title: Cocoa-Touch: How to set the interpolation quality to be used by a UIImageView?
body: <p>I have a <code>UIImageView</code> showing a image that is larger than it's frame.<br>
  It's set to rescale the image to fit it's frame. But, the image is scaled with a low quality filter.</p>
  
  <p>I've <a href="http://vocaro.com/trevor/blog/2009/10/12/resize-a-uiimage-the-right-way/" rel="nofollow noreferrer">read here</a> that this is caused by it using a low interpolation quality.</p>
  
  <p>How can I get it's context to <code>CGContextSetInterpolationQuality</code> to <code>kCGInterpolationHigh</code>?</p>
