Xcode 4 for Dummies: Why are Storyboard Settings not Being Applied When the App Runs?

SOLUTION

Make sure in the plist that the storyboard name is listed as the main storyboard file name.

I have a Storyboard with a UINavigationViewController that's connected to a NavigationViewController class and it's set as the UIWindow rootViewController. When the app runs (in the Simulator (5.1)) I get a blank black screen with the blue-ish navigation bar on the top.

The first problem is that in the storyboard, I set the navigation bar to black. I also set the status bar to translucent black. Neither styles are being honored when the app runs.

And the second problem is that the navigation controller's view is empty even though in the storyboard it has a relationship to a UITableViewController.

How can I fix both of these issues. I just started using Xcode again and had been using 4.0 before so the storyboards are throwing me off...

UPDATE

Here's the code as requested. Obviously I can't post the storyboard (can I?).

AppDelegate:

#import "AppDelegate.h"

@implementation AppDelegate

@synthesize window = _window;
@synthesize navigationController;

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

navigationController = [[NavigationViewController alloc] init];

    self.window.rootViewController = navigationController;
[self.window makeKeyAndVisible];

    return YES;
}

- (void)applicationWillResignActive:(UIApplication *)application {
}

- (void)applicationDidEnterBackground:(UIApplication *)application {
}

- (void)applicationWillEnterForeground:(UIApplication *)application {
}

- (void)applicationDidBecomeActive:(UIApplication *)application {
}

- (void)applicationWillTerminate:(UIApplication *)application {
}

@end

NavigationViewController:

#import "NavigationViewController.h"

@interface NavigationViewController ()
@end

@implementation NavigationViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];

if (self) {
    }

    return self;
}

- (void)viewDidLoad {
    [super viewDidLoad];
}

- (void)viewDidUnload {
    [super viewDidUnload];
}

 - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}

@end

The problem is that you are setting as the root controller a completely blank root controller, not the one from the story board. What you want to do is to delete that part of the code, and simply on the storyboard click the thing that says "is initial view controller"

When using storyboards you usually dont have to modify the appdelegate, because xcode sets which is the initial view that will appear and all of that based solely on how you set the storyboard. You can check this in the plist where it says which storyboard will be used as the main one.

If you want to load your navigation controller like that then you can do something like that you would have to get the viewcontroller from the storyboard itself and present it.

instantiateViewControllerWithIdentifier

but there is no need for that when using storyboards as it automatically loads whichever is set as the initial one (which can be seen as the viewcontroller with the arrow pointing at it)

Your app delegate method should look like this

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    return YES;
}
