Creating a new ViewController and xib for programmatic display (with addSubview)

Question

I am writing a library to be used by developers for the iPhone (similar to the way that OpenFeint is implemented) and I am trying to create a ViewController with an associated XIB so that I can instantiate it in my code with

SplashScreenViewController *splashScreenViewController = [[SplashScreenViewController alloc] init];
UIWindow *topApplicationWindow = [self getTopWindow];
[topApplicationWindow addSubview:splashScreenViewController.view];

However, while this works with simple controls (UIButtons, etc), nothing shows up with my SplashScreenViewController. SplashScreenViewController is very simple:

#import <UIKit/UIKit.h>
#import <Foundation/Foundation.h>


@interface SplashScreenView : UIViewController {
}

@end

and the implementation is empty. In my View XIB (SplashScreenView.xib), I have tried setting the File's Owner's class to SplashScreenViewController which didn't work, then I tried it the way I've seen it done in OpenFeint which is to add a View Controller in IB and make the main UIView a child of it and make it of class SplashScreenViewController instead. That also does not work (does not display).

I'm wondering if anyone has a good idea for what I might be missing, or if someone can recommend a walkthrough for creating new ViewControllers the way that I'm attempting to.

Thanks!

Try 2 things :

1. Call initWithNibName not just init. Maybe the OpenFeint you were talking about were overriding the init to call initWithNibName , that's why you don't see it.

2. Set SplashScreenViewController as your file owner, and connect his view outlet to your view in IB.

Hope it helps.

Instead of [splashScreenViewController alloc], try [SplashScreenViewController alloc]. I'm surprised you didn't get a compiler warning.
