如何在 AVQueuePlayer 的项目之间插入暂停？

Question

我正在使用 AVQueuePlayer 播放一批音频文件。我想在项目之间插入一个暂停。知道怎么做吗？

这里是将项目添加到队列的方法：

func addItemToAudioQueue (file:String, last:Bool) {
        let urlPath = Bundle.main.path(forResource: file, ofType: "mp3")
        let fileURL = NSURL(fileURLWithPath:urlPath!)
        let playerItem = AVPlayerItem(url:fileURL as URL)
        if last {
            NotificationCenter.default.addObserver(self, selector: #selector(self.playerDidFinishPlaying(sender:)), name: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: playerItem)
        }
        queuePlayer.insert(playerItem, after: nil)
    }

Answer 1

为名为 AVPlayerItemDidPlayToEndTimeNotification 的 notification 添加一个 observer，每次播放完 AVPlayerItem 都会触发, 即

NotificationCenter.default.addObserver(self, selector: #selector(playerEndedPlaying), name: Notification.Name("AVPlayerItemDidPlayToEndTimeNotification"), object: nil)

AVPlayerItemDidPlayToEndTimeNotification

A notification that's posted when the item has played to its end time.

接下来，当 playerEndedPlaying 方法在 notification 触发后被调用时，pause() 最初是 AVQueuePlayer，然后 play() 在 5 之后再次调用像这样秒，

@objc func playerEndedPlaying(_ notification: Notification) {
    self.player?.pause()

    DispatchQueue.main.asyncAfter(deadline: .now() + 5.0) {[weak self] in
        self?.player?.play()
    }
}
