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?
