title: Remove underline on UITextView link
body: <p>I'm trying the following to format links on UITextView:</p>
  
  <pre><code>self.textView.linkTextAttributes = @{NSForegroundColorAttributeName:[UIColor whiteColor], NSUnderlineStyleAttributeName:[NSNumber numberWithInteger:NSUnderlineStyleNone]};
  </code></pre>
  
  <p>The issue is that, the link color was changed to white, but it's still underlined.</p>
  
  <p>How can I solve it?</p>
  
  <p>This is my <code>attributedString</code>:</p>
