How to add core data to 2nd level view controller in existing project

[alextattoo]

Hi , i have a table view with couple of rows and each row open a new detail view with keypad panel for user input. So i want to save that input (2-3 digits number) ,but don't know how to add core data to my second view (detail) controller.Any ideas?

When you're first starting out with with Core Data, use one of the project templates that includes Core Data support. There's a whole bunch of stuff you need to learn how to do, and trying to add it to an existing project after the fact is difficult and involved.

I've done several Core Data based applications, and I don't think I could list all the housekeeping you have to do to set it up. I'd have to go digging. In fact, I'd probably create an empty Core Data template app and look at what's there.

Assuming you are registered as a developer with Apple you can download a number of core data samples eg: core data books. Possibly you want a simpler example to start with. You will find lots by googling but make sure the database structure is correct before you start using any core data setup in your app.

In Xcode 4.2 it's not obvious how to get a core data project. Choose master-detail project for example, tick 'use core data' and untick storyboard if you are not using that approach. Same goes for ARC. Untick if you want to use the older way of working with retain release.

Once you have a blank project look at the files. You will see 'projectname'.xcdatamodeld. Click on this and then you are at the start of learning core data. Add your fields & use Editor, create NSManagedObject subclass to create the XCode files to manage the data.

I already have a working core data project all i want is to add it to another project i have to store the inputs
