Just a wild guess --- are you saving atomically ? When writing NSData
objects, as one
example, you can write to file atomically, in which case the object is written
to a backup file
which is renamed if the write succeeds. The idea is that the write either
succeeds or fails,
but nothing in between that would leave a corrupted file . . .
