This app uses the uses a basic Rails 3 app with a REST API to explore synching data from a remote API to a local CoreData store.
To get up and running, you'll need the latest Rails 3 beta (to run the demo app). To start up a server for the demo app, inside the SampleRestApp folder, run the following command:
This will boot up a local server on port 3000, which the iPhone app is configured to use.
The point is to have a reusable means of synching a remote API to a local CoreData stack.
I'm using the HTTPRiot to access the API as its an awesome library for interacting with JSON/XML REST APIs. There is a degree of coupling to its HRRestModel class at the moment but that can be refactored away; its not that important right now.
