ios - 如何在听到音乐时使用 AVAudioplayer 快进？

Question

我让它快进了，但我想在快进时听到音乐。我怎样才能做到这一点？这是我的代码:

if node.name == "left" {

            var time = musicPlayer.currentTime
            time += 1.0
            musicPlayer.enableRate = true
            musicPlayer.rate = 2.0


            if time > musicPlayer.duration {

            } else {
                musicPlayer.currentTime = time
     }
}

Answer 1

看看 rate AVAudioPlayer

上的属性

This property’s default value of 1.0 provides normal playback rate. The available range is from 0.5 for half-speed playback through 2.0 for double-speed playback.

To set an audio player’s playback rate, you must first enable rate adjustment as described in the enableRate property description.

您可以在按下按钮时更改一定时间的速率以模拟快进
