Switch to use Core Data during development?

I decided to switch to use Core Data to save all the data in my navigation application. What are the steps necessary to make Core Data available in my application?

I don't want to start a new project with the check box 'Use Core Data for my application' and copy all the existing codes to the new pr开发者_StackOverflow社区oject.

Anybody has any guides or tutorial?

Thanks,

You need a CoreData stack consisting of:

1. NSPersistentStoreCoordinator

2. NSManagedObjectModel

3. NSManagedObjectContext

The easiest is probably to create a dummy project with CoreData enabled and then to copy the stack from the App-Delegate to your project. Don't forget to link in the CoreData Framework.

Also here is the link to Apple's Core Data Tutorial As a side note you don't have to use Core Data, you can use SQL Lite, I have found it to be a little easier starting out if you are all ready familiar with the basics of SQL.
