how to use session in iphone programming?
<p>I made an iphone story book application.
Suppose any user read story book and at half of the story book he/she close the apps.
when he/she want to read again this application at a time ask for continue or start again.
This is possible by using session but i don't know how to use session in iphone sdk.
So, please help me about this problem.</p>

<p>Thanks!</p>
