title: How can I make the footerview always stay at the bottom in UITableViewController?
body: <p>I am using a <code>UITableviewcontroller</code> and I want the <strong>footer view</strong> to always stay at the <strong>bottom</strong> of the screen. However, the <code>y</code> position of the <strong>footer view</strong> is changing as per the <code>height</code> of the <code>tableviewcell</code>. How can I always make it stick to the bottom of the screen?</p>
