我正在尝试使用自定义UI(没有gkmatchmakerViewController)实现实时多人游戏.我正在使用startbrowsingForNearbyPlayersWithReachableHandler：^(Nsstring * playerID,BOOL可达)来查找本地播放器,然后使用gkmatchmaker单例(我已经启动)发起匹配请求.
这是我遇到麻烦的地方.当我发送请求时,完成处理程序几乎立即触发,没有错误,并且它返回的匹配具有预期的玩家计数为零.同时,其他玩家肯定没有回复该请求
相关守则：
- (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];
}
}];
}
我从上一个问题(iOS Gamecenter Programmatic Matchmaking)中知道我需要包含这个：
- (void)matchForInvite:(GKInvite *)invite completionHandler:(void (^)(GKMatch *match,NSError *error))completionHandler
在上面的代码,但我不知道应该包括在哪里.我已经尝试过GKMatchRequest inviteeResponseHandler和matchmaker finMatchForRequest：withCompletionHandler都无济于事.发生的行为是匹配器立即返回匹配(甚至在被邀请者被邀请之前),并且即使在被邀请者点击匹配邀请之后也不会调用matchRequest inviteeResponseHandler.
有人可以就此提出建议吗？谢谢.

解决方法
今晚我的比赛正在进行中.为了获得通信通道设置,您需要进行更多的协商.返回给邀请者的初始匹配正在等待被邀请者回复…这是我的过程只有两个玩家.以下是我的通信启动执行的所有步骤.显然,此处不包含真正的错误处理：
首先,验证您的播放器
第二,在认证设置inviteHandler之后.像这样的东西：
[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,获取朋友playerIds(不是别名)的列表.
第四,设置这样的GKMatchRequest ……我只邀请一位朋友：
// 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,使用请求调用findMatchForRequest：withCompletionHandler：这样的……
[[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...
}
}];
第六,这将请求发送给另一个玩家,如果他们接受来自第二步的“inviteHandler”则被调用.
第七,来自第二步的“inviteHandler”获得了GKInvite的比赛！
第八,来自第四步的“inviteeResponseHandler”被召唤完成比赛！
第九,从GKMatchDelegate创建一个didChangeState来处理匹配的最终化.像这样的东西：
- (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]];
}
}}
第十,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 - '%@'",action);
}
}
else
{
NSLog(@"DEBUG: Message sent to players (%@) - '%@'",action);
}}
第十一,从GKMatchDelegate创建一个这样的didReceiveData：
- (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,thanks for inviting,self.MM_gameCenterLocalPlayer.alias] toPlayersInMatch: [NSArray arrayWithObject:playerID]];
}
// Execute the action we were sent...
NSLog(actionString);}
第十二……好了,现在你已经开始运行了沟通渠道……做你想做的事……
