对于符合UIAccessibility和VoiceOver的个人应用程序，我需要更改UISearchBar中的明文按钮（灰色十字）的UIAccessibilty标签。
我不知道如何访问这个元素。
我试着

class ViewController: UIViewController, UISearchBarDelegate
{
  @IBOutlet weak var searchBar: UISearchBar!

  weak var btnCancel: UIButton?

  override func viewDidLoad()
  {
    super.viewDidLoad()

    for subView in searchBar.subviews
    {
      for subSubView in subView.subviews
      {
        if subSubView.isKindOfClass(UIButton)
        {
          btnCancel = subSubView as? UIButton

          btnCancel?.isAccessibilityElement = true

          btnCancel?.accessibilityLabel =  NSLocalizedString("Clear Text", comment: "")
        }
      }
    }
  }
}

我在viewDidLoad上试了一下;searchBar textDidChange ;searchBarTextDidBeginEditing ;
我从来没找到什么纽扣
欢迎你的帮助

解决方案：

@IBOutlet weak var searchBar: UISearchBar!

  override func viewDidLoad()
  {
    super.viewDidLoad()

    for subView in searchBar.subviews
    {
      for sView in subView.subviews
      {
        if let textField = sView as? UITextField,
           let clearButton = textField.valueForKey("clearButton") as? UIButton
        {
          clearButton.isAccessibilityElement = true

          clearButton.accessibilityLabel =  NSLocalizedString("Clear Text", comment: "")
        }
      }
    }
  }

如果let searchTextField = self.searchBar.value（forKey：“searchField”）作为？UITextField，让clearButton = searchTextField.value（forKey：“clearButton”）as？UIButton { clearButton.isAccessibilityElement = true clearButton.tintColor = .red clearButton.accessibilityLabel = NSLocalizedString（“Clear Button accessibility labe;“，评论：“”）}
