Initial data

Question

Does anyone know where I can find an example to make this case? 2 objects: Catalog of books and books. One to many relationship between. I found a lot of bananas to explain how to make a book of the selected directory (tableview) appear, but not for the "double" table view, which I just guess. In the first view of the table, the entire catalog of books will be presented, and after selecting the second table will display all the books of the selected catalog. (The last choice can finally give these books)

I am trying to figure out how to make a link from a book to a directory with an attitude. (with nspredicate?)

Are you giving me a specific example (or a link to that) to help me understand?

Answer 1

Begginer is here too, but the sample code for Basic Data Recipes seems to be very similar to what you are looking for.
