searchBar does not hide after pushing another view controller

it fixes the issue One of these two UISearchBarDelegate delegate methods should fix your problem
code :
- (BOOL)searchBarShouldEndEditing:(UISearchBar *)searchBar {
return YES;
}

- (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar {
[self.searchBar resignFirstResponder];
}

it fixes the issue @alexbumbu is right the best way is not to over-combine with UIPageViewController and use separate UINavigationControllers for every page stack flow.
That was my choice

should help you out One of the solutions is to add your searchBar and your label as subViews to a UIView. Then set this UIView as the TableHeaderView. My working sample looks like this:

hop of those help? My guess would be that it's some sort of race condition to do with pushing while transitioning to a different size. Probably the updateConstraints/needsLayout flag is NO when the transition to the new size is complete (i.e. it already thinks it's fully finished laying out it's view after the push is complete but the rotation hasn't completed). I would consider this an Apple Bug and would report it if you haven't already.
As a workaround you could use a subclass of UINavigationController and implement viewWillTransitionToSize:withTransitionCoordinator: then if needed throw an extra [self.view setNeedsLayout] or [self.view setNeedsUpdateConstraints] in the completion block of coordinator animateAlongsideTransition:completion:
code :
- (void)viewWillTransitionToSize:(CGSize)size withTransitionCoordinator:(id<UIViewControllerTransitionCoordinator>)coordinator {
    [coordinator animateAlongsideTransition:^(id<UIViewControllerTransitionCoordinatorContext>  _Nonnull context) {
    } completion:^(id<UIViewControllerTransitionCoordinatorContext>  _Nonnull context) {
        UIView *topView = [self.topViewController view];
        // we should only need an additional layout if the topView's size doesn't match the size
        // we're transitioning to (otherwise it should have already beend layed out properly)
        BOOL needsAdditionalLayout = topView && CGSizeEqualToSize(topView.frame.size, size) == NO;
        if (needsAdditionalLayout) {
            // either of these two should do the trick
            [self.view setNeedsUpdateConstraints];
            // [self.view setNeedsLayout];
        }
    }];
}

this will help Looks like there still ins't a way to hide the left/right buttons while pushing using NavigatorIOS.
A small hack that I use is setting the leftButtonTitle to a whitespace.

This might help you Via experimentation, I have discovered that if you delay assigning the search controller to the navigation item until viewWillLayoutSubviews or viewDidLayoutSubviews, the search controller starts out hidden, as desired. However, this if you do this on iOS 12 or earlier, the search controller will not be revealed when scrolling down.
I ended up doing the following with a messy version check, which is working for me:
code :
override func viewDidLoad() {
    super.viewDidLoad()

    searchController = /* make search controller... */

    if #available(iOS 13, *) {
        // Attaching the search controller at this time on iOS 13 results in the
        // search bar being initially visible, so assign it later
    }
    else {
        navigationItem.searchController = searchController
    }
}

override func viewWillLayoutSubviews() {
    super.viewWillLayoutSubviews()
    navigationItem.searchController = searchController
}
