//jetfire-master第三方實(shí)現(xiàn)ws的協(xié)議
（1）
self.socket = [[JFRWebSocket alloc] initWithURL:[NSURL URLWithString:@"ws://localhost:8080"] protocols:@[@"chat",@"superchat"]];
self.socket.delegate = self;
（2）實(shí)現(xiàn)代理方法
//開始連接
-(void)websocketDidConnect:(JFRWebSocket*)socket {
NSLog(@"websocket is connected");
}
//斷開連接
-(void)websocketDidDisconnect:(JFRWebSocket*)socket error:(NSError*)error {
NSLog(@"websocket is disconnected: %@", [error localizedDescription]);
//? ? [self.socket connect];
}
//連接成功接收到的字符串家凯，可以使用分割字符串的方法進(jìn)行解析显晶，也可以將字符串轉(zhuǎn)化為data格式随抠，再轉(zhuǎn)化為json格式進(jìn)行解析
-(void)websocket:(JFRWebSocket*)socket didReceiveMessage:(NSString*)string {
}
//連接成功接收到的data
-(void)websocket:(JFRWebSocket*)socket didReceiveData:(NSData*)data;
（3）可以設(shè)置按鈕來發(fā)送消息（里面加一個定時器产喉，實(shí)時接收消息）
- (IBAction)btnAc:(id)sender
{
//開始連接
[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];
}
//設(shè)置按鈕停止信息傳輸
- (IBAction)btnStopAc:(id)sender
{
[timer invalidate];
timer = nil;
//斷開連接
[self.socket disconnect];
[recorder stop];
}
