title: Update tableView height on basis of number of sections
body: <p>I want to adjust my <em>tableview height</em> according to the number of sections using auto layout.</p>
  
  <p>Number of sections may <code>vary.Data</code> for section one and two is not fixed.
  Each section is having different data.</p>
  
  <p>Beneath the TableView their are other components (<code>UILabel</code>, <code>UIButton</code>) and they are fixed but adjust their position if <code>tableView</code> shrinks or expands (TableView max height = height of view).</p>
  
  <p>I don't want to give a static height.</p>
  
  <p><code>UITableView</code> constraint's height will be changed in <code>viewDidLoad</code>?</p>
  
  <p>How to implement it?</p>
