Show launch, splash screen for longer on iPhone / iPad / iPod

When you want to display your launch screen longer as normal you can do this by simply adding a sleep() in the AppDelegate implementation:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Time in seconds
    sleep(5);
    
    // Override point for customization after application launch.
    return YES;
}
