当我在 Swift 中设置 GKMatchmakerViewControllerDelegate 时出现错误？

Question

我想为我的游戏设置配对viewController。为此，我将 GKMatchmakerViewControllerDelegate 委托添加到名为 Home 的主 UIViewController 中，这样它看起来像：

class Home: UIViewController, GKGameCenterControllerDelegate, GKMatchmakerViewControllerDelegate {

要加载配对界面，我正在使用此代码：

func openMatchmaker() {
    var gcViewController: GKMatchmakerViewController = GKMatchmakerViewController(rootViewController: self)

    gcViewController.matchmakerDelegate = self

    gcViewController.hosted = false
    gcViewController.matchRequest.minPlayers = 2
    gcViewController.matchRequest.maxPlayers = 2
    gcViewController.matchRequest.defaultNumberOfPlayers = 2

    self.showViewController(gcViewController, sender: self)
    self.navigationController?.pushViewController(gcViewController, animated: true)
}

不过，当我尝试运行代码时，接下来 class Home: ... 收到以下错误。错误消息说：

 Type 'Home' does not conform to protocol `GKMatchmakerViewControllerDelegate`.

为什么会这样？

Answer 1

大多数情况下，您遇到该错误是因为您没有实现特定协议所需的功能。您可以通过命令单击该协议来查看它们。添加以下方法：

func matchmakerViewController(viewController: GKMatchmakerViewController!,
    didFailWithError error: NSError!) {
}

func matchmakerViewController(viewController: GKMatchmakerViewController!,
    didFindHostedPlayers players: [AnyObject]!) {
}

func matchmakerViewControllerWasCancelled(viewController: GKMatchmakerViewController!) {
}

func matchmakerViewController(viewController: GKMatchmakerViewController!,
    hostedPlayerDidAccept player: GKPlayer!) {
}

Answer 2

批准答案中的第二个函数已更新到最新的 SDK 中：

func matchmakerViewController(viewController: GKMatchmakerViewController, didFindHostedPlayers players: [GKPlayer]) {
   ... 
}
