Unable to find CFNetwork in Xcode

I am trying to use CFNetwork in my app so I tried adding CFNetwork.framework from the Edit Target dialog in Xcode.

The interesting thing is that CFNetwork is not visible in the dialog box at all.

Am I missing anything开发者_JAVA技巧? Do I have to add/install CFNetwork in some other way?

Thanks in advance.

CFNetwork is part of CoreServices.framework, so you should add CoreServices. The definitive tool to find this out is to use search in Xcode's documentation viewer. (Almost) each documentation page includes the relevant Framework header.
