title: Gaussian Blur Over Image - iOS 8
body: <p>I have a moving background image and I want to blur the bottom part of it out. I <em>would</em> do it with just photoshop but since the image moves, it wouldn't work very well.</p>
  
  <p>Here is what I mean (look at the bottom of the image) :</p>
  
  <p><img src="https://i.stack.imgur.com/QjCQR.png" alt="http://i.imgur.com/OT3vpeQ.png"></p>
  
  <p>So basically like the effect the dock has on the iPhone. I'm using iOS 8 but not Swift.</p>
