title: How to use an xcode game on unity3d
body: <p>I have a game built on xcode using objective c. this game needs to be integrated with another game developed in unity3d as a part of it. how can i do this? what plugins are available to achieve this?? </p>
  
  <p>The thing is that.. i have a unity3d game and i have few other games inside the main game(games inside one game). these small games are already built on xcode.. now i have to use these games inside the main unity game.. something like if i chose to play one of the games it has to load that particular xcode game.. how can i achieve this?? also if this is achieved.. can i build it on unity-android and expect it to work? or do i have to do it differently for android? Please guide..</p>
