Custom Core Data entities

Question

How does one create a Core Data Entity that has custom objects within it?

E.g. An entity that has the possibility of holding, e.g. images, audio clips, a custom godzilla object.

How are these saved and loaded as well? Using NSData?

Answer 1

The best way would be to use a 'transformable' attribute. See the Core Data documentation here for more information:
