Is there anyway to register the unity ios app with the system, so that a variable can be passed in or just launching the game direct from a website.
Like kindle uses kindle:///theEmail:mm@m.com
Which sends u directly into kindle app.
Or to launch iBooks with a PDF?
To register your app to handle an url type, you just need to add the url type to your Info.plist. Then you need to write some Objectice-C code to handle the url. I assume that should be possible by modifying the XCode project and using Unity’s plugin mechanism, but I haven’t tried. Check out this document.
