Question

如何在swift3中使用此代码创建函数？

我有一个按下按钮然后播放此声音＆＃34;按下＃34;

有很多按钮时如何简化？我不想将所有代码添加到每个按钮。

 var myAudio = AVAudioPlayer()
// Add sound
        do {
            try myAudio = AVAudioPlayer(contentsOf: NSURL(fileURLWithPath:
                Bundle.main.path(forResource: "push", ofType: "mp3")!) as URL)
        } catch {
            NSLog("No file!")

        }
//call the sound
myAudio.play()

我做了这个改变

func play(name : String){

        do {
            try myAudio = AVAudioPlayer(contentsOf: NSURL(fileURLWithPath:
                Bundle.main.path(forResource: name, ofType: "mp3")!) as URL)

        } catch {
            NSLog("No file!")

        }


    }

    @IBAction func buttonFirst(_ sender: UIButton) {

        play(name: "push")
        myAudio.play()

    }

    @IBAction func buttonSecond(_ sender: UIButton) {
        play(name: "second")
        myAudio.play()
    }

我得到了这个输出：
2017-07-25 16:13:23.270349 + 0100声音[1728：933024] [aqme] 254：AQDefaultDevice（173）：跳过输入流0 0 0x0

这是一个问题吗？

您可以按以下方式使用

    var myAudio : AVAudioPlayer?

func playSound(){
    let path = Bundle.main.path(forResource: "push", ofType:"mp3")!
    let url = URL(fileURLWithPath: path)

    do {
        let sound = try AVAudioPlayer(contentsOf: url)
        self.myAudio = sound
        sound.numberOfLoops = 1
        sound.prepareToPlay()
        sound.play()
    } catch {
        print("error loading file")
        // couldn't load file :(
    }
}

此外，您可以使用SwiftySound让您轻松在Swift 3中播放声音。例如

Sound.play(file: "push.mp3")

从代码创建一个函数
