title: Access SDK-internal localisations like "Done", "Search" etc
body: <p>When I build a UI in  iOS I want to make it as familiar as possible. So imagine I make a non-standard button which should still have the caption "Done" (In multiple languages).</p>
  
  <p>I could now tediously try to figure out what the "Done button" is called in all those languages by changing the device language.</p>
  
  <p>I am wondering if there is a way to access such "internal translations" in my code.</p>
