游戏中心领导板上的完成按钮不起作用

Question

当我在排行榜视图中按下完成按钮时，它不会执行任何操作并且排行榜仍然可见。

这是代码：

GKGameCenterViewController *gcViewController = [[GKGameCenterViewController alloc] init];

gcViewController.gameCenterDelegate = self;
[gcViewController setDelegate:self ];
if (shouldShowLeaderboard) {
    gcViewController.viewState = GKGameCenterViewControllerStateLeaderboards;
    gcViewController.leaderboardIdentifier = currentLeaderBoard;
}
else{
    gcViewController.viewState = GKGameCenterViewControllerStateAchievements;
}

[self presentViewController:gcViewController animated:YES completion:nil];**

Answer 1

你必须添加函数来关闭视图控制器（委托）

-(void)gameCenterViewControllerDidFinish:(GKGameCenterViewController *)gameCenterViewController{
[gameCenterViewController dismissViewControllerAnimated:YES completion:nil];

}

Answer 2

对我有用的是将GKGameCenterControllerDelegate添加到协议列表中。
