title: UIAlertController and UIAlertControllerStyleActionSheet customization
body: <p>I'm trying to create a custom <strong>UIAlertController</strong> with style <strong>UIAlertControllerStyleActionSheet</strong> (formerly UIActionSheet) and I'm encountering so much trouble to simply customize it. I want my UIAlertAction to <strong>contain an image on the left</strong> and <strong>decrease buttons size</strong>. </p>
  
  <p>I know it's feasable : </p>

  <p>(that's exactly what I'm seeking for)</p>
  
  <p>I searched for hours but I can't find any tut's on the internet that can help me to achieve that simple task. Plus, as UIActionSheet is deprecated since IOS 9, anytime I try to find a solution it's not usable anymore. Also, i read that UIAlertController is not intended to be subclassed... </p>
  
  <p>Does anyone know how to achieve that light customization of my alert? 
  Do I have to sublass a UIView to make my own alertsheet? </p>
