title: IOS 8 NSLocationAlwaysUsageDescription custom translation
body: <p>I understood that I can have localized NSLocationAlwaysUsageDescription text using standard iOS localization mechanism.
  Since we are using our custom dynamic localisation mechanism I wonder if there is another way to translate that string.
  I thought of editing application info.plist file on app start, but it seems to be read only.</p>
  
  <p>Can I change this value from withing the app?</p>
