title: How to get multiply blend mode on a plain UIView (not UIImage)
body: <p>I have an image in my iPad app and I basically want to place a color filter on top of it. For this I have a colored UIView that is masked to a certain shape that I put over the image. Since adjusting the alpha isn't giving me the desired effect I'd like to use blend modes instead.</p>
  
  <p>As far as I know you can only use blend modes on images and not plain views. The color of the view is dynamic so I can't just use a picture instead.</p>
  
  <p>I also tried rasterizing the view to an image, but that got all pixely and odd or something, but maybe I did something wrong.</p>
  
  <p>So, the basic question is: Is it possible to apply blend modes to views? Or should I take a completely different approach to reach the same goal?</p>
