UIApplicationDidEnterBackgroundNotification delivered after entering foreground

Question

I register my VC for UIApplicationDidEnterBackgroundNotification

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(applicationDidEnterBackgroundNotification:) name:UIApplicationDidEnterBackgroundNotification object:nil];

However the notification gets triggered when the app enters foreground, not when it entered background

I assume

that the notification callback happens in next run loop, however, when the app enters background, this next runloop is executed when the app enters foreground

Is there any workaround for this to act really on Entering background?

allright, but there is nothing special on the relevant code as registering for the notification — Peter Lapisu, Dec 20 '14 at 16:39
I use that notification in several classes and in every case the selector is called as the app enters the background. — rmaddy, Dec 20 '14 at 16:59

You could try using the UIApplicationWillResignActiveNotification notification instead, that's when it's about to move to the background. Otherwise, I could answer you better about why it's not getting called until the app becomes active if you add some of your code to the question.
