IPhone .sqlite file place

How can I change the place of the 开发者_JAVA百科.sqlite file in my directory structure. Now it is in the Documents, but I want it to be in the Library/Preferences. Can you help me please?

Assuming you have something like this in your code:

[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];

Try replacing NSDocumentDirectory with NSLibraryDirectory.

I am not sure where and if you are allowed to write files there (except by using the sanctioned methods, of course).
