How can I scan links in a PDF Document? Do I have to use Quartz? Which methods/functions?
回答1:
Yes, you need to use Quartz. You have to parse it out from the PDF. This guide can help you.

I recommend reading the PDF specification so you will know what to look for.

The links are stored in the Annotations object so you will need some software to parse those.
