    [NSThread sleepForTimeInterval:5.0];  //for running splash screen more time
     UIActivityIndicatorView *spinner = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];

    spinner.center = CGPointMake(139.5, 75.5); // .5 so it doesn't blur

Try this...

UIImageView *splashView; // Declare in appDelegate.h

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    splashView = [[UIImageView alloc]initWithFrame:self.window.bounds];
    if (self.window.bounds.size.height > 480)
    {
        splashView.image = [UIImage imageNamed:@"Default-568h@2x.png"];
    }
    else
    {
        splashView.image = [UIImage imageNamed:@"Default.png"];
    }

    [self.window addSubview:splashView];

   // Add your spinner here.

    return YES;
}

Hope i helped.

The splash screen of your app is simply a png file that is static. You cannot add anything to it like a spinner or animation. What you can do however is once the splash screen finishes loading you can show a view that also has the same splash screen and then add the spinner to it programmatically or using interface builder. Basically from the user perspective they can't tell the difference.

I've used this technique before and it works quite nicely.

By the way, your sleep call will freeze your application momentarily. You are better off using an NSTimer so that the OS doesn't terminate your app for not responding.
