以编程方式检索OS X磁盘分区UUID [英] Programmatically retrieve an OS X disk partition UUID

问题描述

我有一个分区路径.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.

解决方案

您可以使用磁盘仲裁框架(博客上也有一个很好的摘要. >

您可以使用kDADiskDescriptionMediaUUIDKey来获取UUID.亚伦·伯格哈特(Aaron Burghardt)在此邮件列表 thread 中对此进行了很好的描述.这是该链接的引文:

一旦有了DADisk，请使用DADiskCopyDescription来获取属性字典，在该字典中 使用密钥kDADiskDescriptionMediaUUIDKey查找UUID(有关其他密钥，请参见DADisk.h). 兴趣).注意，DADisk是IOMedia对象和描述字典的包装器 直接对应于IOMedia对象中的属性.另外，CFShow()可用于打印 描述字典到控制台.

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.

解决方案

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.
