AVPlayerItemDidPlayToEndTime与applicationDidBecomeActive冲突。

Question

我有一个 AVPlayer 蕴含 UIViewController. 我加了 AVPlayerItemDidPlayToEndTime 通知 UIViewController 这样我就可以重新启动我的 AVPlayer 播放完毕后 currentItem

    NotificationCenter.default.addObserver(self, selector: #selector(playerDidFinishPlaying), name: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object:player.currentItem)

    @objc private func playerDidFinishPlaying(_ notification: Notification) {
        guard let url = URL(string: self.video.alt_content) else { return }

        let item = self.getAssetToPlay(url: url)
        item.seek(to: .zero, toleranceBefore: .zero, toleranceAfter: .zero)
        self.player.replaceCurrentItem(with: item)
        player.play()
    }

    private func getAssetToPlay(url: URL) -> AVPlayerItem {
        let asset = AVURLAsset(url: url)
        let item = AVPlayerItem(asset: asset)
        return item
    }

但这个通知也是从 AppDelegate's applicationDidBecomeActive，比如我的应用从后台来。因此，而不是玩 AVPlayer 从当前时间开始，代码在以下情况下重启播放器 playerDidFinishPlaying.

我需要一种方法，使当应用程序从后台开始播放，它是离开的地方。并在完全完成 currentItem，它重新启动了 AVPlayerItem

所以问题是非常愚蠢的，说实话。這是由於我加入了 Observer 在初始化之前 AVPlayer. 当我修改了代码后，它不再与 applicationDidBecomeActive
