title: Callout on top of UITextView like in iMessage
body: <p>Is there an easy way without a custom view to achieve the Copy-More-Callyout on top of Message Bubbles like in iMessage?
  Whatever I searched for didn't lead me to a solution.</p>
  
  <p>My Bubble is based on a non-editable <code>UITextView</code>.</p>
