iOS 11 prefersLargeTitles not updating until scroll

Question

I implemented a basic UIViewController with a UITableView that\'s wrapped in a UINavigationController. I set prefersLargeTitles to true:

override fu         


        

Answer 1

That does seem like a weird behavior at first, but try setting the navigationItem.largeTitleDisplayMode to always. The default is automatic - and it's not defined how that works in the docs.
