下面的方法可以将 sysctl hw.model 获取的苹果电脑硬件型号转换为容易看懂的形式。

然后在程序中加入如下代码即可：

  1. #import <sys /sysctl.h>
  2.  
  3. + (NSString *)hardwareModel
  4. {
  5.     static NSString *hardwareModel = nil;
  6.     if (!hardwareModel) {
  7.         char buffer[128];
  8.         size_t length = sizeof(buffer);
  9.         if (sysctlbyname("hw.model", &buffer, &length, NULL, 0) == 0) {
  10.             hardwareModel = [[NSString allocWithZone:NULL] initWithCString:buffer encoding:NSASCIIStringEncoding];
  11.         }
  12.         if (!hardwareModel || [hardwareModel length] == 0) {
  13.             hardwareModel = @"Unknown";
  14.         }
  15.     }
  16.     return hardwareModel;    
  17. }
  18.  
  19. + (NSString *)computerModel
  20. {
  21.     static NSString *computerModel = nil;
  22.     if (!computerModel) {
  23.         NSString *path, *hardwareModel = [self hardwareModel];
  24.         if ((path = [[NSBundle mainBundle] pathForResource:@"Macintosh" ofType:@"dict"])) {
  25.             computerModel = [[[NSDictionary dictionaryWithContentsOfFile:path] objectForKey:hardwareModel] copy];
  26.         }
  27.         if (!computerModel) {
  28.             char buffer[128];
  29.             size_t length = sizeof(buffer);
  30.             if (sysctlbyname("hw.machine", &buffer, &length, NULL, 0) == 0) {
  31.                 computerModel = [[NSString allocWithZone:NULL] initWithCString:buffer encoding:NSASCIIStringEncoding];
  32.             }
  33.         }
  34.         if (!computerModel || [computerModel length] == 0) {
  35.             computerModel = [[NSString allocWithZone:NULL] initWithFormat:@"%@ computer model", hardwareModel];
  36.         }
  37.     }
  38.     return computerModel;
