Good iPhone SDK tutorials

Hello,

I'm looking for good iPhone SDK tutorials in terms of using Interface Builder to set up views (like using the Navigation Controller or Tab Bar Controller). I can't seem to set one up correctly and add it as a sub view for the main app window to display. I always get a blank screen and I've yet to find something that helps me.

Any help would be great.
