I was attempting to clean up the implementation for a sub-panel on a navigation controller stack, so that the navigation bar could be customized in the XIB instead of doing it manually in the viewDidLoad method.
The original (working) setup had the XIB set up with the "File's Owner" class set to the view controller class, and then the view at the top level. This works fine.
In the "Interface Builder User Guide", p. 71, it describes the recommended way to build the XIBs for sub-panels ("additional navigation levels"). This approach leaves the "File's Owner" class as NSObject, but adds a UIViewController at the top level, and nests the view (and navigation item) underneath it. The UIViewController's view automatically gets connected to the contained view.
When I try to push the controller init'd with this new XIB, the app crashes because of a missing view:
SettingsViewController *controller = [[SettingsViewController alloc]
initWithNibName:@"SettingsView"
bundle:nil];
[self.navigationController pushViewController:controller animated:YES];

'NSInternalInconsistencyException', reason: '-[UIViewController
_loadViewFromNibNamed:bundle:] loaded the "SettingsTestView" nib but
the view outlet was not set.'
I've double checked everything, and tried building a clean XIB from scratch, but get the same result.
I looked through a number of the code sample projects, and NONE of them use the documented/recommended approach--they all use the File's Owner class and manually set up the navigation bar in viewDidLoad like I originally had it.
Is it possible to get it working the "recommended" way?
Thanks!
