title: Fade out Launch Image on 4 Inch iPhone screen
body: <p>On launch, I am fading from my launch image to the application's interface. To achieve this, I am adding a <code>UIImageView</code> with "Default.png" and animating its alpha just before <code>makeKeyAndVisible</code>.</p>
  
  <p>Should Default.png always return the device-specific (or resolution-specific) version of the launch image? Or should I be checking the screen's bounds and scale to pick the right one for the retina vs non-retina and 3.5 vs 4 inch screens?</p>
  
  <p>I expected Default.png to behave much like other image resources - use the @2x version when supported (and the -568h version on the iPhone 5). But my experimentation in the simulator leads me to believe otherwise. Running the 4 inch simulator, the 3.5 inch image is used. This results in a splash image that does not extend to the bottom of the screen. The screenshot below shows the transition mid-animation.</p>

  <p>Unfortunately I don't have each device so was unable to confirm if this is just a quirk of the simulator.</p>
  
  <p>In short, I want to be sure that the retina image is used on retina devices, and the 4 inch image is used on 4 inch devices.</p>
