-- If scene's view is removed, scene:destroyScene() will be called just prior to:

    -- INSERT code here (e.g. remove listeners, remove widgets, save state variables, etc.)

-- END OF YOUR IMPLEMENTATION
-----------------------------------------------------------------------------------------

-- "createScene" event is dispatched if scene's view does not exist
scene:addEventListener("createScene", scene)

-- "enterScene" event is dispatched whenever scene transition has finished
scene:addEventListener("enterScene", scene)

-- "exitScene" event is dispatched whenever before next scene's transition begins
scene:addEventListener("exitScene", scene)

-- "destroyScene" event is dispatched before view is unloaded, which can be
-- automatically unloaded in low memory situations, or explicitly via a call to
-- storyboard.purgeScene() or storyboard.removeScene().
scene:addEventListener("destroyScene", scene)
