iPhone and Core Data

Question

Hi, I need some understanding about using Core Data.

Can it be used to save and retrieve all of my objects used in my program?

Is there any simple example demonstrating this ?

I am having hard time finding one online.

Thanks for any replies.

Answer 1

This might not be the answer you ultimately vote up or mark as accepted, but it may prove useful if you haven't seen it already:

I found it endlessly useful personally.

Answer 2

They have to be managed objects, but you can convert them all to be - it's just that you still have to define the data model for them.
