Save NSArray into Core Data object

I'm not proficient, but you have to make a core data model in the interface for that which is like making an xml file, but with fields (very easy), and then you have to make a number of objects that handle the memory of the variables. It's something like one object for a persistent store, and then one object that mangages the persistent store and then a persistent store object or something. It's actually very clear if you read up on it in the documentation under Core Data or Persistant Store.

The array can be saved as one object or, better, as multiple objects.
