- (void)viewDidLoad {
    [super viewDidLoad];
    [self scrollView].scrollsToTop = NO;
    [self scrollView].delegate = self;
...
}

- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView
{
    [super scrollViewDidEndDecelerating:scrollView];
    [self setScrollsToTopForViewControllersTopViewControllerView:self.previousPageViewController];
    [self setScrollsToTopForViewControllersTopViewControllerView:self.currentPageViewController];
    [self setScrollsToTopForViewControllersTopViewControllerView:self.nextPageViewController];
}

- (void)setScrollsToTopForViewControllersTopViewControllerView:(UIViewController*)viewController
{
    [self viewControllersTopViewControllerView:viewController scrollsToTop:(viewController == self.currentPageViewController)];
}

- (void)viewControllersTopViewControllerView:(UIViewController*)viewController scrollsToTop:(BOOL)scrollsToTop
{
    if ([viewController isKindOfClass:[UINavigationController class]]) {
        UINavigationController *navigationController = (UINavigationController*)viewController;
        if ([navigationController.topViewController.view isKindOfClass:[UIScrollView class]]) {
            ((UIScrollView*)navigationController.topViewController.view).scrollsToTop = scrollsToTop;
        }
    }
}
