title: Show splash screen only once IOS
body: <p>I understand, Its a HIG violation to play around with the default launch icons and splash screens, but I have requirement such that, I need to display the splash screen only for the first time, Is it possible to implement it ?
  One simple solution, I can think of is : displaying  as an imageView on top of UIwindow and then removing it based on a timer. Am looking for other options.</p>
