title: No achievement notification banners show up in iOS 7
body: <p>Hoping someone can confirm or refute the fact that it appears that achievements don't show when they are achieved. When run on an iOS 6 device the achievement shows up but when run on the iOS 7 it doesn't show up.</p>
  
  <p>Using <code>showsCompletionBanner</code> set to <code>YES</code>. <a href="https://developer.apple.com/library/ios/documentation/GameKit/Reference/GKAchievement_Ref/Reference/Reference.html#//apple_ref/occ/instp/GKAchievement/showsCompletionBanner" rel="nofollow">https://developer.apple.com/library/ios/documentation/GameKit/Reference/GKAchievement_Ref/Reference/Reference.html#//apple_ref/occ/instp/GKAchievement/showsCompletionBanner</a></p>
  
  <p>Atm I assume it's a bug in iOS7 and it will be fixed (who knows) so I'm not touching any code.</p>
