Tips and Best Practices
  1. During development, you should test your application to ensure that Game Center features are working correctly. Apple provides a sandbox environment to allow you to test your application separately from the live version or other live apps.
  2. Check for Game Center support. If Game Center is not supported on the current device, your game should be prepared to fall-back gracefully and proceed with Game Center features disabled, if it is able to do so.
  3. We've increased the data size for turn-based matches from 4 kb to 64 kb, so you can create more sophisticated gaming scenarios.
  4. The Game Center data associated with your app is uniquely associated with the app’s bundle identifier. Note that related apps such as “App Lite” and “App Pro” (with different bundle identifiers) each will have their own separate Game Center data.
  5. Game Center should only be used in games and entertainment apps. The Game Center feature set is designed for use in games and entertainment apps and intended to complement game functionality within an app.
