我希望有人能夠幫助解決Objective-C問題，它涉及使用GameCenter一次在兩個設備之間發送和接收信息他們已經通過配對。Objective-C：無法在使用Game Center的兩個配對兩個設備之後發送/接收數據
我正在使用一本叫做Beginning iOS Game Center和Game Kit的教科書作爲我的嚮導，它正在通過一個示例程序，但我被卡在想從設備上播放遊戲的數據中。
我可以成功matchmake兩個設備和相應的視圖出現。我在我的GameCenterManager.m文件中的兩個函數來發送信息 - 一個是以下幾點：
- (void)sendStringToAllPeers:(NSString *)dataString reliable:(BOOL)reliable
{
NSLog(@"Send String To All Peers");
NSLog(@"Data String: %@", dataString);
NSLog(@"match or session %@", self.matchOrSession);
if (self.matchOrSession == nil)
{
NSLog(@"GC Manager matchorsession ivar was not set - this needs to be set with the GKMatch or GKSession before sending or receiving data");
return;
}
NSData *dataToSend = [dataString dataUsingEncoding:NSUTF8StringEncoding];
GKSendDataMode mode;
if (reliable)
{
mode = GKSendDataReliable;
}
else{
mode = GKSendDataUnreliable;
}
NSError *error = nil;
if ([self.matchOrSession isKindOfClass:[GKSession class]])
{
NSLog(@"Match or session 1");
NSLog(@"Data to send: %@", dataToSend);
[self.matchOrSession sendDataToAllPeers:dataToSend withDataMode:mode error:&error];
}
else if ([self.matchOrSession isKindOfClass:[GKMatch class]])
{
NSLog(@"Match or session 2");
NSLog(@"Data to send: %@", dataToSend);
[self.matchOrSession sendDataToAllPlayers:dataToSend withDataMode:mode error:&error];
}
else
{
NSLog(@"GC Manager matchOrSession was not a GKMatch or a GK Session, we are unable to send data");
}
if (error != nil)
{
NSLog(@"An error occurred while sending data %@", [error localizedDescription]);
}
}
這個功能，我從一個函數在我racetohundredViewController.m文件稱：
- (void)generateAndSendHostNumber;
{
NSLog(@"Generate and send host number");
randomHostNumber = arc4random();
NSString *randomNumberString = [NSString stringWithFormat: @"$Host:%f", randomHostNumber];
NSLog(@"the random number string is: %@", randomNumberString);
[self.gcManager sendStringToAllPeers:randomNumberString reliable: YES];
}
我順利拿到由此產生的以下NSLog輸出：
2013-01-02 22:27:43.519 First to 50[1376:907] Send String To All Peers
2013-01-02 22:27:43.520 First to 50[1376:907] Data String: $Host:2087825492.000000
2013-01-02 22:27:43.521 First to 50[1376:907] match or session <GKMatch 0x200853d0 expected count: 0 seqnum: 2

2013-01-02 22:27:43.522 First to 50[1376:907] Match or session 2
2013-01-02 22:27:43.523 First to 50[1376:907] Data to send: <24486f73 743a3230 38373832 35343932 2e303030 303030>
因此，我可以看到'數據發送'輸出，它非常棒。
不過我現在命令
[self.matchOrSession sendDataToAllPeers:dataToSend withDataMode:mode error:&error];
這似乎並沒有帶我在任何地方都沒有。我在GameCenterManager.m中有以下功能：
- (void)receiveData:(NSData *)data fromPeer:(NSString *)peer inSession: (GKSession *)session context:(void *)context
{
NSLog(@"*****Receive Data In Session");
NSString *dataString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSDictionary *dataDictionary = [NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:dataString, peer, session, nil] forKeys:[NSArray arrayWithObjects: @"data", @"peer", @"session", nil]];
[self callDelegateOnMainThread: @selector(receivedData:) withArg: dataDictionary error: nil];
}
但是我沒有看到NSLog的輸出。同樣，我在我的racetohundredViewController.m文件中有一個函數
- (void)receivedData:(NSDictionary *)dataDictionary
{
NSLog(@"------Received Data");
}
這也不會被調用;可能是因爲之前的功能無法調用它。
我一直在試圖弄清楚爲什麼這一段時間不工作而沒有任何效用。任何人都可以指出我要去哪裏嗎？我希望我已經輸入了所有相關的代碼，但如果您有任何問題，請詢問。
感謝所有，提前。
