UITABBAR可访问性iOS

Question

[q]可以 uiAcceSsibilityTraits.tabbars.tabbar 仅适用于uitabbar？有什么方法可以使Uiviews具有tabar uiaccessibilitytraits？

在Uitabbar中与Uitabbaritems一起工作。

// This works. No problem
let first = UITabBarItem(title: "firstTab", image: UIImage(systemName: "chart.line.uptrend.xyaxis"), selectedImage: UIImage(systemName: "chart.line.uptrend.xyaxis"))
let second = UITabBarItem(title: "secondTab", image: UIImage(systemName: "arrow.left.and.right.square"), selectedImage: UIImage(systemName: "arrow.left.and.right.square"))

let tabBar = UITabBar()
tabBar.setItems([first, second], animated: true)
view.addSubview(tabBar)
tabBar.translatesAutoresizingMaskIntoConstraints = false
NSLayoutConstraint.activate([
    tabBar.leadingAnchor.constraint(equalTo: view.leadingAnchor),
    tabBar.trailingAnchor.constraint(equalTo: view.trailingAnchor),
    tabBar.bottomAnchor.constraint(equalTo: view.bottomAnchor),
    tabBar.heightAnchor.constraint(equalToConstant: 100)
])

tabBar.isAccessibilityElement = false
tabBar.accessibilityTraits = .tabBar

但是，我的 tabar和tabbaritems应该是uiview 不是uitabbar和uitabbaritems。而且这行不通。

// Doesn't work
let label1 = UILabel()
let label2 = UILabel()
label1.text = "first"
label2.text = "second"

let stackView = UIStackView(arrangedSubviews: [label1, label2])
view.addSubview(stackView)
stackView.translatesAutoresizingMaskIntoConstraints = false
NSLayoutConstraint.activate([
  stackView.leadingAnchor.constraint(equalTo: view.leadingAnchor),
  stackView.trailingAnchor.constraint(equalTo: view.trailingAnchor),
  stackView.bottomAnchor.constraint(equalTo: view.bottomAnchor)
])
stackView.backgroundColor = .cyan
stackView.axis = .horizontal

stackView.isAccessibilityElement = false
stackView.accessibilityTraits = .tabBar
