获取我Mac的计算机名称

Question

如何在Mac上获取计算机的名称？我说的是与在"软件"下的System Profiler中找到的名称相同的名称.

Answer 1

目标C.

我要找的名字是:

[[NSHost currentHost] localizedName];

它返回"Jonathan的MacBook"而不是"Jonathans-Macbook",或者"jonathans-macbook.local" name.

对于Swift> = 3使用.

if let deviceName = Host.current().localizedName {
   print(deviceName)
}

Answer 2

NSHost就是你想要的:

NSHost *host;

host = [NSHost currentHost];
[host name];

Answer 3

我使用sysctlbyname("kern.hostname"),它不会阻塞.请注意,我的帮助方法只应用于检索字符串属性,而不是整数.

#include <sys/sysctl.h>

- (NSString*) systemInfoString:(const char*)attributeName
{
    size_t size;
    sysctlbyname(attributeName, NULL, &size, NULL, 0); // Get the size of the data.
    char* attributeValue = malloc(size);
    int err = sysctlbyname(attributeName, attributeValue, &size, NULL, 0);
    if (err != 0) {
        NSLog(@"sysctlbyname(%s) failed: %s", attributeName, strerror(errno));
        free(attributeValue);
        return nil;
    }
    NSString* vs = [NSString stringWithUTF8String:attributeValue];
    free(attributeValue);
    return vs;
}

- (NSString*) hostName
{
    NSArray* components = [[self systemInfoString:"kern.hostname"] componentsSeparatedByString:@"."];
    return [components][0];
}

使用必须添加到项目中的SystemConfiguration.framework:

#include <SystemConfiguration/SystemConfiguration.h>

...

// Returns NULL/nil if no computer name set, or error occurred. OSX 10.1+
NSString *computerName = [(NSString *)SCDynamicStoreCopyComputerName(NULL, NULL) autorelease];

// Returns NULL/nil if no local hostname set, or error occurred. OSX 10.2+
NSString *localHostname = [(NSString *)SCDynamicStoreCopyLocalHostName(NULL) autorelease];
