当按下不同 UITableView 单元格中的另一个播放按钮时，如何自动停止当前播放音频？ - Swift

Question

I am a swift beginner currently working on my first iOS app.

I have a TableViewController which has several cells and each cell contains a play button. When a few play buttons are pressed, a few different audios are played at the same time, but I would like to stop a currently playing audio when another playing play button is pressed.

Here are the sample codes I created.

Please give me an advice. Thank you so much!

Answer 1

The problem is that every single cell has its own independent player. You want just one player, so that you can stop it and start a new sound. For example, make the one player a property of the view controller. Every cell can see it but there is just one.

Answer 2

create an extension for AVPlayer because AVPlayer does not own condition for playing. extension given below.

extension AVPlayer {
    var isPlaying: Bool {
        return rate != 0 && error == nil
    }
}

use it while tap on play like this.

if player?.isPlaying == true {
   player?.pause()
   player?.seek(to: CMTime(seconds: 0, preferredTimescale: 60))
}
//set up you audio file to player
player?.play()
