title: iOS - UITextView multiline being disable after changing text
body: <p>I'm currently building a tableview and feeding information into the cell. In one of my prototype cell there was a <code>UITextView</code>. It looks ok if I build the project and display on simulator. However, if I change the text of <code>UITextView</code> programatically. The <code>UITextView</code> will disable multiline which only display one line string on centre and '...' at the end of the string.</p>
  
  <p>here is my code in method <code>tableView cellForRowAtIndexPath</code></p>
  
  <pre><code>cell = [tableView dequeueReusableCellWithIdentifier:@"identifier" forIndexPath:indexPath];    
  UITextView* label = (UITextView*)[cell viewWithTag:0];
  NSString* des = @"a long long long long string";
  [label setText:des];
  return cell;
  </code></pre>
