title: View partial over navigationBar (Feedly app like)
body: <p>I have a UITableView that can be ordered with filters.
  Instead of using a modal view i wanted to just make an animation of a view comming from the left of the screen and partially covering my tableView.</p>
  
  <p>Here is an exemple of what i want my "filters view" to look like :</p>
  
  <p>Without the filter :</p>
  
  <p><img src="https://i.stack.imgur.com/qgg41.jpg" alt="Without the filter"></p>
  
  <p>With the filter :</p>
  
  <p><img src="https://i.stack.imgur.com/0DpAW.jpg" alt="With the filter"></p>
  
  <p>What could do the trick ?</p>
