how to detect idle user in iphone-sdk

In my Application I want to call Logout Function if user is idle for certain amount of time how to accomplish

this answer doesn't work for me iPhone: Detecting user inactivity/idle time since last screen touch if i subclass my app delegate class from UIApplication and implement 

- (void)sendEvent:(UIEvent *)event

It gives me error 

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'There can only be one UIApplication instance.'

I can't find the other instance of UIApplication in my application

so far i have done

instead of 

@interface IdleAppDelegate : NSObject <UIApplicationDelegate> {

I have changed it to 

@interface IdleAppDelegate : UIApplication<UIApplicationDelegate> {

and in the main instead of 

 int retVal = UIApplicationMain(argc, argv, nil, nil);

I've changed it to 

int retVal = UIApplicationMain(argc, argv, @"IdleAppDelegate", @"IdleAppDelegate");

Is there anything remaining to do?

I'm getting the above error... am I missing something...?

Please Help

Thanks

Your application class is also an application delegate class - that's bad. UIApplicationMain() will create an instance of your custom application subclass, which will then try to an instance of its delegate - which is also an instance of your custom application subclass. You should separate these concerns - yes your custom app subclass needs to subclass UIApplication, but your app delegate should be a separate class that subclasses NSObject.

Try this out

-(void)applicationWillResignActive:(UIApplication *)application

{
    NSLog(@"Application not Active");
    // FETCH THE CURRENT TIME 
}
