Add toolbar item to the floating keyboard assistant bar in iPadOS? (not the usual keyboard toolbar)

Question

This is a iPadOS hardware keyboard assistant bar related question.

I want to do this (app is iA Writer, so it's definitely not a private API)

However, when I try to use

.toolbar {
         ToolbarItem(placement: .keyboard) {
// Picker, Button, etc..
            }
}

It shows up in an older-style, full-screen bar (which works for iOS, but really out of place for iPadOS).

I searched all over the internet and could not find what I need to do to place toolbar items into the keyboard assistant bar. I might be searching for the wrong terms.

Does anyone know how this is accomplished? iA Writer has done this, the lightning and search icon open up custom functions/menus, so there must be a public API for it.

Appreciate your help!

Answer 1

this code is working for me

class MyTextViewController: UIViewController, UITextViewDelegate {
    let textView = UITextView()

    override func viewDidLoad() {
        super.viewDidLoad()
        textView.frame = view.bounds
        textView.delegate = self
        view.addSubview(textView)

        configureKeyboardShortcutBar()
    }

    func configureKeyboardShortcutBar() {
        let inputAssistant = textView.inputAssistantItem
        inputAssistant.leadingBarButtonGroups = [UIBarButtonItemGroup(barButtonItems: [createButton(title: "Expense"), createButton(title: "Income")], representativeItem: nil)]
        inputAssistant.trailingBarButtonGroups = [UIBarButtonItemGroup(barButtonItems: [createButton(title: "Notes")], representativeItem: nil)]
    }

    func createButton(title: String) -> UIBarButtonItem {
        return UIBarButtonItem(title: title, style: .plain, target: self, action: #selector(toolbarButtonTapped(_:)))
    }

    @objc func toolbarButtonTapped(_ sender: UIBarButtonItem) {
        print("\(sender.title ?? "") tapped")
    }
}
