【问题描述】：

每次运行我的应用程序时，我都会在调试日志中收到该错误。我单击查找游戏，它带我进入主屏幕，由于此错误，键盘无法工作，当我点击后退按钮时，它只是弹出视图控制器（再次由于此错误）。我不知道如何解决它，所以任何帮助将不胜感激。谢谢。

// A peer-to-peer match has been found, the game should start
- (void)turnBasedMatchmakerViewController: (GKTurnBasedMatchmakerViewController *)viewController didFindMatch:(GKTurnBasedMatch *)match
{

// Display default view  [presentingViewController dismissViewControllerAnimated:YES completion:nil];

[presentingViewController dismissViewControllerAnimated:YES completion:^{
    // Present next controller here
[presentingViewController performSegueWithIdentifier:@"GamePlayScene" sender:match];
}];

// Removing line below fixes  Warning: Attempt to dismiss from view controller <GameNavigationController: 0x78f4f820> while a presentation or dismiss is in progress!

// [self dismissModalViewController];

【解决方案1】：

GameKit 文档指出您的 didFindMatch 方法应该关闭视图控制器并对匹配对象执行所需的操作。

你的方法应该是这样的。

- (void)turnBasedMatchmakerViewController: (GKTurnBasedMatchmakerViewController *)viewController didFindMatch:(GKTurnBasedMatch *)match {
    // Dismiss the view controller
    [viewController dismissViewControllerAnimated:YES completion:nil];
    // Perform your logic
}

来自GameKit documentation：

您的游戏应该关闭视图控制器并使用匹配对象向玩家显示比赛的当前状态。

还是同样的问题。 // Dismiss the view controller [viewController dismissViewControllerAnimated:YES completion:nil]; // Present next controller here [presentingViewController performSegueWithIdentifier:@"GamePlayScene" sender:match];
你的presentingViewController 是什么？
@interface GameKitHelper: NSObject<GKTurnBasedMatchmakerViewControllerDelegate, GKLocalPlayerListener> { UIViewController *presentingViewController; } --- Break --- - (void)findMatchWithMinPlayers:(int)minPlayers maxPlayers:(int)maxPlayers viewController:(UIViewController *)viewController { presentingViewController = viewController;" -Break // This line of code breaks the back button on game screen [presentingViewController presentViewController:mmvc animated:YES completion:nil]; } 我的实际视图控制器都没有称为presentingViewController。
