Here is my scenario:
I have scene A which calls the director to push Scene B on top of A. Now B is the current scene.
From within B, various game states change, and the user can return to A (by popping scene
I would like scene A to be aware that it is now the running scene and reload the game states changed by B.
I looked for events I could wire up for CCScene and CCGameView but I didn't come across any.
How can Scene A know that Scene B has terminated/popped?
