iBooks crashes on ios 9.3

I've found that the only way to prevent iBooks crashing on the iPad 3 is to switch off iBooks in iCloud. When that's done, of course, there are no longer any books to sync from the PC. So I can either open iBooks with no books or watch it crash as it attempts to load my library. My library loads more or less correctly in iBooks on Mac (10.11.4) and an iPhone 5 (more or less - the Mac indicates lots of worrying zero byte files though managing iCloud storage shows each file at the correct size). This is a library of 2000 items, about 350 of which are PDFs.

At this point all I can think to try is rebuilding the library. Frankly, the current implementation of iBooks makes that project seem hardly worth the effort.

I have the same problem on my both iPads, Air and Air2. After iOS 9.3 upgrade iBooks freezes constantly. Even if I manage to open it, crashes. My meticulously organized over 4K books now are in chaos, all sorting is lost. Half of them are without covers, have no idea how many are lost.

I tried to reload and re-sync, nothing works. The same thing happened with my iPad 2 couple years ago when Apple issued one of their iOS update. As soon as I remember, iBooks didn't work for over a year. At least go and leave them a feedback, doubt it will help, but worth trying.

I've had some success getting iBooks on iCloud to work on my iPad 3. I found that if I signed out of my usual iCloud account and into one with no books the iBooks app would not crash when it opened. As an experiment I loaded a couple of books to that iCloud account and they worked on the iPad just fine. When I signed the iPad out of that iCloud account and in to the new one, synched it as usual to iTunes, everything worked just as it should. To do what I did you need a mac with no e-books loaded in its iBooks application and a spare iCloud account.

1. Sign a mac without any books in iBooks into a fresh iCloud account

2. Select "use iBooks in iCloud" when prompted.

3. Sign the iPad into this fresh iCloud account, and select "use iBooks in iCloud" when prompted.

(Opening the iBooks app no longer crashed under this arrangement - adding a couple of e-books to the mac's iBooks got them successfully onto the iPad.)

4. Sign the Mac and the iPad out of the fresh iCloud account

5. Sign the iPad into the existing account with ebooks available.

(don't know if it's necessary, but I synched the iPad with iTunes at this point - iTunes copied books, though not PDFs, during the sync.)

6. Open up the iBooks app on the iPad - the entire library is present and functions as it should without crashes. New additions appear as books available in the cloud on the iPad.

Had this not worked, the next thing on my list of things to try was to wipe out my existing iBooks library and reconstructing it - adding a few back at a time.

Your efforts and helpfulness are appreciated, but why should we have to do this????? We should just be able to use the **** app and access our books without all this hassle!!! (Not angry with you. Angry at Apple!!!!!!)

I've the same issue with PDF files. All wasworkingfinebeforethe update to 9.3.1

iPad mini, iOS 9.3.1

Typical engineers that continue to make this product crap! When is a apple going to hire qualified QA Real Users before they release crap. Engineers think INSIDE the box, real people think OUTSIDE the box!

Same problem with iBooks crashes since iOS 9.3.x, on my ipad Mini. In contrast my iphone on iOS 10.1 is fine, no iBooks crashes.

I've tried all the usual things: reinstall ios, background apps update and app switcher emptied to free up memory. I also removed all books except those purchased on itunes in case any were corrupt. And still the iBooks app is crashing.

I didn't try the tip below about signing Mac and iPad into and then out of a new iCloud account: I lost the will to live at about that point.

AND THEN I had a bit of a breakthrough. In Settings-->iBooks . I turned off Sync Bookmarks and Notes and also Sync Collections. At the moment the iBooks app seems stable again...continuing to test.... Am wondering if it could be a problem between iCloud storage/sync of books and iOS pre-iOS 10.

Once I'm convinced it's stable I'll use iTunes to add back all my books which were not purchased from Apple. Definitely worth a try given how little effort it is to turn off the two sync settings.

Addendum to my previous post: After further testing, the iBooks app on 9.3.5 is still crashing. So turning sync off hasn't fixed it. It's crashing less often though. All points to a buggy app, I think. I have reported it to Apple, the more of us that do, the more chance they'll fix it.
