推荐答案

您可以在/System/Library/CoreServices/SystemVersion.plist中读取属性列表， 键，这是OS X安装程序应用程序的作用。下面是一个例子：

You can read the property list at "/System/Library/CoreServices/SystemVersion.plist and extract the "ProductVersion" key, this is how the OS X installer application does it. Here's an example:

NSString *versionString;
NSDictionary * sv = [NSDictionary dictionaryWithContentsOfFile:@"/System/Library/CoreServices/SystemVersion.plist"];
versionString = [sv objectForKey:@"ProductVersion"];

或者，命令 swvers -productVersion 也会这样做。

Alternatively, the command swvers -productVersion will do the same.
