我将AVFoundation.framework添加到了我的项目中.在我的项目导航器中,我添加了文件"Horn.mp3",这是1秒钟的声音.

当按下按钮(带有喇叭的图像)时,声音应该播放,标签也应该改变它的文本.

标签正在改变它的文字,但声音没有播放.

这是我的代码:

import UIKit
import AVFoundation

class ViewController: UIViewController {

    @IBAction func hornButtonPressed(_ sender: Any) {
        playSound()
        hornLabel.text = "Toet!!!"
    }

    @IBOutlet weak var hornLabel: UILabel!

    func playSound(){
        var player: AVAudioPlayer?
        let sound = Bundle.main.url(forResource: "Horn", withExtension: "mp3")
        do {
            player = try AVAudioPlayer(contentsOf: sound!)
            guard let player = player else { return }
            player.prepareToPlay()
            player.play()
        } catch let error {
            print(error.localizedDescription)
        }

    }

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, …
