title: How to lose margin/padding in UITextView
body: <p>I have a <code>UITextView</code> in my iOS application, which displays a large amount of text.</p>
  <p>I am then paging this text by using the offset margin parameter of the <code>UITextView</code>.</p>
  <p>My problem is that the padding of the <code>UITextView</code> is confusing my calculations as it seems to be different depending on the font size and typeface that I use.</p>
  <p>Is it possible to remove the padding surrounding the content of the <code>UITextView</code>?</p>
