**My dear friends,
I tried very hard to add scroll function in my storyboard, and now I can turn pages.
The only problem is my app still crashes sometimes. I am now pretty sure something wrong happened in my memory control. I was wondering if anyone here could kindly check the code for me, I have spent two days, and haven’t got any luck.
warm regards,
Henry

end
function p01:enterScene( event )
local group = self.view
– INSERT code here (e.g. start timers, load audio, start listeners, etc.)
end
– Called when scene is about to move offscreen:
function p01:exitScene( event )
local group = self.view
– INSERT code here (e.g. stop timers, remove listenets, unload sounds, etc.)
end
– If scene’s view is removed, scene:destroyScene() will be called just prior to:
function p01:destroyScene( event )
local group = self.view
print(“scene p01 destroyed”)
p01 = nil
audio.dispose(audio01)
audio01 = nil
end
– END OF YOUR IMPLEMENTATION
– “createScene” event is dispatched if scene’s view does not exist
p01:addEventListener( “createScene”, p01 )
– “enterScene” event is dispatched whenever scene transition has finished
p01:addEventListener( “enterScene”, p01 )
– “exitScene” event is dispatched whenever before next scene’s transition begins
p01:addEventListener( “exitScene”, p01 )
– “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().
p01:addEventListener( “destroyScene”, p01 )[code]
