title: iOS: KILabel not responding to touch events
body: <p>I'm trying to use the <code>KILabel</code> subclass to handle things like hashtags and mentions in my project.  I've got the label rendering correctly and it appears to be responding to touch, but I cannot get it to register a tap handler successfully.  Here's the code in <code>viewDidLoad</code>:</p>
  
  <pre><code>    // Attach a block to be called when the user taps a user handle
      _testLabel.userHandleLinkTapHandler = ^(KILabel *label, NSString *string, NSRange range) {
          NSLog(@"User tapped %@", string);
      };
  
      // Attach a block to be called when the user taps a hashtag
      _testLabel.hashtagLinkTapHandler = ^(KILabel *label, NSString *string, NSRange range) {
          NSLog(@"Hashtag tapped %@", string);
      };
  
      // Attach a block to be called when the user taps a URL
      _testLabel.urlLinkTapHandler = ^(KILabel *label, NSString *string, NSRange range) {
          NSLog(@"URL tapped %@", string);
      };
  </code></pre>
  
  <p>And here is what it looks like in interface builder:</p>
  
  <p><a href="https://i.stack.imgur.com/jibcM.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/jibcM.png" alt="Showing the label hooked up properly"></a></p>
  
  <p><a href="https://i.stack.imgur.com/YMl8D.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/YMl8D.png" alt="And it&#39;s the proper class, too"></a></p>
  
  <p>For whatever reason, it's not recognizing any touch events.  I can physically see the interface showing a link being tapped, but I have nothing on the event side of things.  Can anyone help me out here?  I know its likely something simple but its not clear; I tried to follow the documentation as closely as I could though it isn't that extensive.</p>
  
  <p>Thanks in advance, getting this figured out would be a big get.</p>
