Is it really this difficult to authenticate to Google Analytics?

[mfromin]

I am fairly new to Objective-C and iOS but not brand new.  I have built an app that accesses data from a web app via HTTP using Basic Authentication and then gets JSON content for use in a table view.  Not too difficult. 

Now I am looking to do what I would think is simple:

1 - Authenticate to our Google Apps account

2 - Extract Google Analytics data for a given URL on our web site

3 - Get that content via JSON

Is there no concise example of how to get a users logon data and pass it to Google?  The examples I have found here seem to have thousands of lines of code and reliance on numerous other libraries.  I can't believe that there is not some simple way (assuming I have our client ID and secret)  to get the user's name/password and then craft a URL to authenticate them.  Has my search of the internet just missed something?  Is there actually an easy way to do this?  Can it be done without these large and complex Google libraries?

Any suggestions/thoughts would be appreciated.
