title: Modify an UITextView's frame to look like a speech bubble
body: <p>I don't know a lot about modifying the frame of an object I am using in a View and this is why I am coming to you with the following problem.How do you make your textview's frame look like a speech bubble</p>
  
  <p>Is it a way of modifying only the frame or do I need to create a custom textview class?</p>
  
  <p>I only want to add the little triangle on the left/right triangle to the frame </p>
  
  <p>The final result should be this!</p>
