How to add the Joystick for iOS devises in my scene?

Hi There,

I have a 4DRoom demo, it is a 3D apartment that is working well and can be moved with mouse and keyboard.

In another scene I have a UnityiPhone Joystick and I can see the Joystick pads in to a scene called Level1_empty.unity in one folder of this project call Control Setups i have also few things called as follows:

CameraRelativeSetup.unity FirstPersonSetup.unity FirstPersonTilt.unity PlayerRelativeSetup.unity SidescrollSetup.unity TapControlSetup.unity

Well this stuff looks like they are scenes too.

When i open one, it close the one Im working on!

Is there a way to put the joystick scenes and its Control Setups Scenes in to my 4DRoom scene and make it run and test in my iPad and iPhone? How to make it? Please let me know any help or light about this topic,

sorry if this is a rookie question, I am new in all this.

Thanks and best regards, AA.
