迅速。 AVPlayer。歌曲播放完毕后如何追踪？

问题描述

在Swift中用AVPlayer播放歌曲的东方方式是什么？

What is the east way to track when song finished playing with AVPlayer in Swift?

是否有任何在avplayer播放完成后调用的功能，或者我应该结合使用具有avplayer类引用的计时器？

Is there any function which is called when avplayer finished playing, or I should combine timer with avplayer class references?

推荐答案

这样的工作原理：

func play(url: NSURL) {
    let item = AVPlayerItem(URL: url)

    NSNotificationCenter.defaultCenter().addObserver(self, selector: "playerDidFinishPlaying:", name: AVPlayerItemDidPlayToEndTimeNotification, object: item)

    let player = AVPlayer(playerItem: item)
    player.play()
}

func playerDidFinishPlaying(note: NSNotification) {
    // Your code here
}

完成后不要忘记删除观察者（或 deinit ）！

Don't forget to remove the observer when you're done (or in deinit)!
