title: Why is -[UISearchBar showsScopeBar] ignored?
body: <p>As long as <code>-[UISearchBar scopeButtonTitles]</code> is not <code>nil</code>, the search bar displays its scope bar no matter whether I set <code>showsScopeBar</code> to <code>YES</code> or <code>NO</code>. Is this a bug or am I doing something wrong?</p>
