iOS的swift中的websocket用的库是：starscream。
用websocket接收消息，刚开始连接后，收发消息一直是正常的。
但是过了段时间，大概不到10分钟，然后就无法正常接收到，别的（web）端发送到消息了
然后后来发现android端也出现类似问题：web socket的disconnect也没有监听到
然后也是过了段时间就收不到消息了
搜：
websocket ios not receive
服务器端，默认的设置是：3600000毫秒
搜：
session timeout设置
请教：如何设置session的超时时间，它的默认超时时间是多少？谢谢！！！-CSDN论坛-CSDN.NET-中国最大的IT技术社区

后来发现是服务器端，web socket出现异常：EOF
然后好像是IP出错？
出错的IP是192.168.1.107
而不是我的IP 192.168.1.111

－》在app进入后台，假装借用CLLocationManager去保持位置更新
从而使app的websocket仍然连接
从而保证收发消息正常。。。

daltoniam/Starscream: Websockets in swift for iOS and OSX
里面自带：
socket.writePing(NSData()) //example on how to write a ping control frame over the socket!
那就去试试：每隔2分钟，发送一个ping到服务器，看看最后效果
代码加了：
webSocket.writePing(NSData())
变成：
func websocketKeepConnect(){
gLog.debug("gCurUserItem.hasLogined=\(gCurUserItem.hasLogined), gCurUserItem.wsInited=\(gCurUserItem.wsInited)")
if gCurUserItem.hasLogined && gCurUserItem.wsInited {
gLog.info("connect \(webSocket)")
//no matter is connected or not, force connect it to send noop to server to keep websocket alive
webSocket.connect()
webSocket.writePing(NSData())
}
}
结果就可以了：web socket就不会断了。就可以正常收发消息了。

然后后来收到了pong的响应：
