For your first solution, I don't think you can change the status bar in viewDidLoad. If you have two ViewControllers stacked on top of each other, and each one toggles the status bar differently, that method will only get called once for each. You really want to change the status bar in viewWillAppear so that it gets called each time the page is shown. I also don't think you can rely on preferredStatusBarStyle since I'm also not sure how often/when that gets called. This is how you want to do it:

- (void) viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];

    [self.navigationController.navigationBar setBarStyle:UIBarStyleDefault];
}
