I have a tabview controller to which I added a UIViewController to each tab. I want to have multiple UIViews inside the UIViewController.

I want to make a really simple iphone app: one screen with a single button... when the button is tapped a new screen appears. That's it.

I'd like to read an arbitrary PDF on my iPod Touch (or iPhone) with a reasonable font size. Some PDFs are already formatted with narrow columns and wide margins.

I began an iPhone project the other day with a silly development code name, and now I want to change the name of the project since its nearly finished. But I'm not sure how to do this with XCode, trying the obvious of changing the application's name in the pinfo, causes the signing process to go wrong (I think...) and my app won't laun...
