如何在iOS 7中加载默认排行榜

Question

目标:当本地用户点击ios 7设备上应用程序中的排行榜按钮时，向其显示默认排行榜。

[[GKLocalPlayer localPlayer] loadDefaultLeaderboardIdentifierWithCompletionHandler:(void(^)(NSString *leaderboardIdentifier, NSError *error)) {

    //Use the leaderboard identifier.
    MyLeaderBoardID
}]

Answer 1

将UIButton链接到以下方法以显示默认排行榜：

- (void) presentLeaderboards
{
    GKGameCenterViewController* gameCenterController = [[GKGameCenterViewController alloc] init];
    gameCenterController.viewState = GKGameCenterViewControllerStateLeaderboards;
    gameCenterController.gameCenterDelegate = self;
    [self presentViewController:gameCenterController animated:YES completion:nil];
}
