Question

I was trying to create a tab bar based application from scratch but I’m having some issues. Basically I have my AppDelegate.h, AppDelegate.m and a MainView.xib. In the the .h file I have:

@interface AppDelegate : UIResponder <UIApplicationDelegate, UITabBarControllerDelegate>

@property (strong, nonatomic) UIWindow *window;
@property (strong, nonatomic) IBOutlet UITabBarController *tabBarController;

@end

In My .m I have:

@synthesize window = _window;
@synthesize tabBarController = _tabBarController;

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

    // Override point for customization after application launch.
    self.window.rootViewController = self.tabBarController;
    [self.window makeKeyAndVisible];
    return YES;
}

And in my xib file I have my files owner as a class of Appdelegate and I have my outlet from there hooked up with a Tab Bar Controller. The problem is that my controller is returning null and thus isn’t being set as the rootViewController. What step/idea am I missing in setting up my app? Thanks in advance!

EDIT FIXED: Since I was starting from a empty application I didn’t have ‘Main nib file base name’ set, so I just had to set it to the nib I was trying to load.
