Interface Design & View controller

[aspire]

Folks,

I am new to Iphone SDK and looking for guidance on this forum.

Although i have gone through dozens of video on iphone SDK, I am not sure how to put following interface together.

Let me walk you though interface..

- Main view has 2 buttons. One in top left - Settings. One in top right - Share.

-Top Left hand button navigates to 'Settings'. When pressed it opens a Tab based view to add/remove subscribed RSS. This new Tab window has 2 tabs in toolbar..first, to see subscribed RSS; Second, to see list of all listed RSS. This new Tab window also has Done button in top left to back to Main view.


-Top right hand button in Navigation is 'Share'. When pressed it gives a list of options to share article via Facebook, Twitter, email, and everything..

I know it sounds simple, but i am lost how to get started..
