title: How do custom URL schemes work with the `UILaunchImages` key in iOS7?
body: <p>The only Apple documentation I can find for <a href="https://developer.apple.com/library/ios/documentation/iPhone/Conceptual/iPhoneOSProgrammingGuide/App-RelatedResources/App-RelatedResources.html#//apple_ref/doc/uid/TP40007072-CH6-SW12" rel="nofollow">"Providing Launch Images for Custom URL Schemes"</a> only mentions a naming scheme based on the <code>UILaunchImageFile</code> key.  However, the <a href="https://developer.apple.com/library/ios/documentation/general/Reference/InfoPlistKeyReference/Articles/iPhoneOSKeys.html#//apple_ref/doc/uid/TP40009252-SW28" rel="nofollow">documentation for <code>UILaunchImages</code></a> says:</p>
  
  <blockquote>
    <p>If this key is present, iOS 7 uses it exclusively to obtain launch images. The system does not fall back to the older naming conventions used prior to iOS 7.</p>
  </blockquote>
  
  <p>As far as I can see, it doesn't say anything about how to tell iOS 7 to use a custom launch image for a custom URL scheme.</p>
