[請益] 請教關於ＧＣＤAsyncSocket

[areyo (沒有名字的怪物)]

大家午安
小弟剛進入ios的開發世界,第一次使用第三方庫gcdasyncsocket來寫client

照了作者github實作init 成功了 也連到server, 此時server會送字串出來

我client去收卻說socket已斷了

可我用netstat -nap tcp看連線還建立著
是我少了什麼步驟嗎？

-(void) didInitNetwork{
    myAsyncSocket =[[GCDAsyncSocket alloc]
                    initWithDelegate:self delegateQueue:dispatch_get_main_queue()];
 NSError *nsErr=nil;
    [myAsyncSocket connectToHost:@"192.168.1.102" onPort:31010 error:&nsErr];

    }

//receive button
- (IBAction)receive_data_btn:(id)sender {
if([myAsyncSocket isConnected]==YES)
    {
       [myAsyncSocket readDataToData:[GCDAsyncSocket CRLFData] withTimeout:-1 tag:1];
    }
}

//callback
- (void)socket:(GCDAsyncSocket *)sock didReadData:(NSData *)data withTag:(long)tag{
    NSData *strData = [data subdataWithRange:NSMakeRange(0, [data length] - 2)];
    NSString *msg = [[NSString alloc] initWithData:strData encoding:NSUTF8StringEncoding];
    NSLog(msg);
    self.status_label.text=msg;
}
