I need your help in clarifying my understanding of the various states of an app. I am going to state my interpretation - but please feel free to correct me.

1) App is launched and running in the foreground: state = UIApplicationStateActive
2) User pushes home button: state = UIApplicationStateBackground (????). 

 Debug stmt in my app shows it to be Active

3) User double-taps Home and kills the app: state = UIApplicationStateInactive

If the value for case 2 is indeed Active, then when is the value set to Background?

My location-based app relies on this values to take appropriate action for the user.

if ( ([UIApplication sharedApplication].applicationState == UIApplicationStateBackground) ||
    ([UIApplication sharedApplication].applicationState == UIApplicationStateInactive)      ) {
    // isInBackground = YES;
    //  ------ UI not available
}
else {
   // isInBackground = NO;
   //   ------ UI is available
}

Regards, Sam.
