title: "Please wait" dialog in iOS8
body: <p>I used to have a <strong>"Please wait"</strong> dialog in my app for long time. It was quite simple thing using <code>UIActivityIndicatorView</code> and adding it to <code>UIAlertView</code>. </p>
  
  <p>However iOS8 introduced <code>UIAlertController</code>. Is it possible to add anything to it to have similiar effect? Is there another way of doing such thing with iOS8?</p>
  
  <p>I have searched a lot of sites and still have no idea how it can be done with the new API.</p>
  
  <p>I would appreciate any answers - links to libs, tutorials etc., which could be helpful. </p>
  
  <p>Regards,</p>
