title: UISearchBar : searchBarSearchButtonClicked delegate is not called
body: <p>In my case, I would restrict search bar text up to 50 characters. So I used <strong>shouldChangeTextInRange</strong></p>
  
  <pre><code>- (BOOL)searchBar:(UISearchBar *)searchBar shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text {
  return [searchBar.text length] + [text length] - range.length &gt;= 50);
  }
  </code></pre>
  
  <p>But <strong>searchBarSearchButtonClicked</strong> is not called when search bar text more than 50 characters.</p>
  
  <p>How do I handle this?</p>
