Retrieving Google Reader subscription list in iOS app

I need to retrieve Google Reader subscription list for a user in a iPhone app. I understand that there is no official API available, and I have kinda exhausted Google search already. Out of various开发者_高级运维 options, the closest I have found is [Using JSON Framework on iPhone - HELP!], can anyone share more details - sample code etc.

@WeNeedAnswers> Yes, the OPML format is what I am looking at. But I need to retrieve that directly from my iPhone app.

I'm writing an Objective-C wrapper for iOS based apps using GoogleReader API. The project, inspired by Pyrfeed, is available at https://github.com/zimok/GoogleReaderAPI-iOS

Note that is an ALPHA, and I'm doing an hard refactoring to make it work Asynchronous and using a delegate protocol.

For now there are some base API methods available. Take a look.
