iPhone: How do I get the title of a PDF document from within the document?

Assuming I have extracted the CGPDFDictionaryRef from a PDF document using the iPhone SDK, how do I get the document's title from the dictionary? More generally, how can I get a list of the keywords for that dictionary? In theory I could ask the customer, but surely there must be some canonical keywords? Is there a list somewhere?

Update: I found this link which gives the common keys. To answer my own question, you can look these up directly in the dictionary returned by CGPDFDocumentGetInfo(pdfDocumentRef).

The dictionary key you're looking for is kCGPDFContextTitle.

Here's your list of keys.

Edit: I'm not sure. I haven't actually used CGPDF -- was just giving an educated guess based on how other Apple frameworks work.
