我试图实现实时多人游戏的自定义UI（无GKMatchMakerViewController）。 我使用startBrowsingForNearbyPlayersWithReachableHandler：^（的NSString * playerID，BOOL可达）找到当地的球员，然后启动与GKMatchmaker单（我已经开始）的匹配要求。
这里就是我在遇到麻烦。 当我发送一个请求，完成处理器几乎立即触发，没有一个错误，并返回匹配具有零期望球员计数。 与此同时，其他球员绝对没有回应请求
相关的代码：
- (void) findMatch {
GKMatchRequest *request = [[GKMatchRequest alloc] init];
request.minPlayers = NUM_PLAYERS_PER_MATCH; //2
request.maxPlayers = NUM_PLAYERS_PER_MATCH; //2
if (nil != self.playersToInvite) {
// we always successfully get in this if-statement
request.playersToInvite = self.playersToInvite;
request.inviteeResponseHandler = ^(NSString *playerID, GKInviteeResponse response) {
[self.delegate updateUIForPlayer: playerID accepted: (response == GKInviteeResponseAccepted)];
};
}
request.inviteMessage = @"Let's Play!";
[self.matchmaker findMatchForRequest:request withCompletionHandler:^(GKMatch *match, NSError *error) {
if (error) {
// Print the error
NSLog(@"%@", error.localizedDescription);
} else
if (match != nil) {
self.currentMatch = match;
self.currentMatch.delegate = self;
// All players are connected
if (match.expectedPlayerCount == 0) {
// start match
[self startMatch];
}
[self stopLookingForPlayers];
}
}];
}
我从以前的问题（知道iOS版的GameCenter编程对接会 ），我需要包括这样的：
- (void)matchForInvite:(GKInvite *)invite completionHandler:(void (^)(GKMatch *match, NSError *error))completionHandler
在上面的代码，但我不知道在哪里应该包括在内。 我已经尝试过了两个GKMatchRequest inviteeResponseHandler，并在媒婆finMatchForRequest：withCompletionHandler无济于事。 出现这种情况的行为是媒人立刻返回匹配（受邀者已受邀甚至更早），甚至后被邀请者水龙头比赛邀请matchRequest inviteeResponseHandler永远不会被调用。
有人可以在此建言？ 谢谢。

我刚刚得到了今晚我的比赛这方面的工作。 还有就是你需要做的就是通信信道建立更多的谈判筹码。 回到邀请最初的比赛在等待被邀请人回应......这是我的过程，只有两名球员。 这里是我所有的通信自旋向上的执行步骤。 很显然，这里包括没有真正的错误处理：
首先，验证您的播放器
二，右后验证设置inviteHandler。 事情是这样的：
[GKMatchmaker sharedMatchmaker].inviteHandler = ^(GKInvite* acceptedInvite, NSArray *playersToInvite)
{
if(acceptedInvite != nil)
{
// Get a match for the invite we obtained...
[[GKMatchmaker sharedMatchmaker] matchForInvite:acceptedInvite completionHandler:^(GKMatch *match, NSError *error)
{
if(match != nil)
{
[self disconnectMatch];
// Record the new match...
self.MM_gameCenterCurrentMatch = match;
self.MM_gameCenterCurrentMatch.delegate = self;
}
else if(error != nil)
{
NSLog(@"ERROR: From matchForInvite: %@", [error description]);
}
else
{
NSLog(@"ERROR: Unexpected return from matchForInvite...");
}
}];
}
};
第三，让您的朋友playerIds（非别名）的列表。
四，设置您GKMatchRequest这样的事情...我只邀请一个朋友：
// Initialize the match request - Just targeting iOS 6 for now...
GKMatchRequest* request = [[GKMatchRequest alloc] init];
request.minPlayers = 2;
request.maxPlayers = 2;
request.playersToInvite = [NSArray arrayWithObject:player.playerID];
request.inviteMessage = @"Let's play!";
// This gets called when somebody accepts
request.inviteeResponseHandler = ^(NSString *playerID, GKInviteeResponse response)
{
if (response == GKInviteeResponseAccepted)
{
//NSLog(@"DEBUG: Player Accepted: %@", playerID);
// Tell the infrastructure we are don matching and will start using the match
[[GKMatchmaker sharedMatchmaker] finishMatchmakingForMatch:self.MM_gameCenterCurrentMatch];
}
};
五，使用请求来调用findMatchForRequest：withCompletionHandler：这样的事情...
[[GKMatchmaker sharedMatchmaker] findMatchForRequest:request withCompletionHandler:^(GKMatch* match, NSError *error) {
if (error)
{
NSLog(@"ERROR: Error makeMatch: %@", [error description] );
[self disconnectMatch];
}
else if (match != nil)
{
// Record the new match and set me up as the delegate...
self.MM_gameCenterCurrentMatch = match;
self.MM_gameCenterCurrentMatch.delegate = self;
// There will be no players until the players accept...
}
}];
六，本次将请求发送到其他球员，如果他们接受第二步“inviteHandler”被调用。
第七，“inviteHandler”从第二步获得了比赛的GKInvite！
第八，“inviteeResponseHandler”从第四步被调用它完成了比赛！
第九，创建一个GKMatchDelegate到didChangeState处理比赛的最后定稿。 事情是这样的：
- (void)match:(GKMatch *)match player:(NSString *)playerID didChangeState:(GKPlayerConnectionState)state{
switch (state)
{
case GKPlayerStateConnected:
// Handle a new player connection.
break;
case GKPlayerStateDisconnected:
// A player just disconnected.
break;
}
if (!self.matchStarted && match.expectedPlayerCount == 0)
{
self.matchStarted = YES;
// Handle initial match negotiation.
if (self.iAmHost && !self.sentInitialResponse)
{
self.sentInitialResponse = true;
// Send a hello log entry
[self sendMessage: [NSString stringWithFormat:@"Message from friend, 'Hello, thanks for accepting, you have connected with %@'", self.MM_gameCenterLocalPlayer.alias] toPlayersInMatch: [NSArray arrayWithObject:playerID]];
}
}}
十五，这是我的sendMessage：
- (void) sendMessage:(NSString*)action toPlayersInMatch:(NSArray*) playerIds{
NSError* err = nil;
if (![self.MM_gameCenterCurrentMatch sendData:[action dataUsingEncoding:NSUTF8StringEncoding] toPlayers:playerIds withDataMode:GKMatchSendDataReliable error:&err])
{
if (err != nil)
{
NSLog(@"ERROR: Could not send action to players (%@): %@ (%d) - '%@'" ,[playersInMatch componentsJoinedByString:@","],[err localizedDescription],[err code], action);
}
else
{
NSLog(@"ERROR: Could not send action to players (%@): null error - '%@'",[playersInMatch componentsJoinedByString:@","], action);
}
}
else
{
NSLog(@"DEBUG: Message sent to players (%@) - '%@'",[playersInMatch componentsJoinedByString:@","], action);
}}
十一，创建一个didReceiveData从GKMatchDelegate是这样的：
- (void)match:(GKMatch *)match didReceiveData:(NSData *)data fromPlayer:(NSString *)playerID{
NSString* actionString = [[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding] autorelease];
// Send the initial response after we got the initial send from the
// invitee...
if (!self.iAmHost &&!self.sentInitialResponse)
{
self.sentInitialResponse = true;
// Send a hello log entry
[self sendMessage: [NSString stringWithFormat:@"Message from friend, 'Hello, thanks for inviting, you have connected with %@'", self.MM_gameCenterLocalPlayer.alias] toPlayersInMatch: [NSArray arrayWithObject:playerID]];
}
// Execute the action we were sent...
NSLog(actionString);}
第十二......那么现在你有沟通渠道和运行...做你想做...
