title: Link tap color for TTTAttributedLabel
body: <p>I am using a TTTAttributedLabel in my project. I have managed to change the default color and underlining for any link that I create by modifying the link attributes.</p>
  
  <pre><code>NSArray *pKeys = [[NSArray alloc] initWithObjects:(id)kCTForegroundColorAttributeName,
                        (id)kCTUnderlineStyleAttributeName
                       , nil];
  
  NSArray *pObjects = [[NSArray alloc] initWithObjects:pAlertColor,[NSNumber numberWithInt:
                                                                               kCTUnderlineStyleNone], nil];
  
  NSDictionary *pLinkAttributes = [[NSDictionary alloc] initWithObjects:pObjects
                                                                    forKeys:pKeys];
  
  self.alertMessage.linkAttributes = pLinkAttributes;
  self.alertMessage.activeLinkAttributes = pLinkAttributes;
  </code></pre>
  
  <p>However, I have noticed that when I tap on the link, it turns red momentarily as any other link does when tapped. I need to change this color. Any clues to how that might be done?</p>
