Use GData for objective-c.

You need to do a read-only checkout from google code, the command is -

svn checkout gdata-objectivec-client.googlecode.com/svn/trunk gdata-objectivec-client-read-only

check this out. for checkout instructions.

Also this article helped me - how to use Google API's from iOS
