Adjust tableView height when keyboard appears

[link60]

Hi!
I created a page containing a searchBar and a tableView.
When the keyboard appears, the page goes up and the top comes out of the screen.
I have tried several things, but I am unable to reduce the size of the tableView so that the search bar stays visible.

Here is my code, simplified, to use and try as is:

import UIKit
import BLTNBoard

class HistoricPage: FeedbackPageBLTNItem {
	
	fileprivate var tableView: UITableView?
	fileprivate var searchBar: UISearchBar?
	
	fileprivate var numberOfItems: Int = 20
	
	override func tearDown() {
		super.tearDown()
		tableView?.dataSource = nil
		tableView?.delegate = nil
		searchBar?.delegate = nil
	}
	
	override func makeViewsUnderTitle(with interfaceBuilder: BLTNInterfaceBuilder) -> [UIView]? {
		let stack = interfaceBuilder.makeGroupStack(spacing: 0)
		stack.alignment = .fill
		stack.distribution = .fill
		
		let searchBar = UISearchBar(frame: .zero)
		searchBar.searchBarStyle = .minimal
		let searchBarWrapper = interfaceBuilder.wrapView(searchBar, width: nil, height: nil, position: .pinnedToEdges)
		self.searchBar = searchBar
		
		let tableView = UITableView(frame: .zero, style: .plain)
		tableView.register(UITableViewCell.self, forCellReuseIdentifier: "CellIdentifier")
		tableView.rowHeight = 38
		let tableWrapper = interfaceBuilder.wrapView(tableView, width: nil, height: NSNumber(value: numberOfItems * Int(tableView.rowHeight)), position: .pinnedToEdges)
		self.tableView = tableView
		
		tableView.dataSource = self
		tableView.delegate = self
		searchBar.delegate = self
		
		stack.addArrangedSubview(searchBarWrapper)
		stack.addArrangedSubview(tableWrapper)
		return [stack]
	}
}

extension HistoricPage: UITableViewDataSource, UITableViewDelegate {
	
	func numberOfSections(in tableView: UITableView) -> Int {
		return 1
	}
	
	func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
		return numberOfItems
	}
	
	func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
		let cell = tableView.dequeueReusableCell(withIdentifier: "CellIdentifier", for: indexPath)
		cell.textLabel?.text = String(indexPath.row+1)
		return cell
	}
	
	func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
		self.searchBar?.resignFirstResponder()
	}
}

extension HistoricPage: UISearchBarDelegate {
	
	func searchBarTextDidBeginEditing(_ searchBar: UISearchBar) {
		// Something to do here to resize tableView/tableWrapper?
	}
	
	func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
		if let text = searchBar.text, let numberOfItems = Int(text) {
			tableView?.setContentOffset(.zero, animated: true) // scroll to top
			self.numberOfItems = numberOfItems
			self.tableView?.reloadData()
			// Something to do here to resize tableView/tableWrapper according to number of items?
		}
	}
}

Thanks for the help anyone can give me 🙏

I finally found a solution that suits me:

page.shouldRespondToKeyboardChanges = false

and basically :

    override func onDisplay() {
        super.onDisplay()
        NotificationCenter.default.addObserver(self, selector: #selector(onKeyboardShow), name: UIResponder.keyboardWillShowNotification, object: nil)
        NotificationCenter.default.addObserver(self, selector: #selector(onKeyboardHide), name: UIResponder.keyboardWillHideNotification, object: nil)
    }
    
    @objc func onKeyboardShow(notification: NSNotification) {
        if let keyboardHeight = (notification.userInfo?[UIResponder.keyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue.height {
            self.tableView?.contentInset = UIEdgeInsets(top: 0, left: 0, bottom: keyboardHeight, right: 0)
        }
    }
    
    @objc func onKeyboardHide(notification: NSNotification) {
        UIView.animate(withDuration: 0.2, animations: {
            self.tableView?.contentInset = UIEdgeInsets(top: 0, left: 0, bottom: 88, right: 0)
        })
    }
