiler”命令行工具。 If you execute the tool as: "system_profiler SPHardwareDataType" it will give you a smaller output which could be filtered to extract the model identifier.
如果您执行以下工具:“system_profiler SPHardwareDataType”,它将为您提供较小的输出,可以对其进行过滤以提取模型标识符。

I found an example using sysctl programmatically: 我找到了一个以编程方式使用sysctl的示例:
int mib[2];
size_t len = 0;
char *rstring = NULL;
mib[0] = CTL_HW;
mib[1] = HW_MODEL;
sysctl( mib, 2, NULL, &len, NULL, 0 );
rstring = malloc( len );
sysctl( mib, 2, rstring, &len, NULL, 0 );
NSLog(@"%s", rstring );
free( rstring );
rstring = NULL;
我不确定是否有通过Cocoa获取它的确切方法,但你可以使用NSTask并通过shell获取它。
sysctl hw.model
