Display a Splash Screen Before Loading the Root Navigation Controller - iPhone

I am new bee in iPhone. I have implmented using some tutorials, a Splash Screen before loading the UIViewController. Now i want to implement a NavigationController in my application and want to display a Splash Screen before it. Since I am new in Iphone so i did not get any tutotrials or guides to make a Splash Screen before loading a Root Navigation Controller.

I have seen many methods in which they over write the Default.png file and so on. I dont want to implement that one. I want a sperate UIView to have my custom Images and text in it and display that UI View as a Splash Screen

can anybody Guide me please.

Thanks in advance

Use "self.window" to display the splash image first. If u simply write "window", the image will not be displayed and animated in the first view, since the image can't be directly linked to the window in that case. Write the following code in appdelegate.m

 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions         
    {
           self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
        // Override point for customization after application launch.

        MasterViewController *masterViewController = [[MasterViewController alloc] initWithNibName:@"MasterViewController" bundle:nil];
        self.navigationController = [[UINavigationController alloc] initWithRootViewController:masterViewController];
        self.window.rootViewController = self.navigationController;
        [self.window makeKeyAndVisible];

        UIImageView *imgv = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"themes.png"]];
        imgv.userInteractionEnabled = YES;
        [self.navigationController.view addSubview:imgv];
        //[imgv release]; If you don't use ARC, uncomment this.

        [self performSelector:@selector(removeSplash:) withObject:imgv afterDelay:3.0];
        [self.window addSubview:self.navigationController.view];

        return YES;
    }

- (void)removeSplash:(UIImageView *)imageView 
  {
       [imageView removeFromSuperview];
  }
