Hi all,

My view controller needs to know when it is poped out of the navigation controller stack, so that it can retain itself, wait and release itself later with another notification.

I intend to do like that when the view is sent dealloc message:

- (void)dealloc {
    if (self.isPerformingSomeTask) {
        self.isPopedOut = YES;
        [self retain];
        return;
    }
    [super dealloc];
}

But I think this is not a good solution? Any idea?
