Question

GameCenter能够打开。但是，当在右上角按下“完成”按钮以解除GameCenter时，GameCenter仍然保持打开状态。如何关闭GameCenter？

以下是我的代码：

- (void) presentLeaderboards
{
    GKGameCenterViewController *leaderboardController = [[GKGameCenterViewController alloc] init];
    if (leaderboardController != nil)
    {
        leaderboardController.viewState = GKGameCenterViewControllerStateLeaderboards;
        UIViewController *vc = self.view.window.rootViewController;
        [vc presentViewController: leaderboardController animated: YES completion:nil];
    }
}

- (void)gameCenterViewControllerDidFinish:(GKGameCenterViewController *)viewController
{
    NSLog(@"Close");
    UIViewController *vc = self.view.window.rootViewController;
    [vc dismissViewControllerAnimated:YES completion:nil];
}

您永远不会为GKGameCenterViewController设置委托，因此永远不会调用您的gameCenterViewControllerDidFinish:方法。您应该通过一些调试自己找到它。
在dismissViewControllerAnimated上致电viewController。

您的代码应该更像：

- (void) presentLeaderboards
{
    GKGameCenterViewController *leaderboardController = [[GKGameCenterViewController alloc] init];
    if (leaderboardController != nil)
    {
        leaderboardController.gameCenterDelegate = self;
        leaderboardController.viewState = GKGameCenterViewControllerStateLeaderboards;
        UIViewController *vc = self.view.window.rootViewController;
        [vc presentViewController: leaderboardController animated: YES completion:nil];
    }
}

- (void)gameCenterViewControllerDidFinish:(GKGameCenterViewController *)viewController
{
    NSLog(@"Close");
    [viewController dismissViewControllerAnimated:YES completion:nil];
}

添加行：

leaderboardController.gameCenterDelegate = self;

可能会导致新的错误。如果是这样，您需要在@implementation行之前将.m添加到.m。

@interface MyViewControllerNameHere () <GKGameCenterControllerDelegate>

@end

如果您已有类扩展名，只需添加GKGameCenterControllerDelegate部分。
