iOS: Is is possible to make a UINavigationBar taller and "push" the other views down the screen?

Question

Is there a way to make the "content" area of an iPhone app aware of a larger navigation bar?

Similar to these questions:

• iOS: Adding a fixed image just below the navigation bar
• iOS: Positioning navigation bar buttons within custom navigation bar

I've managed to use the 1st questions sample code to add a category on UINavigationBar and change its height, and added a subview where I need it, but I can't see a way to cause the UITableView (or indeed any content views) to take its height into consideration:

(The colors are only to make the different views distinguishable)

Answer 1

The accepted answer to the first question sets the nav bar's frame in -layoutSubviews, which is anywhere from "ewwwww" to outright wrong depending on the assumptions made by other layout code.

Instead, override -sizeThatFits: to return a more appropriate size.
