CoreData save does no persist over app lifestyle

Question

Hi,

I got a strange issue. I am inserting a new object into my Core Data database. I can make request over all my datas but when I close the application and launch it again all my datas are gone ... With iPhone 0S 3 I haven't got this problem, but now with iOS 4 ... Someone have an idea?

The answer of Marcus S. Zarra probably is a good hint. iOS4 changed a lot because of multitasking.

For a start, take everything you do in -applicationWillTerminate: and copy it also into -applicationDidEnterBackground:. See if that helps. – Thomas Müller Jun 28 at 23:16
