SInt32 major, minor, bugfix;
Gestalt(gestaltSystemVersionMajor, &major);
Gestalt(gestaltSystemVersionMinor, &minor);
Gestalt(gestaltSystemVersionBugFix, &bugfix);

You could use the same technique that Apple's code uses...
您可以使用 Apple 代码使用的相同技术...
NSDictionary *systemVersionDictionary =
[NSDictionary dictionaryWithContentsOfFile:
@"/System/Library/CoreServices/SystemVersion.plist"];
NSString *systemVersion =
[systemVersionDictionary objectForKey:@"ProductVersion"];
Apple does exactly this to fill in the version number for various system utilities in the function _CFCopySystemVersionDictionaryhere:
Apple 正是这样做的，以在_CFCopySystemVersionDictionary此处的函数中填写各种系统实用程序的版本号：

For OS X 10.10+ I think using NSProcessInfois an easier and safer way to do that:
对于 OS X 10.10+，我认为使用NSProcessInfo是一种更简单、更安全的方法：
NSOperatingSystemVersion version = [[NSProcessInfo processInfo] operatingSystemVersion];
NSLog([NSString stringWithFormat:@"%ld.%ld.%ld", version.majorVersion, version.minorVersion, version.patchVersion]);
