title: UITextView adding text to new line
body: <p>I would like to add new lines of text to my UITextView for my iPhone app. Basically my textview starts with a single line, and as app advances, new lines are added. However I can add only to the end or beginning of the existing text. How can I make such an entry into a new line. Can I manually send \n to the textview.text at a calculated range/location.</p>
  
  <p>E.g. of what I mean.
  line 1: This is first line of text. This is second 
  line 2: line of text. ---</p>
  
  <p>I want:
  line 1: This is first line of text.
  line 2: This is second line of text.</p>
  
  <p>Thanks!</p>
