Handling UITextView touch event when touch up a word in it
<p>I have a <code>UITextView</code> which display a paragraph. For example:</p>

<pre><code>self.myTextView.text = @"This is a sample paragraph"
</code></pre>

<p>What I want to do now is when I touch up a word in this paragraph, such as "This", a function will be call: <code>[self aFunction:@"This"]</code></p>

<p>Are there any ideas for handling this event and the way to get the parameter, which is the word  user touched. Maybe, I need other way to display the paragraph, not by a <code>UITextView</code>.</p>
