//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];
}
