title: UITextView insert text in the textview text
body: <p>I want to have  to occasionally insert text into the UITextView text object. For example, if the user presses the "New Paragraph" button I would like to insert a double newline instead of just the standard single newline.</p>
  
  <p>How can I go about such? Do i have to read the string from UITextView, mutate it, and write it back? Then how would I know where the pointer was?</p>
  
  <p>Thanks</p>
