ios - 音频 - 快进 30 秒

Question

我有一个音频播放器，可以播放从 Core Date 检索到的音频。播放和暂停工作正常。我正在尝试实现“向前跳转 30 秒”按钮，并寻求有关我将如何实现的任何指示。

“播放/暂停”按钮的代码

@IBAction func playPressed(sender: AnyObject) { 

    let play = UIImage(named: "play")
    let pause = UIImage(named: "pause")
    if audioPlayer.playing {
        pauseAudioPlayer()
        audioPlayer.playing ? "\(playButton.setImage( pause, forState: UIControlState.Normal))" : "\(playButton.setImage(play , forState: UIControlState.Normal))"

    }else{
        playAudio()
        audioPlayer.playing ? "\(playButton.setImage( pause, forState: UIControlState.Normal))" : "\(playButton.setImage(play , forState: UIControlState.Normal))"
    }

}

Answer 1

在 swift 3 中:

player.play()
player.currentTime=60

单位是秒 根本不需要停下来
