Preview does not identify all problems?

Question

I used iBooks Author to make a fairly elaborate book (Cosmic Cat) and published it on iTiunes. Lacking an iPad, I previewed it on my Mac using iBooks, where it works perfectly, including all the various widgets. However, people who have bought the book for their iPads tell me that one of the widgets, a Keynote presentation, does not work (although the other Keynotes all do). I have no clue about how to fix this. Even if I had an iPad, I'm not sure I'd learn anything except that it does not work. Apple Support offers no help or suggestions other than to pay an outside source to assemble my book. Does anyone have any suggestions about how I should approach this?

Answer 1

I have seen many times with problems, that author either blames some part of Apple system to create, deliver and sell books.     It usually tuns out to the  problem is within the book - the  Pain... is finding it.
I have seem the  online video - which is brilliant, but  that  does not show the problem.
I would  take two lines on this, the first being to contact  the review team and ask how your book passed into the store when it seems  buyers are reporting a a glaring problem with a widget, and ask if they can check the iBooks version.
Second is to revisit your  widget construction.
Have you  analysed what  - if anything is different with the one Keynote giving a problem, than the others which are OK.
Have you  tried rebuilding the Keynote?  if not perhaps  you can  open a new  "practice" book and  use it to test the Keynote without risk to the main project master files.
Additionally, I would suggest you start a new post on iBooks Author discussiuon group, many  of the user of iBA, do not check out other groups, and maybe you will find more Keynotes users who have  the knowledge I lack to help you.
