Dear All,
I was wondering what is the best approach to the following scenario:
I have a library application where I intend to store my books under some
categories. Now I have a NSOutlineView to do that interface wise. But how
should I store the categories? The problem is that user should be allowed to
create as many categories and subcategories as they want, much like the
behavior of folders tree. Also I need to associate each book with a
category, and users should have freedom to change the book's category, just
like the case of moving the file from one folder to another.
Is there something in obj-C that I could use here or do I need to create my
own data structure to support this scenario?
Thanks a lot.
Regards
David
