title: Add a UIView over the top of UITableViewController in Swift
body: <p>I currently use a UITableViewController (PFQueryTableViewController), I would like to display a UIView over the top of the TableView.</p>
  <p>Ideally I'd like to do this in the storyboard, so I can easily add additional Labels/buttons to it. However, I can't seem to figure out how or if you can do it in storyboard. Is that right?</p>
  <p>I have tried it programmatically. I first created the variable at the top:</p>
  <p><code>var filterLabelView:UIView = UIView()</code></p>
  <p>I then added the following in <code>ViewDidLoad</code> :</p>
  <pre><code>filterLabelView.frame = CGRect(x: self.view.frame.width/2, y: self.view.frame.height/2, width: self.view.frame.width, height: 40)
  filterLabelView.center = CGPointMake(self.view.frame.size.width  / 2, self.view.frame.size.height / 2)
  filterLabelView.backgroundColor = UIColor.redColor()
  self.view.addSubview(filterLabelView) // See below
  </code></pre>
  <p>I also tried:</p>
  <pre><code>self.view.insertSubview(filterLabelView, aboveSubview: tableView)
  </code></pre>
  <p>This creates the red UIView, but it seems to be embedded to the tableview, as when I scroll up and down, the View moves with it.</p>
  <p><strong>What I want to create</strong></p>
  <p>Ideally, I want the view to sit at the bottom of the screen, and <strong>not</strong> move when the user scrolls. An example screenshot of how I want it look is below:</p>

  <p>I have read that the best way is to use a UIViewController with a UITableView inside it, but I'd rather not take that approach seeing how much my app is already built up.</p>
  <p>Can anyone help me create this look? Thanks in advance</p>
