title: how to setup ios launchscreen.xib with LaunchImage in image.xcassets
body: <p>I am using Xcode 6.2 .  It now comes with a LaunchScreen.xib .  I also have a splash screen image in my image.xcassets.  </p>
  
  <p>Should I integrate the splash screen image into a imageview in the xib file?  I tried this, and it does not let me put that image file in the interface builder.</p>
  
  <p>How do I accomplish this?</p>
