How do I make an google calendar feed in an iphone app?

I Want to implement a calendar in my TabBar application, it is supposed to show a google-calendar that updates it self (or already contains the feed at that moment) on a "new tab". I couldn't find any开发者_JAVA技巧thing that really helped me so I'm asking it now instead and please give a beginners kind of answer to me.

You've got a fair amount of research ahead of you. You couldn't find anything? Hmm. Search stackoverflow for "google calendar iphone" and check out the first page of hits. After reading up a bit, try coming back with specific questions. It's going to depend a lot on how much control you want over the calendar info.
