I am trying to create animations in an ebook (using iBooks Author) much like the the first few pages of Yellow Submarine ebook.
Specifically I want to have animations in the content and immediately animate and interactable without the need to trigger (touch to turn on) a widget. I tried HTML5 (like the sencha demo) as well as keynote. But both of those ended up creating a selectable widget where the animation would not happen w/o selecting the widget.
Why not sync the book which has the functionality you want to iTunes? - Then find the book which is then synced to your PC/Macs hard drive and open it in an editor and look at the XML/Pub 3 script. This may give you some clues as to how they are doing it.
The iBook format is an Apple extended version of EPub v 3
I would be very surprised if it can't be done from the IBooks Author tool.
If the Book you wish to examine has DRM you could still look at it by using a tool like: Requiem 3.3
