title: iOS 7 style Blur view
body: <p>Does anybody know of any controls that will replicate the iOS7 style blur views. </p>
  
  <p>I'm assumming there can be some kind of UIView subclass that will replicate the behavior. </p>
  
  <p>I'm talking about these type views which blur the background extremely thickly so that they have pull effects from the background view. </p>
