title: Game Center custom leaderboard - Do I really need to make 2 calls to get a player's alias?
body: <p>I'm using game center to set up a custom leaderboard, when it comes to retrieving the data for my UITableView, I only get the playerID property for each entry, but not a much more useful alias property which I want to use to display who got each score. </p>
  
  <p>I don't understand why Apple has done it like this, surely a score on a scoreboard is meaningless without the name of the player that got it?</p>
  
  <p>Anyway, it seems the only way I can get the name of the player is to use the loadPlayersForIdentifiers:withCompletionHandler: method of the GKPlayer class. This seems like an unnecessary step - can anyone confirm whether this is what needs to be done just to get the player's alias?</p>
