print("GameScene:ctor called......")
self._visibleSize = cc.Director:getInstance():getVisibleSize()

self._schedulerID = nil
self._rootNode = nil
print("width:%d, height:%d", self._visibleSize.width, self._visibleSize.height)

end
程序运行时能够得到值并打印输出
function GameScene:onLoginPush(pSender, touch_type)
print(string.format("width:%d, height:%d", self._visibleSize.width, self._visibleSize.height))
end
程序运行时就会报
[LUA-print] ----------------------------------------
[LUA-print] LUA ERROR: [string "GameScene.lua"]:90: attempt to index field '_visibleSize' (a nil value)
错误呢？
