Airplay Secondary screen show Cocos2dx Scene

I want to use airplay to develop dual screen for game play.
My Target is:
Content platform
Main UIScreen show Cocos2dx Scene Controller,Ex:Move button,Pause button… ios device
Secondary UIscreen show another Cocos2dx Scene GameScene Viewer,Ex:Role,Collider,Decorator… mac or appleTV

I refer https://github.com/quellish/AirplayDemo/ ,and add AirplayDemoViewController class
If I add AirplayDemoViewController into mainScreen and secondary screen,
and it only show “1” in mainScreen, show “2” in secondary screen.That’s ok,but this is not what I want.

The first problem is:
Cocos2dx seem don’t support dual scene renderering at the same time.
How to support dual Scene?

The second problem is:
If I only add AirplayDemoViewController into secondary screen
How to put the another Scene cocos2dx code into AirplayDemoViewController.

Have any idea to do?
Thanks.
Regards.
