以编程方式检索OS X磁盘分区UUID(Programmatically retrieve an OS X disk partition UUID)

我有一个分区的路径。 如何在不使用终端命令的情况下以编程方式检索该分区的UUID？ 一个例子会更有帮助。

I have a path to a partition. How can I retrieve UUID of that partition programatically without using terminal commands? An example will be more helpful.

您可以使用磁盘仲裁框架（ Apple参考 ）。 Chris Suter在这篇博客中也有一个很好的总结。

您可以使用kDADiskDescriptionMediaUUIDKey获取UUID。 Aaron Burghardt在这个邮件列表线程中描述得很好。 以下是该链接的引用：

获得DADisk后，使用DADiskCopyDescription获取属性字典，您可以在其中找到带有密钥kDADiskDescriptionMediaUUIDKey的UUID（有关其他密钥的信息，请参阅DADisk.h）。 请注意，DADisk是IOMedia对象周围的包装，描述字典直接对应于IOMedia对象中的属性。 此外，CFShow（）对于将描述字典打印到控制台很有用。

You can use the Disk Arbitration framework (Apple reference). There is also a good summary at this blog by Chris Suter.

You can get the UUID by using the kDADiskDescriptionMediaUUIDKey. Aaron Burghardt described it well in this mailing list thread. Here is a quote from that link:

Once you have the DADisk, use DADiskCopyDescription to get a dictionary of properties, in which you will find the UUID with the key kDADiskDescriptionMediaUUIDKey (see DADisk.h for other keys that may be of interest). Note, a DADisk is a wrapper around an IOMedia object and the description dictionary corresponds directly to the properties in the IOMedia object. Also, CFShow() is useful for printing the description dictionary to the console.
