title: TableView with image background and blur effect - swift
body: <p>I have a little problem: I'd like to set an image to background in a TableViewController. I tried this:</p>
  
  <pre><code>class SquadreController: UITableViewController {
  
      override func viewDidLoad()
      {
          super.viewDidLoad()
  
          var sfondo = UIImage(named: "sfondo")
          self.view.backgroundColor = UIColor(patternImage: sfondo!)
  
      }
  </code></pre>
  
  <p>Then I give the blur effect to the view, like this:</p>
  
  <pre><code>let blur = UIBlurEffect(style: UIBlurEffectStyle.Light)
  let blurView = UIVisualEffectView(effect: blur)
  blurView.frame = self.view.bounds
  view.addSubview(blurView)
  </code></pre>
  
  <p>But there is a big problem. I'm working in a TableView and the TableView, TableCell, NavigationItem, etc. have all disappeared after I apply the blur. Can someone help me?</p>
  
  <p>Thanks a lot!</p>
