Loading Tab Controller View in Window Based iPhone App

I am learning how to create apps with multiple views using the Window-based application template. I am trying to implement a tab bar but when my view loads, it is a blank. I realize it could be an issue between versions of iPhone SDK or Xcode. I am using the latest version of both (iOS 4.3 and Xcode 4.0).

My current code is as follows:

.h file:

@interface iBountyHunterAppDelegate : NSObject <UIApplicationDelegate> {
UIWindow *window;
UITabBarController *tabcontroller;

}

@property (nonatomic, retain) IBOutlet UIWindow *window;
@property (nonatomic, retain) IBOutlet UITabBarController *tabcontroller;

.m file:

@synthesize window;
@synthesize tabcontroller;
- (void)applicationDidFinishLaunching:(UIApplication *)application {    

// Override point for customization after app launch    
[window addSubview:tabcontroller.view];
[window makeKeyAndVisible];

}

In the sample code I downloaded, this worked fine. I can't figure out where the problem is and any suggestions would be greatly appreciated.

So I think I figured it out. Due to the lack of the UIWindow *window in the ApplicationDelegate.h @interface:

I had to reference [self.window addSubview:tabcontroller.view]; in my application didFinishLaunching method,

rather than just [window addSubview:tabcontroller.view];

Thanks for the assistance.

Have you added any view controllers to the tab bar controller? The tab bar controller doesn't have any content of its own, other than the tab bar itself. You need to add your own view controllers using -setViewControllers:animated:.
