    For PDF parsing on iOS, use the Quartz API.

    For an example of an app which makes use of this API, see this reader.

    To extract the specific information you’re interested in, you will need to read the PDF document structure specification and figure out which dictionaries it’s in (or, if you’re lucky find some sample code).
