title: Is there a way to limit the width of text in UITextView
body: <p>I have UITextView where I need to control where text start and end. </p>
  
  <p>This because I use bubble as background image for UITextView and I need to display the text inside the bubble image.</p>
  
  <p>So far,I have been able to control where text start using:</p>
  
  <pre><code>self.contentOffset = (CGPoint){.x = -10, .y = -10};
  </code></pre>
  
  <p>but I have no clue how to control where text end. Currently, by default  it uses all UITextView width.</p>
