title: Calling a function once after tableview.reloadData
body: <p>Every time I reload my table by calling </p>
  
  <pre><code>tableview.reloadData()
  </code></pre>
  
  <p>I want to call a specification function like </p>
  
  <pre><code>myFunction()
  </code></pre>
  
  <p>I was wondering, instead of stacking these two function next one after another everywhere in my code like </p>
  
  <pre><code>tableview.reloadData()
  myFunction()
  </code></pre>
  
  <p>Is there a smart and clean way of calling myFunction every time tableview reloads?</p>
