title: How to show search bar if UIButton is tapped
body: <p>I want to add a search bar inside a normal VC when you touch a button in that view. </p>
  
  <p>Is there a simple/elegant way of doing this? I presume I've to create it programmatically, but I don't know any nice solutions in which I can add animations to that transition instead of just showing and hiding them.</p>
