title: How to set VoiceOver accessibility language for ALL elements at once?
body: <p>I can set the language for every single element through</p>
  
  <pre><code>@property(nonatomic, retain) NSString *accessibilityLanguage
  </code></pre>
  
  <p>and I remember that somewhere I came across a mention about a way to set the language for ALL elements at once. I think it was not a category on NSObject but an API that Apple provided. Can'T find it anymore.</p>
  
  <p>Is there an API or was it really just the NSObject category?</p>
