Why does the access to the SQLite database takes longer on iOS6?

Having spent some time going through FMDB code in detail, there's nothing there which would account for those sorts of delays. FMDB is a pretty thin wrapper, and almost certainly is not accountable for the behavior. There are also enough SQLite/FMDB users out there, I'll be very surprised if there's actually a SQLite/FMDB related problem in iOS 6.

I would have thought that we would have heard a lot about it by now if there was.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
