title: Swift tableView bottom loading indicator
body: <p>I am currently struggling with implementing a bottom loading indicator for my app, exactly like Instagram and Facebook has. Simply I want to show a loading indicator at the bottom (on reverse drag) just like a normal table view loading. </p>
  
  <p>Here is the code that I have for the regular table view update:</p>
  
  <pre><code>var refreshControl: UIRefreshControl!
  
  //In viewDidLoad
  
  refreshControl = UIRefreshControl()
  refreshControl.addTarget(self, action: "Refresh:", forControlEvents: UIControlEvents.ValueChanged)
  tableView.addSubview(refreshControl)
  </code></pre>
  
  <p>In my func Refresh() I simply just fetch the data, and controls the activity indicator from there. However, how would I approach this, if I wanted to enable this in the bottom of my tableView?</p>
  
  <p>Help is much appreciated.</p>
