快速创建和播放声音

Question

所以我想做的就是快速创建并播放声音，当我按下按钮时会播放声音，我知道如何在Objective-C中做到这一点，但是有人知道如何在Swift中做到吗？

对于Objective-C来说是这样的：

NSURL *soundURL = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"mysoundname" ofType:@"wav"]];
AudioServicesCreateSystemSoundID((__bridge CFURLRef)soundURL, &mySound);

然后播放它，我会做：

AudioServicesPlaySystemSound(Explosion);

有人知道我该怎么做吗？

Answer 1

这是我添加到FlappySwift的一些有效的代码：

import SpriteKit
import AVFoundation

class GameScene: SKScene {

    // Grab the path, make sure to add it to your project!
    var coinSound = NSURL(fileURLWithPath: Bundle.main.path(forResource: "coin", ofType: "wav")!)
    var audioPlayer = AVAudioPlayer()

    // Initial setup
    override func didMoveToView(view: SKView) {
        audioPlayer = AVAudioPlayer(contentsOfURL: coinSound, error: nil)
        audioPlayer.prepareToPlay()
    }

    // Trigger the sound effect when the player grabs the coin
    func didBeginContact(contact: SKPhysicsContact!) {
        audioPlayer.play()
    }

}
