如何捕获 AVPlayer 的 keydown 事件？

Question

我正在用macOS下的AVkit编写一个视频播放器，AVPlayer可以响应键盘事件，例如，space键向下到pause/play视频，左箭头键向下将视频后移。我想捕获keydown事件，这样我就可以对AVPlayer做更多的控制，怎么办？
以下是我的示例代码：

import SwiftUI
import AVKit
import AVFoundation

public class VideoItem: ObservableObject {
    @Published var player: AVPlayer = AVPlayer()
    @Published var playerItem: AVPlayerItem?

    func open(_ url: URL) {
        let asset = AVAsset(url: url)

        let playerItem = AVPlayerItem(asset: asset)
        self.playerItem = playerItem

        player.replaceCurrentItem(with: playerItem)


    }
}

public struct PlayerView: NSViewRepresentable {
    @Binding var player: AVPlayer

    var titles:[Title] = []
    public init(player:Binding<AVPlayer>,currentSeconds:Binding<Double>,subtitleFile:Binding<String>,currentTitle:Binding<Title?>)
    {
        self._player = player


    }

    public func updateNSView(_ NSView: NSView, context: NSViewRepresentableContext<PlayerView>) {
        guard let view = NSView as? AVPlayerView else {
            debugPrint("unexpected view")
            return
        }
      //  status = player.timeControlStatus.rawValue

        view.player = player


    }

    public func makeNSView(context: Context) -> NSView {
        let av = AVPlayerView(frame: .zero)

        return av
    }


}

我有一个解决方案，可以捕获按键事件，我们可以从 AVPlayerView 创建一个子类并覆盖它的按键事件。
