title: iOS localization: plurals and NSNumberFormatter
body: <p>Is there a possibility to use NSNumberFormatter for NSNumber formatting together with plural rules in stringsdict?</p>
  
  <p>I need to have the next <em>with formatted numbers</em> (separate thousands). If I format the number using NSNumberFormatter - I receive NSString and I can't use plural rules anymore, because iOS can't understand whether phrase is for single or plural noun from NSString.</p>
  
  <p>"<em>1 Workout</em>" for single</p>
  
  <p>"<em>1,732,123 Workouts</em>" for plural</p>
  
  <pre><code>NSNumberFormatter* numberFormatter = ...;
  [NSString stringWithFormat:NSLocalizedString(@"%@ Workouts!", @"n Workout(s)"), [numberFormatter stringFromNumber:value]]
  </code></pre>
