为什么可视化调试看不到inputAccessoryView?

Why inputAccessoryView is not visible in visual debugging?

我在这里附上了模拟器截图和调试视图window。 screenshot from xcode view debugger 和 simulator screenshot

如您所见,inputAccessoryView在模拟器中可见,但在可视化调试中不可见,不明白为什么,请帮助:)

inputAccessoryView 的代码:

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        view.backgroundColor = .blue
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    override var inputAccessoryView: UIView? {
        let v = UIView.init(frame: CGRect.init(x: 0, y: 0, width: view.frame.size.width, height: 60))
        v.backgroundColor = .red
        let label = UILabel()
        label.textAlignment = .center
        label.translatesAutoresizingMaskIntoConstraints = false
        v.addSubview(label)
        label.text = "inputAccessoryView"
        label.widthAnchor.constraint(equalToConstant: 250).isActive = true
        label.centerXAnchor.constraint(equalTo: v.centerXAnchor).isActive = true
        label.centerYAnchor.constraint(equalTo: v.centerYAnchor).isActive = true
        return v
    }

    override var canBecomeFirstResponder: Bool {
        return true
    }
}

inputAccessoryView 在另一个名为 UITextEffectsWindow 的 window 上,要使其显示在视图调试器中,您必须 select window 或任何调试导航器选项卡 window 中的子项
