title: Adding events/actions to an NSAttributedString
body: <p>I have an NSAttributedString below:</p>
  
  <pre><code>NSMutableAttributedString *myString = [[NSMutableAttributedString alloc] initWithString:@"This is my attributed text. Click on here to go to a new controller."];
  </code></pre>
  
  <p>I want to make the word here be an event passing to a new UIViewController. So I want the work "here" to be tapped and passed to a new view.</p>
  
  <p>How do I add a UIButton in there or a tap gesture to it? (Side note, the string can change and the "here" won't always be in the same place).</p>
