已弃用GKMatchMaker邀请处理程序

我有我以前用来处理邀请的以下代码：

[GKMatchmaker sharedMatchmaker].inviteHandler = ^(GKInvite *acceptedInvite, NSArray *playersToInvite) { // Insert game-specific code here to clean up any game in progress. if (acceptedInvite) { GKMatchmakerViewController *mmvc = [[GKMatchmakerViewController alloc] initWithInvite:acceptedInvite]; mmvc.matchmakerDelegate = self; [self presentViewController:mmvc animated:YES completion:nil]; } }; 

但是，现在已经在iOS 7被弃用了。 在哪里以及如何在我的项目中注册GameKit邀请处理程序？

GKInviteEventHandler来救援，并特别看看GKLocalPlayerListener 。

符合GKLocalPlayerListener协议，你应该没问题。 以下是协议方法，它们看起来是inviteHandler的预期替代，但分为两部分。

 - (void)player:(GKPlayer *)player didAcceptInvite:(GKInvite *)invite - (void)player:(GKPlayer *)player didRequestMatchWithPlayers:(NSArray *)playerIDsToInvite 

设置一些对象以符合该对象之后，您只需调用registerListener:

 [[GKLocalPlayer localPlayer] registerListener:yourObjectHere] 

不要担心尽快注册，因为系统会caching邀请/挑战/回合的内容，如果没有人来处理这些内容，并且只要设置好，就可以让听众知道。

正如Sam所说的那样，新的方法是使用GKLocalPlayerListener协议。 现在这个方法被颠倒了。 在过去，您从部分应用程序向其他玩家发出邀请。 另一部分听取了另一位玩家的邀请，并对此作出了回应。 现在，您可以使用matchMakerViewController 或 Game Center发出邀请（与之前一样），但是现在您可以听取这些邀请的接受了。 之后，Game Center调用didFindMatch来启动一切。 如果您正在收到邀请，Game Center开始您的游戏，然后调用didFindMatch启动它。

这是我的代码：

在我的.h文件GKLocalPlayerListener协议：

 @interface MNFStartupViewController : UIViewController<ADBannerViewDelegate, GKMatchmakerViewControllerDelegate, GKMatchDelegate, GKLocalPlayerListener, UIAlertViewDelegate> 

在本地玩家进行身份validation之后，在我的authenticateHandler块的.m文件中：

 [[GKLocalPlayer localPlayer] registerListener:self]; 

那么听方法来接受一个邀请：

 -(void)player:(GKPlayer *)player didAcceptInvite:(GKInvite *)invite{ //Called when another player accepts a match invite from the local player. NSLog(@"didAcceptInvite was called: Player: %@ accepted our invitation", player); GKMatchmakerViewController *mmvc = [[GKMatchmakerViewController alloc] initWithInvite:invite]; mmvc.matchmakerDelegate = self; [self presentViewController:mmvc animated:YES completion:nil];} 

现在用Game Center中的一组玩家从Game Center开始游戏的方法。 这很难debugging，因为你不能在Game Center中同时从Xcode运行游戏（我不这么认为），所以有一个debugging的AlertView可以被删除。

 -(void)player:(GKPlayer *)player didRequestMatchWithPlayers:(NSArray *)playerIDsToInvite{ //Called when the local player starts a match with another player from Game Center //Start of debugging logging and alerting NSLog(@"In didRequestMatchWithPlayers for players: %@", playerIDsToInvite); NSString *logString = [[NSString alloc] initWithFormat:@"didrequestMatchWithPlayers was called with player IDs: %@", playerIDsToInvite]; UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Logging Alert" message:logString delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil]; [alert show]; //End of debugging logging and alerting //Create a match for the chosen players GKMatchRequest *match = [[GKMatchRequest alloc]init]; match.playersToInvite = playerIDsToInvite; //Create a matchmaking viewcontroller for that match GKMatchmakerViewController *mmvc = [[GKMatchmakerViewController alloc]initWithMatchRequest:match]; mmvc.matchmakerDelegate = self; [self presentViewController:mmvc animated:YES completion:nil];} 

这是启动整个配对过程的一种方法：

 -(IBAction)setupMatch:(id)sender{ GKMatchmakerViewController *matchViewController = [[GKMatchmakerViewController alloc] initWithMatchRequest:matchRequest]; matchViewController.matchmakerDelegate = self; [self presentViewController:matchViewController animated:YES completion:nil];} 

最后，这是Game Center调用的方法，当所有玩家连接并准备就绪时，设置比赛进行。 currentPlayer，currentMatch和hostingPlayer是我自己的属性，具有明显的用途。

 -(void)matchmakerViewController:(GKMatchmakerViewController *)viewController didFindMatch:(GKMatch *)match{ //Called when GameCenter completes the auto matchmaking process match.delegate = (id)self; [self setCurrentMatch:match]; [self setCurrentPlayers:match.playerIDs]; NSLog(@"Match was found with players: %@, time to get on with the game.", self.currentPlayers); //Use the built in features to decide which device should be the server. self.hostingPlayer = [self chooseHostingPlayerIDfromPlayerIDs:self.currentPlayers]; [self dismissViewControllerAnimated:YES completion:nil];} 

希望能帮助到你。

另外，请仅在设备上工作。 我无法邀请在iOS 8.1的模拟器中工作。

Answer 4

我相信GKMatch和GKTurnBasedMatch的答案令人讨厌。

对于GKTurnBasedMatch ，邀请会被视为转向事件，并在此function中处理：

player(_ player: GKPlayer, receivedTurnEventFor match: GKTurnBasedMatch, didBecomeActive: Bool)

这在GKLocalPlayerListener协议中。 您必须正式注册GKLocalPlayerListener实例与您的本地播放器才能正常工作，因此您只能在validation后执行此操作。

…并不总是工作。 游戏中心是不可靠的。 但有时它确实有效，那是…什么？
