在macOS上播放声音

Question

我喜欢在我的应用中播放声音.我发现了很多例子,也可以在Swift 3上编译和运行它们.但是它们总是用于iOS.当在我的应用程序中使用此代码时,AVAudioSession保持未定义.我需要做什么？OSX有什么不同之处吗？

import AVFoundation
...
    var audioPlayer = AVAudioPlayer()
    func PlaySound( ) {
        let alertSound = URL(fileURLWithPath: Bundle.main.path(forResource: "Sound", ofType: "mp3")!)
        do {
            try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
        } catch _ {
        }
        do {
            try AVAudioSession.sharedInstance().setActive(true)
        } catch _ {
        }
        do {
            audioPlayer = try AVAudioPlayer(contentsOf: alertSound)
        } catch _{
        }
        audioPlayer.prepareToPlay()
        audioPlayer.play()
    }

Answer 1

Swift 3/4/4.2/5 - 最简单的解决方案:

NSSound(named: "customSound")?.play()

Answer 2

我已经将以下函数与Swift 3和Cocoa项目结合使用.

import AVFoundation

func playSound(file:String, ext:String) -> Void {
    let url = Bundle.main.url(forResource: file, withExtension: ext)!
    do {
        let player = try AVAudioPlayer(contentsOf: url)
        player.prepareToPlay()
        player.play()
    } catch let error {
        print(error.localizedDescription)
    }
}

//用法//

playSound(file: "sound", ext: "caf") // where the file name is sound.caf.

在Xcode项目中选择音频文件时,请确保已启用目标成员资格复选框.
