title: Change the launch image of an app on every launch
body: <p>I want to change the launch image of my app each time I open it. I've searched on Google and I've found two approaches:</p>
  
  <ol>
  <li><p>Set my launch image name in the plist config file, and replace the image file each time.</p></li>
  <li><p>Delete the launch image property in the plist each time the app launches, display another imageview or uiview, and change the image of the imageview;</p></li>
  </ol>
  
  <p>The first way, some people said that Apple might reject the app or it may not be approved. Is this likely to be the case?</p>
  
  <p>The second way, it takes a long time after my app is configured and loaded and the app displays a black screen during the loading itself.</p>
