【中文标题】尝试在等待 GKTurnBasedMatchmakerViewController 延迟呈现完成的 ViewController 上呈现 GameViewController

【英文标题】：Attempt to present GameViewController on ViewController which is waiting for a delayed presention of GKTurnBasedMatchmakerViewController to complete

【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];

【参考方案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。

【讨论】：

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。
