title: How do I send text to a UITextView?
body: <p>I'm new to iphone development. I'm a VB  programmer who is trying to convert a VB  application to an ipad app.</p>
  
  <p>I need some help with sending text to a UITextView.</p>
  
  <p>I want to first have a UIPickerView and then once the user hits a UIButton, a UITextView appears and the text is then generated by my source code code, line by line. The code would constantly be concatenating strings to the text.</p>
  
  <p>It would sort of go like this--</p>
  
  <ol>
  <li>User makes selections with UIPickerView.</li>
  <li>User then hits UIButton.</li>
  <li>UIPickerView is replaced on the screen with a UITextView.</li>
  <li>The code does stuff.</li>
  <li>The code adds the 1st line of text into the UITextView.</li>
  <li>The code does more stuff.</li>
  <li>The code then adds the 2nd line of text into the UITextView, retaining the 1st line that was already there.</li>
  </ol>
  
  <p>Steps 6 and 7 are repeated until the code is done.</p>
  
  <p>Does anyone know of any examples of this that I could look at? I am mostly interested in finding something like a youtube video, a webpage that explains the code or even a good book that covers this particular topic. I am finding that the sample codes that Apple has on this site goes over my head.</p>
  
  <p>In fact, I could probably benefit from a good book. But, I am looking for one that I would already know covers this particular topic, since it is so essential to the app that I am trying to build. </p>
