title: Automatically resizing UIButton height based on title - AutoLayout ON
body: <p>Basically the title explains the problem. Working with XCode, I have this button and I populate its title with different text sources (some are long texts some are short). I just want that the button resizes dynamically with the content using Autolayout.</p>
  
  <p>Things not working:</p>
  
  <ul>
  <li><code>sizeToFit</code>; </li>
  <li>Setting a height constraint of >= x;</li>
  <li>setting the button's frame height = titleLabel height.</li>
  </ul>
  
  <p>Nobody seems to know over the internet and I wonder how could it be possible? I think is one of the MOST COMMON FEATURES for a button.</p>
  
  <p>Someone knows a way to help me? Am I doing something wrong with this idea? Is there some other way to achieve this?</p>
  
  <p>Thank you to anyone who will answer. Really.</p>
