My first question. I have a Categories Entity. I want to be able
to have categories that are children of categories. I am not sure
how to build a relationship for this. Suggestions on how to do it,
and explanations on why you would do it that way would greatly
appreciated.
Just create a relationship on Category with a target entity of
Category. It will point to itself.
I want to be able to link Photographs to Albums, and want to be
able to put the same image in multiple Albums. I had thought maybe
another Entity between Albums and Photographs, but I am not sure if
that would work the way I would expect it too.
Create a to-many relationship on Photograph that points to the Albums
entity (you probably actually want to call this "Album"). Core Data
will handle the rest.
