Multiple lines deletion in UITextView
<p>I am trying to adjust height of <code>UITextView</code> programmatically in <code>objective c</code> when the user types/deletes characters. It works perfectly for me as long as user does not delete multiple lines at a time. So, the main question is how could we detect multiple lines deletion in <code>UITextView</code> and get this number of lines (adjustment of height is easy afterwards).</p>
