Add [self setUpSplash]; method in - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions method. And add following Three method in AppDelegate.m

-(void) setUpSplash {
    self.splashImgView = [[UIImageView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];
    [self.splashImgView setImage: [UIImage imageNamed:@"splash.png"]];
    [self.window addSubview: self.splashImgView];

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

- (void)closeSplashWithTimer:(NSTimer *)theTimer
{
    [UIView beginAnimations:@"ToggleViews" context:nil];
    [UIView setAnimationDuration:1.0];

    // Make the animatable changes.
    splashImgView.alpha = 0.0;
    self.mvNavigationController.view.alpha = 1.0;

    // Commit the changes and perform the animation.
    [UIView commitAnimations];

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

- (void)closeSplashWithTimerAgain:(NSTimer *)theTimer
{
    [self.splashImgView removeFromSuperview];
}
