title: textFieldShouldReturn method of UITextview
body: <p>Needing to present user a multiline text field for comment entry, I am using a UITextView instead of a UITextField. I would like to use <code>textFieldShouldReturn</code> on my UITextView to send the data to server. How might I do that? Based on my readings so far, the method is only applicable to UITextField. So what is the equivalent for UITextView?</p>
