title: Dynamic UITableViewCell not resizing according to the content
body: <p><a href="https://i.stack.imgur.com/zBDUc.png" rel="noreferrer"><img src="https://i.stack.imgur.com/zBDUc.png" alt="enter image description here"></a></p>
  
  <p>Senario A:
  If I set the label content in <code>cellForRowAtIndexPath</code>, the cell correctly get resized. </p>
  
  <p>Senario B: 
  If I change the text content in custom action in cell, the cell sized does not get changed.(I do call setNeedsLayout + layoutIfNeeded)</p>
  
  <p>How to fix this?</p>
  
  <p><strong>EDIT:</strong> </p>
  
  <p>1) I have set, 
  <code>myTableView.estimatedRowHeight = 71.0</code>
  <code>myTableView.rowHeight = UITableViewAutomaticDimension</code></p>
  
  <p>2) I have correctly added auto layout constraints.</p>
