GameCenter

This property indicates if the local player is authenticated with Game Center. You should not call other GameCenter related methods if this property is false, so it is a good practice to bind the property to other elements dealing with GameCenter, e.g. hide a button if the player is not authenticated:

 SimpleButton {
   text: "Highscores"

   visible: gameCenter.authenticated
   onClicked: gameCenter.showLeaderboard();
 }

This handler is called after an achievement was reported to GameCenter. The success property indicates if it was successful. In normal you however don't need to take further actions in case of a failure because the plugin keeps track of achievements and synchronizes them as soon as it is possible again.

Note: The corresponding handler is onAchievementReported.

See also reportAchievement().
