title: Change UISearchBar cancel button text in iOS 8
body: <p>I'd like to change the text from &quot;Cancel&quot; to &quot;Done&quot; of the Cancel button inside the <code>UISearchBar</code> in iOS 8. I am using <code>UISearchController</code>. I've tried different approaches for iOS 6 and iOS 7 and they do not work. Has anybody done this?</p>
