Using google doc in an iPhone app

I'm looking for a way to integrate Googl开发者_运维百科e Docs in an iPhone app (basically, I want to write something in a spreadsheet).

I look'd in the Google API's page dedicated for mobiles (http://code.google.com/intl/fr-FR/mobile/more/#google-all), and I was unable to find out how to connect to google docs.

I found a project, Google Docs Cocoa Sample (http://code.google.com/p/googledocs-cocoa-sample/), but it doesn't compile w/ iOS 4.2.

Have you any source code related ?

Thank you for your help :)

Here is some working code (with lots of room for improvement, I admit). It connects to Google and will extract data from a online spreadsheet. In importCar a CSV file is read from GoogleDocs.

I am not at my development machine right now, and don't remember the version of the Google API I use, but IIRC the code compiles against version 1.7.

Export and authentication is in LoginViewController.
