title: iPhone how to get UITextField's text while typing?
body: <p>I'm trying to show changes made to a <code>UITextField</code> on a separate <code>UILabel</code>. Is there  a way to capture full text of the <code>UITextField</code> after each character the user types in? Currently I'm using this method, but it does not capture the last character that the user has entered. </p>
  
  <p>I know that <code>UITextView</code> has "didChange" method, but I could not find that method for a <code>UITextField</code>. </p>
  
  <pre><code>//does not capture the last character
  
  -(BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string
  {
  
          [self updateTextLabelsWithText: textField.text];
  
      return YES;
  }
  </code></pre>
  
  <p><strong>How can I take text out of UITextField after each character entered?</strong></p>
  
  <p>Thank you!</p>
