does someone know where i can find example to do that case ? 2 entities : Catalogue of books and Books. One relation to-Many between. I found many tuto to explain how to make appears A book of selected catalogue (tableview) but none for a "double" tableview which is simple i suppose. The first tableview will present all the book's catalogue and after selection, a second tableview will list all the books of a selected catalogue.(A last selection could finaly give datas of the book)
I try to understand how to make link from book to catalogue with the relation. (with nspredicate?)
culd you give me a concrete example(or tuto link) to help me understand ?
