title: How to set cursor position for UITextView on user input?
body: <p><em>I am looking for a simple answer for this problem...</em></p>
  <p>I have a <code>UITextView</code> in which the user can start typing and click on DONE and resign the keyboard.</p>
  <p>When the wants to edit it again, I want the cursor (the blinking line) to be at the first position of the <code>textView</code>, not at the end of textView. <strong>(act like a placeholder)</strong></p>
  <p>I tried <code>setSelectedRange</code> with <code>NSMakeRange(0,0)</code> on <code>textViewDidBeginEditing</code>, but it does not work.</p>
  <h3>More Info:</h3>
  <p>It can be seen that.. when the user taps on the <code>textView</code> the <code>cursor</code> comes up at the position where the user taps on the <code>textView</code>.</p>
  <p>I want it to always blink at starting position when <code>textViewDidBeginEditing</code>.</p>
