title: Set blendmodes on UIImageViews like Photoshop
body: <p>I've been trying to apply blend modes to my UIImageViews to replicate a PSD mock up file (sorry can't provide). The PSD file has 3 layers, a base color with 60% normal blend, an image layer with 55% multiply blend and a gradient layer with 35% overlay.</p>
  
  <p>I've been trying several tutorials over the internet but still could not get the colors/image to be exactly the same.</p>
  
  <p>One thing I noticed is that the color of my iPhone is different from my Mac's screen.</p>
  
  <p>I found the documentation for Quartz 2D which I think is the right way to go, but I could not get any sample/tutorial about Using Blend Modes with Images.

  <p>Can anyone provide a good tutorial that does the same as the one in the documentation so I could atleast try to mix things up should nobody provide me a straight forward answer to my question.</p>
