title: Dismiss iPhone number pad when a read only UITextView is touched
body: <p>In my simple iPhone app, I have a UITextField for entering text and UITextView for results. The UITextField uses a number pad since only numbers are allowed. The UITextView is read only but has user interaction enabled. The reason for this is that I want a user to be able to do copy and paste but not changing the result. It is well known that number pad doesn't have a "go" button. So I do <code>resignFirstResponder() in touchesBegan</code> and it works as long as I touch outside of the Text View Area. How do I dismiss the keyboard (number pad) even when the inside  of the UITextView is touched?</p>
