title: How to launch Unity 3D App from a native iOS App
body: <p>I have an iOS project with me which was developed in Xcode 5. I also have a Unity 3D project developed in 4.3 free version. This Unity 3D project contains an animation video which I want to play. This project is already build for iOS. What I want is, I first launch my iOS App, then when I click on a button, this Unity 3D animation should play. From the Unity 3D, I should also be able to come back to the iOS App by clicking a Back button or something. To achieve this, I tried out the steps mentioned in the link below - <a href="http://alexanderwong.me/post/29949258838/building-a-ios-unity-uiview-uiviewcontroller" rel="nofollow">http://alexanderwong.me/post/29949258838/building-a-ios-unity-uiview-uiviewcontroller</a> - 
  but it didn't help; a lot of link errors were generated. This link mentions about modifying a class named AppController. I didn't find such a class in my Unity 3D project, instead I saw a class named UnityAppController instead, hence I modified that. </p>
  
  <p>Could someone guide me regarding how I can accomplish the above mentioned task. If any of you guys can provide me with some sample code that works, then it would be of great help. Thanks in advance ! </p>
