objective-c - 游戏中心排行榜中的完成按钮不起作用

Question

当我在排行榜 View 中按下完成按钮时，它什么也没做，排行榜仍然可见。

代码如下:

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

您必须添加关闭 View Controller 的功能(委托(delegate))

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