You can follow similar concept. When user logging in put some thing as NSUserDefaults like

[[NSUserDefaults standardUserDefaults] setValue:@"ABCDEFGHIJK" forKey:@"SessionKey"];

and in application delegate there is one method called

(void) applicationDidEnterBackground:(UIApplication *)application

which will be called when application is going in background. Just remove that set variable for the sessionkey. And while application is again being launched just check the condition and redirect user to desired screen.

Hope this helps.
