Best practices for GUI

Unity Engine
1

I’ve seen and used four different mechanisms for UI design.

  1. Separate camera for all GUI work
  2. OnGUI calls
  3. GUITextures on the main camera
  4. GUI ‘objects’ that are children of the main camera.

Is there one of those that works best for iOS development? Is there any benefit to keeping all of the GUI on its own camera?

Thanks!
