2.1.1.先去github上下载 AsyncUdpSocket.h框架包
2.1.2.初始化udp

@interface
QCViewController (){ AsyncUdpSocket *asyncUdpSocket;} asyncUdpSocket = [[AsyncUdpSocket alloc] initWithDelegate:self]; |
2.1.3.绑定端口

NSError
*err = nil; [asyncUdpSocket enableBroadcast:YES
error:&err]; [asyncUdpSocket bindToPort:9527 error:&err];//启动接收线程 [asyncUdpSocket receiveWithTimeout:-1 tag:0]; |
2.1.4.实现代理方法

//已接收到消息- (BOOL)onUdpSocket:(AsyncUdpSocket *)sock didReceiveData:(NSData
*)data withTag:(long)tag fromHost:(NSString
*)host port:(UInt16)port{ if(data是找服务器的){ //根据客户端给的IP，利用TCP或UDP 相互连接上就可以开始通讯了 } return
YES;}//没有接受到消息-(void)onUdpSocket:(AsyncUdpSocket *)sock didNotReceiveDataWithTag:(long)tag dueToError:(NSError
*)error{}//没有发送出消息-(void)onUdpSocket:(AsyncUdpSocket *)sock didNotSendDataWithTag:(long)tag dueToError:(NSError
*)error{ }//已发送出消息-(void)onUdpSocket:(AsyncUdpSocket *)sock didSendDataWithTag:(long)tag{}//断开连接-(void)onUdpSocketDidClose:(AsyncUdpSocket *)sock{} |
注：实现步骤与服务器端相似

2.2.4.广播寻找
注：广播iP地址为 255.255.255.255
