iPad UI organization advices

Question

Hi there,

I'm doing an iPad application with a map. I want to have a top bar (toolbar), under a 156px height and all width block where i will display information and under an MKMapView.

On my second block, I will have a UIPageControl with a couple a view. A button will also allow the user to hide this block, and the map will be resized all screen (minus the top bar).

So basically, the app would almost look like the WeatherBug app.

I have an app delegate for now, with a UIViewController mapViewController. In this view, how should I organize myself to do the same kind?

Thank you!
