在AVAudioPlayer中检测播放结束 [英] Detecting end of the playback in AVAudioPlayer

问题描述

我有一些短的.mp3声音，我将它们存储在数组中，并希望连续播放它们.有什么方法可以检测AVAudioPlayer何时停止播放，以便我可以调用完成处理程序并播放下一个声音?我知道有一个代表，但是我正在使用Playground和SKScene.

I've got couple of short .mp3 sounds which I'm storing in the array and would like to play them consecutively. Is there any way to detect when AVAudioPlayer stopped playing so that I could call a completion handler and play next sound? I know that there is a delegate for that but I'm using Playground and SKScene.

Hellp @codddeer123,

AVAudioPlayer包含AVAudioPlayerDelegte方法，该方法在音频播放完成时被调用.

AVAudioPlayer contains AVAudioPlayerDelegte method which is called on audio playing completed.

我已将其实现为班级的扩展，您可以随心所欲.

I have implemented it as extension of my class, you can do as you likes.

extension MyViewController: AVAudioPlayerDelegate {

    func audioPlayerDidFinishPlaying(_ player: AVAudioPlayer, successfully flag: Bool) {
        if flag {
            // After successfully finish song playing will stop audio player and remove from memory
            print("Audio player finished playing")
            self.audioPlayer?.stop()
            self.audioPlayer = nil
            // Write code to play next audio.
        }
    }
}
