Viewing Core Data within an App

I was thinking of writing some UIViewControllers to display the data in my Core Data stores while developing and testing an app.

I was thinking of something like this: A view controller that allows the user to select parameters to be passed into a fetch request, then a table view controller to list the fetch results, and finally a view controller to display the data in a particular entry from the fetch results.

Does anyone know of some open source code already similar to this, or a different approach I should take for monitoring my data?

NOTE: To clarify, I'm talking abou开发者_运维问答t a generic solution that could be put into any app using CoreData with minimal configuration.

Not a direct answer to your question but there is a new app in the mac app store which allows you to view and manipulate Core Data Stores. While it doesn't integrate in with your own app (and its not the cheapest software out there) you might find it helpful. I stumbled across it a few moments ago and thought of your question here.
