How To Manage Session?

[deepak_chrome]

Hi all,
I am designing a small game, that play with few images.
When user is in play section there are so many things those are managed by application.

Now i am trying to manage session of application, so that is user press HOME button of iphone and start application again application will prompt to start from previous location or new one.

I can not use "NSUserDefaults" because there are lots of things to manage ,

Suggest me some better way to retrieve back the last state of application.

Write out a file with the data, read it in - and delete - when you reload.

Thanks for your reply, but did not get it properly.
as i understand u are suggesting me to write all data to file then read from it when return and delete so that new file can be write for new state, but
if i write all data to file even then i have to take care of approximately 570 values. Its a small game i need some way to manage the current state of iphone application.

Why's 570 values a problem?
