在滑动时保持 TabBar 大标题 swift

Question

I have a UIViewController which holds a UITableView and also have a navigation bar with a large title. Whenever I scroll down through the table view, the large title disappears and becomes a small header. How can I maintain the large title (make it static/sticky) when I scroll through.

I added a picture of my screen before the swipe , in the middle of a swipe , and after the swipe.

I want to maintain the large title seen in the before the swipe image even after the swipe occurs.

The code I currently have in terms of the navigation bar (for the large header and transparency) is as follows

class OneChallengeViewController: UIViewController {

@IBOutlet weak var tableView: UITableView!
let productCellId = "TableViewCell1TableViewCell"
var products = [ProductDto]()

override func viewDidLoad() {
 super.viewDidLoad()
 
 
 navigationController?.navigationBar.prefersLargeTitles = true
 navigationItem.title = "Challenges"
 navigationController?.navigationBar.barStyle = .default
 navigationController?.navigationBar.largeTitleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.white]
 navigationController?.navigationItem.largeTitleDisplayMode = .always



 }

Answer 1

The title will collapse on scroll as long as the root view is scrollable, ie is a scrollView or a view which embeds a UIScrollView .

To achieve what you want in the particular case you'd need to add a dummy view ahead of your tableView in the view hierarchy.

I've found your question while searching how to achieve the opposite
