title: detecting URL and format it in UITextField
body: <p>I would like to be able to format a URL in my UITextField nicely. So say the text of the UITextField is </p>
  
  <pre><code>textField.text = @"Hi this is a page for my website http://www.mywebsite.com";
  </code></pre>
  
  <p>I would like it to automatically underline this mark it as a hyperlink and when a user taps on the link it opens up the site. This is similar to any twitter client that you have out there (tweetdeck, tweetbot, etc). How do I do this the easy way?</p>
