title: How to use UIVisualEffectView to Blur Image?
body: <p>Could someone give a small example of applying the blur to an image?  I've been trying to figure out the code for a while now :( still new at obj c!</p>
  
  <blockquote>
    <p>The <code>UIVisualEffectView</code> provides a simple abstraction over complex
    visual effects. Depending on the desired effect, the results may
    affect content layered behind the view or content added to the view’s
    contentView.</p>
    
    <p>Apply a <code>UIVisualEffectView</code> to an existing view to apply a blur or
    vibrancy effect to the exiting view. After you add the
    UIVisualEffectView to the view hierarchy, add any subviews to the
    contentView of the <code>UIVisualEffectView</code>. Do not add subviews directly to
    the <code>UIVisualEffectView</code> itself.</p>
