iPad Landscape Mode - How To Add Two Splash Screen

I have successfully finished my app after months of coding. Now I'm trying to add the initial Splash Screen images to my app. How do i proceed? I have two images: one is the company logo and the other is the app logo (these splash screens are to hide the loading time). I have looked every where for an possible answer, but ended up with no solution. When i name a single pic Default-Landscape.png and run the Ipad App - The image is showing until the main view controller loads up, but I want the first image to be displayed for 1 second and fade out to the second image which will also be displayed for 1 second after which the main view controller appears(the original application page).

I have checked various answers, but none seems to work - Xcode 4 and iPad2 splash screen issue Setting splash images for portrait and landscape mode - IPad etc..

Here is my code for the same - AppDelegate.h

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{

    NSArray *docDir=NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *docPath=[docDir objectAtIndex:0];
    databasePath=[docPath stringByAppendingPathComponent:@"something.sqlite"];
    //databasePath1=[docPath stringByAppendingPathComponent:@"something.sqlite"];

    NSString *bundlePath=[[NSBundle mainBundle]pathForResource:@"something" ofType:@"sqlite"];
    NSFileManager *mngr=[NSFileManager defaultManager];
    if ([mngr fileExistsAtPath:databasePath]) {
        NSLog(@"File Exists");
    }
    else
    {    
        [mngr copyItemAtPath:bundlePath toPath:databasePath error:NULL];
        NSLog(@"File Created");
    }

    self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
    // Override point for customization after application launch.
    self.viewController = [[[ViewController alloc] initWithNibName:@"ViewController" bundle:nil] autorelease];
    self.window.rootViewController = self.viewController;
    [self.window makeKeyAndVisible];
    return YES;
}

How should I proceed now? Should I create a new class like (splashScreen 1 and splashScreen 2) with uiImageView and change the didFinishLaunchingWithOptions method? Any help would be greatly appreciated.

Appdelegate.h

#import <UIKit/UIKit.h>
#import "sqlite3.h"
#import "FBInteract.h"
#import "splashScreen1.h"


sqlite3 *dbHandler;
NSString *databasePath;
@class ViewController;

@interface AppDelegate : UIResponder <UIApplicationDelegate> {

    UIWindow *window;
    UINavigationController *naviObj;
}

@property (strong, nonatomic) UIWindow *window;

@property (strong, nonatomic) ViewController *viewController;

@property (strong, nonatomic) UINavigationController *naviObj;

@end

Appdelegate.m

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

    splashScreen1 *splashScreen1PageObj=[[splashScreen1 alloc]init];

    self.naviObj = [[UINavigationController alloc]initWithRootViewController:splashScreen1PageObj];

    self.window.rootViewController = self.naviObj; 

    [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:NO];

    [self.window makeKeyAndVisible];

    return YES;

}

splashScreen1.h and splashScreen2.h

#import <UIKit/UIKit.h>
#import "splashScreen2.h"

@interface splashScreen1 : UIViewController

{
    IBOutlet UIImageView *imgObjSplashImage; //  IBOutlet UIImageView *objSplashImage; - in splashScreen2.h

}

-(void)hideSplash;

-(void)navigationToMain;

-(void)showSplash;

@end

splashScreen1.m and splashScreen2.m

- (void)viewDidLoad
{

    // Do any additional setup after loading the view from its nib.

    [NSTimer scheduledTimerWithTimeInterval:1.2 target:self selector:@selector(showSplash) userInfo:nil repeats:NO];

    self.navigationController.navigationBarHidden=YES;

    [imgObjSplashImage setAlpha:0]; //objSplashImage instead of imgObjSplashImage in splashScreen2

    [super viewDidLoad];

}

-(void)showSplash{


    [UIImageView beginAnimations:nil context:NULL];

    [UIImageView setAnimationDuration:1.2];

    [imgObjSplashImage setAlpha:1]; //objSplashImage instead of imgObjSplashImage in splashScreen2

    [UIImageView commitAnimations];

    [NSTimer scheduledTimerWithTimeInterval:2.4 target:self selector:@selector(hideSplash) userInfo:nil repeats:NO];

}

    -(void)hideSplash{


        [UIImageView beginAnimations:nil context:NULL];

        [UIImageView setAnimationDuration:1.4];

        [imgObjSplashImage setAlpha:0]; //objSplashImage instead of imgObjSplashImage in splashScreen2

        [UIImageView commitAnimations];

        [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(navigationToMain) userInfo:nil repeats:NO];

    }

    #pragma mark
#pragma mark - Navigation Coding

-(void)navigationToMain {

    //[self dismissModalViewControllerAnimated:YES];

    [self dismissViewControllerAnimated:NO completion:Nil];

    ViewController *ViewControllerPageObj=[[ViewController alloc]init];

    [self.navigationController pushViewController:ViewControllerPageObj animated:NO];

    [ViewControllerPageObj release];

    //[self presentViewController:ViewControllerPageObj animated:NO completion:Nil];

}

-(void)viewWillAppear:(BOOL)animated {

    self.navigationController.navigationBarHidden=YES;

}

The problem is ViewController(main ViewController) is not loading...I'm getting error saying "message sent to deallocated instance" in viewDidLoad part of ViewController.m

RootViewController -> splashScreen1 -> splashScreen2 is working fine(with all the animation fading in and out) but the final ViewController is not loading..

For this you definitely want another VC, lets call it StartViewController. Add there an imageView, block rotation and setTimer:

[NSTimer scheduledTimerWithTimeInterval:2.0 target:self selector:@selector(moveOnAndChangeVC:) userInfo:nil repeats:NO];

and if you develop NavigationControl app you should also change rootVC for example:

+(void)replaceRootVCWithVC:(id)vc {
    NSMutableArray *viewControllers = [NSMutableArray arrayWithArray:[[sharedAppDelegate navigationController] viewControllers]];
    if(![viewControllers isEmpty])
        [viewControllers replaceObjectAtIndex:0 withObject:vc];
    else
        [viewControllers addObject:vc];

    [[sharedAppDelegate navigationController] setViewControllers:viewControllers];
}

EDIT:

You should change in your appDelegate line with initializer:

self.viewController = [[[StartViewController alloc] initWithNibName:@"StartViewController" bundle:nil] autorelease];

This should call your VC as a rootVC.

Then in StartViewController.m you should recognize device (this is a iPad only app, right? not universal) and orientation:

+(NSString*)recognizeDeviceAndOrientation {

    NSMutableString * returnString;
    if([StartViewController deviceInterfaceOrientation] == UIInterfaceOrientationLandscapeLeft ||    [StartViewController deviceInterfaceOrientation] == UIInterfaceOrientationLandscapeRight) {
        returnString = @"Default-Landscape";
    } else {
        returnString = @"Default-Portrait";
    }

    if([UIScreen mainScreen].scale == 2.0)
        return [NSString stringWithFormat:@"%@%@",returnString,@"@2x"];;
    else
        return returnString;
}

+(UIInterfaceOrientation)deviceInterfaceOrientation {
    return [[UIApplication sharedApplication] statusBarOrientation];
}

This will return you a string with DefaultScreen name with proper orientation. If you handling only one orientation forget about it.

Then in viewDidLoad you add imageView:

- (void)viewDidLoad {
    [super viewDidLoad];    
    UIImageView *imageView = [[[UIImageView alloc] initWithImage:[StartViewController recognizeDeviceAndOrientation]] autorelease];
   [imageView setFrame:self.frame];
   [imageView setContentMode:UIViewContentModeScaleToFill];
   [self.view addSubview:imageView];

   [NSTimer scheduledTimerWithTimeInterval:2.0 target:self selector:@selector(moveOnAndChangeVC:) userInfo:nil repeats:NO];
}

This will call a timer and set imageView.

-(IBACtion)moveOnAndChangeVC:(id)sender {
   //if you using navigation app
   ViewController *vc = [[[ViewController alloc] initWithNibName:@"ViewController" bundle:nil] autorelease];
   [self.navigationController pushViewController:vc animated:NO];
}

This will work. And then if you want to get rid of "back button" just change a rootView Controller like i said in the beginning. Do it in your ViewController class.
