Question

Just trying to wrap my head around how different project types are built and I must be missing something.

I’m trying to start with a window based application and just add a Navigation Controller so I understand how the different components work with the Window and App delegate.

Here’s what I did:

• Created a Window based project
• In my app delegate.h I added
  @property (nonatomic, retain) IBOutlet UINavigationController *navigationController;

In my app delegate.m I added:

@synthesize navigationController;

(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Override point for customization after application launch.
    self.window.rootViewController = self.navigationController;
    [self.window makeKeyAndVisible];
    return YES;
}

• In the MainWindow.xib file I added a NavigationController below the
  Window
• Created a new UIViewController subclass (FirstView.h/m)
• Pointed the NavigationController’s root view controller to FirstView

Builds clean, when I launch I get an all white screen.

What am I missing?

Figured it out – I had to create a new Referencing outlet and connect the Navigation Controller to the App Delegate in the .xib.
