Issue related to child view controllers

[bernikovich]

Hello.

I have issue with custom controllers hierarchy. My VCs stack looks like this:

Code in blue VC:

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
    
    static UIScrollView *scrollView;
    if (!scrollView) {
        for (UIView *view in self.view.subviews) {
            if ([view isKindOfClass:[UIScrollView class]]) {
                scrollView = (UIScrollView *)view;
                break;
            }
        }
        scrollView.contentSize = CGSizeMake(CGRectGetWidth(scrollView.frame), 2000);
        UIView *content = [UIView new];
        content.backgroundColor = [UIColor redColor];
        content.frame = CGRectMake(0, 0, scrollView.contentSize.width, scrollView.contentSize.height);
        [scrollView addSubview:content];
    }
    
    if (!self.isShyNavBarManagerPresent) {
        TLYShyNavBarManager *scrollManager = [TLYShyNavBarManager new];
        scrollManager.scrollView = scrollView;
        [self setShyNavBarManager:scrollManager viewController:self.parentViewController];
    }
}

I have already tried (with no luck):

• Replace [self setShyNavBarManager:scrollManager viewController:self.parentViewController]; with [self setShyNavBarManager:scrollManager viewController:self];.

You can check sample project, try to push view controller (press bar button item) and than go back: https://github.com/bernikowich/TLYShyNavBarChildControllerIssue
