注册了触摸事件，在响应时想按下添加一个layer，释放时移除这个layer 结果报错了 查不到原因
function Map:onCellTouch(event)
if not self.mapEditor then
self:initUIMapEditor();
end
if event.name == “began” and not self._displayeditor then
self._displayeditor = true;
print(self.mapEditor, “show”)
self.mapEditor:addTo(self.layer);
elseif event.name == “ended” and self._displayeditor then
self._displayeditor = false;
print(self.mapEditor, “hide”)
self.mapEditor:removeSelf()
end
return true
end
运行时会报诡异错误：
userdata show
LUA ERROR: :69: invalid ‘cobj’ in function ‘lua_cocos2dx_Node_getLocalZOrder’
