websocket

//jetfire-master第三方实现ws的协议

（1）

self.socket = [[JFRWebSocket alloc] initWithURL:[NSURL URLWithString:@"ws://localhost:8080"] protocols:@[@"chat",@"superchat"]];

self.socket.delegate = self;

（2）实现代理方法

//开始连接

-(void)websocketDidConnect:(JFRWebSocket*)socket {

NSLog(@"websocket is connected");

}

//断开连接

-(void)websocketDidDisconnect:(JFRWebSocket*)socket error:(NSError*)error {

NSLog(@"websocket is disconnected: %@", [error localizedDescription]);

// [self.socket connect];

}

//连接成功接收到的字符串，可以使用分割字符串的方法进行解析，也可以将字符串转化为data格式，再转化为json格式进行解析

-(void)websocket:(JFRWebSocket*)socket didReceiveMessage:(NSString*)string {

}

//连接成功接收到的data

-(void)websocket:(JFRWebSocket*)socket didReceiveData:(NSData*)data;

（3）可以设置按钮来发送消息（里面加一个定时器，实时接收消息）

- (IBAction)btnAc:(id)sender

{

//开始连接

[self.socket connect];

timer = [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(timerRun) userInfo:nil repeats:YES];

}

-(void)timerRun

{

NSData * data = [NSData dataWithContentsOfURL:urlPlay];

[self.socket writeData:data];

}

//设置按钮停止信息传输

- (IBAction)btnStopAc:(id)sender

{

[timer invalidate];

timer = nil;

//断开连接

[self.socket disconnect];

[recorder stop];

}

self.socket.delegate = self;

}

- (void)audio

{

//录音设置

recordSetting = [[NSMutableDictionary alloc]init];

//设置录音格式 AVFormatIDKey==kAudioFormatLinearPCM

//线性采样位数 8、16、24、32
