title: UIImage Caching
body: <p>Its is well documented that UIImage imageNamed caches the images. And the trend with the newer version of iOS is to use Asset Files to simplify all the @2x and @3x images for all devices. </p>
  
  <p>But to avoid caching the images and to make best use of memory with images, so far I would use methods like imageWithData. But these methods don't work with Asset files that has been my understanding so far. Cause I could not find methods like pathForResource on the bundle working properly for Asset images. Is this a drawback on iOS or is there a nice workaround or is it just plain n00b ness on my behalf?</p>
  
  <p>On one of my projects I have noticed a large memory consumption only because some image used on some startup screen or so still being cached courtesy imageNamed:</p>
  
  <p>How can one work around this i.e continue using the simplicity and ease of Asset set Images and yet avoid caching using imageNamed:</p>
  
  <p>Thanks</p>
