title: NSLocalizedString only retrieves the key, not the value in Localizable.strings (IOS)
body: <p>I've made a strings file named "Localizable.strings" and added two languages to it, like so:</p>
  
  <pre><code>"CONNECTIONERROR" = "Check that you have a working internet connection.";
  "CONNECTIONERRORTITLE" = "Network error";
  </code></pre>
  
  <p>I have also converted the files to Unicode UTF-8
  However, when I create a UIAlertView like this:</p>
  
  <pre><code> UIAlertView *myAlert = [[UIAlertView alloc]
   initWithTitle:NSLocalizedString(@"CONNECTIONERRORITLE",nil)
   message:NSLocalizedString(@"CONNECTIONERROR",nil)                    
   delegate:self
   cancelButtonTitle:@"Ok"
   otherButtonTitles:nil];
  </code></pre>
  
  <p>the alert view only shows the key text, not the value. It works if I, for example, set a UITextviews text to NSLocalizedString(@"CONNECTIONERROR",nil), but the alert view only displays the key. Anyone know what's wrong?</p>
