title: Forcing iPhone6 to take 3x or Retina4 2x graphics
body: <p>Is there a way by which we can programmatically enforce iPhone 6 device to take either Retina4-2x or 3x graphics instead of 2x graphics from asset catalog? Presently, I noticed that iPhone 6 is picking 2x graphics, instead of Retina4-2x.</p>
