swift - 视频在 tvOS 中播放完后如何播放广告？

Question

因此，当您单击缩略图时我可以播放视频，但如果我将广告附加到它，广告将在视频上播放。之后如何等待播放广告？

func playVideo(){

    player = AVPlayer(URL: NSURL(string: String(vid))!)
    player?.play()

    if(ALInterstitialAd.isReadyForDisplay()){
        ALInterstitialAd.show()
    }
}

Answer 1

您是否尝试注册 AVPlayerItemDidPlayToEndTimeNotification？

只需添加

NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(YourViewController.itemDidFinishPlaying(_:)), name: AVPlayerItemDidPlayToEndTimeNotification, object: nil)

当您播放视频并实现 itemDidFinishPlaying: 方法时，您需要展示您的广告。像这样:

func playVideo(){
    player = AVPlayer(URL: NSURL(string: String(vid))!)
    player?.play()
    NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(YourViewController.itemDidFinishPlaying(_:)), name: AVPlayerItemDidPlayToEndTimeNotification, object: nil)
}

func itemDidFinishPlaying(notification : NSNotification){
    if(ALInterstitialAd.isReadyForDisplay()){
        ALInterstitialAd.show()
    }
    NSNotificationCenter.defaultCenter().removeObserver(self, name: AVPlayerItemDidPlayToEndTimeNotification, object: nil)
}
