Adding a UINavigationController as a subview of UIView

Using this code seems to work:

nav.view.frame = CGRectMake(nav.view.frame.origin.x, nav.view.frame.origin.y - 20,
                          nav.view.frame.size.width, nav.view.frame.size.height);

I did this before adding the navigation controller as a subview. Using the [UIApplication sharedApplication].statusBarFrame instead of the hard coded 20 would probably be a good idea too.

I'm not sure if it's the best way to do it though.

If you want a frame representing the available content area, then you should just use: [[UIScreen mainScreen] applicationFrame]. Of course, this restricts your top-level view controller so that it can only be top level. So still kind of dodgy, but less so.
