title: Easy way to check for continents using NSLocale, NSLocaleCountryCode?
body: <p>Is there a way to check if the user's current country is in Europe, Asia or Africa?</p>
  
  <p>I working on an app that does something different for the UK and the US. I want to extend that logic so if the user's locale is set to a country in Europe, then I default to what I do for the UK. If it's outside Europe, UK, then I default to what I do for the US.</p>
  
  <p>This is what I do at the moment.</p>
  
  <pre><code>NSString *countryCode = [[NSLocale currentLocale] objectForKey: NSLocaleCountryCode];
  if ([countryCode isEqualToString:@"UK"]) {
      NSString *startString = @"£ ";
  }
  if ([countryCode isEqualToString:@"US"]) {
      NSString *startString = @"$ ";
  }
  </code></pre>
  
  <p>Is there a simple way to check for continents?</p>
