我确实看过将数据包发送到 Minecraft 服务器的问题：Objective-C

如果他们在此处使用此链接，则可能是相关的：Protocol - Minecraft Server但是，他们没有使用该链接。他们使用主要用于一般信息的 wiki。我引用的是创建一个新客户端。但是，当我在 IRC 上询问时。他们说话就像我什么都不知道一样。所以，我在这里问。

 How do i Send the packet correctly with the fields to Minecraft server?

请注意，Minecraft 服务器的代码在网站上。

我拥有的代码，连接到服务器，Minecraft 服务器上的输出如下所示：

 [INFO] Disconnecting /192.168.1.4:60911: Took too long to log in
 [INFO] Disconnecting /192.168.1.4:60915: Took too long to log in
 [INFO] Disconnecting /192.168.1.4:60927: Took too long to log in
 [INFO] /192.168.1.4:60934 lost connection
 [INFO] Disconnecting /192.168.1.4:60954: Took too long to log in

我如何正确发送这些数据包？

 NSUserDefaults *defs = [NSUserDefaults standardUserDefaults];
    unsigned char *ch[] = {0x02, [[defs stringForKey:@"Username"] UTF8String]};
    UInt8 i = (UInt8)ch;
    NSData *requestData = [NSData dataWithBytes:&i length:sizeof(i)];


    NSString *reqLog = [[NSString alloc] initWithData:requestData encoding:NSUTF8StringEncoding];

    [asyncsocket writeData:requestData withTimeout:-1.0 tag:0];

    //[asyncsocket readDataToData:[GCDAsyncSocket LFData] withTimeout:-1.0 tag:0];

    [asyncsocket readDataToLength:5 withTimeout:-1.0 tag:0];

    /*NSData *responseTerminatorData = [@"\n" dataUsingEncoding:NSASCIIStringEncoding];

     [asyncsocket readDataToData:responseTerminatorData withTimeout:-1.0 tag:0];*/

最后说明：IOS5 是此应用程序的平台
