ios - AVPlayer中如何处理网络中断

Question

我使用可达性来确定网络更改，但一旦我确定我正在尝试重新加载项目，但它不起作用

// Check if the playback could keep up after a network interruption
private func checkNetworkInterruption() {
    guard
        let item = playerItem,
        !item.isPlaybackLikelyToKeepUp,
        reachability?.connection != .unavailable else { return }

    self.player?.pause()

    // Wait 1 sec to recheck and make sure the reload is needed
    DispatchQueue.main.asyncAfter(deadline: DispatchTime.now() + 1) {
        if !item.isPlaybackLikelyToKeepUp {
            self.reloadItem()
        }
        self.isPlaying ? self.playSong() : self.player?.pause()
    }
}

私有(private) func reloadItem() {
玩家？.replaceCurrentItem(with: nil)
玩家？.replaceCurrentItem(与:playerItem)
}

AVPlayer可以自行处理网络中断，当网络故障时，视频暂停，保持缓冲状态，当网络稳定时，视频恢复。

但如果需要处理网络中断，可以尝试:

private func checkNetworkInterruption() {
    guard
        let item = playerItem,
        !item.isPlaybackLikelyToKeepUp,
        reachability?.connection != .unavailable else { return }

    self.player?.pause()

    // Wait 1 sec to recheck and make sure the reload is needed
    DispatchQueue.main.asyncAfter(deadline: DispatchTime.now() + 1) {
        if !item.isPlaybackLikelyToKeepUp {
            //you can create a new AVItem here 
            player?.replaceCurrentItem(with: item)
        }
        self.isPlaying ? self.playSong() : self.player?.pause()
    }
}
