Question

I’m working on an app that needs to be able to open a PDF document and then save as a bundle containing this PDF and the core data object graph. The app should also open the custom bundle.

Any pointers on where to start?

Thanks

Answer 1

I’d say these two sources:

• Document-Based App Programming Guide for Mac
• Core Data Programming Guide

You certainly can use NSPersistentDocument. When you create your data model, you could create a root document object with a data object and external storage to store the PDF.

Or, use NSDocument, and handle the bundle loading and Core Data stack yourself.
