This means that iBooks is indexing your large database of content. You need to disable all passcode and autolock features, and just let it run for 1 to 2 hours. You need to let it go through this process every time you add books and PDFs. The more you add, the longer it takes to index.
My best solution is to use GoodReader for PDFs. It never needs to index like iBooks.
It is unfortunate that Apple has not caught this bug yet.
It is just like when you upgrade to a new version of OS X. Spotlight takes some time to index your hard drive.
I thought it might be something like this, so I've left iBooks open for long stretches and it just never seems to stop. Then again, maybe it just needs a lot more time. I'll leave it open overnight and see if the issue is fixed. I'm actually installing a new update to iBooks right now, so maybe it will be fixed even sooner.
I can hope…
Thanks for the reply! :)
I would avoid iBooks 3. As an example, I had that wheel spinning for 40-hours on my iPad 2 only to learn that iBooks 3.0 does not work.
I went back to the previous iBooks via my back up. The entire process had taken 2-hours.
My best advice is to use GoodReader. I have been using it extensively over the last 2-years, and I have never had a single issue on any device.
Good luck, and let us know!
The new update fixed this issue and others I had with iBooks. I'm not sure if leaving it open to reindex would have worked or not, since the updated version re-indexed my 3,025-or-so books in just a few minutes. My searches in PDFs and books with thousands of pages are much faster as well.
Altogether, a good update!
It would be nice, but my iPad is hooked up to an exchange server so it can only stay 'open' for 15 minutes before locking, and I'm guessing that iBooks stops then. Wonder if I have to just sit and babysit and touch the screen every 10 minutes or so...
Would love some sort of progress meter or something...
