如何避免websocket被jsb回收掉

Cocos2d-x JavaScript
#1

if (this.gameSocket && (this.gameSocket.readyState == 1)) {

结果

jsb: ERROR: File d:\game\frameworks\js-bindings\bindings\manual\network\jsb_websocket.cpp: Line: 328, Function: js_cocos2dx_extension_WebSocket_get_readyState
Invalid Native Object

websocket被释放了

#2

retain()方法？？
