Playing a sound with AVAudioPlayer
Here is some example code:
下面是一些示例代码：
import AVFoundation
var audioPlayer: AVAudioPlayer?
if let path = NSBundle.mainBundle().pathForResource("mysound", ofType: "aiff") {
audioPlayer = AVAudioPlayer(contentsOfURL: NSURL(fileURLWithPath: path), fileTypeHint: "aiff", error: nil)
if let sound = audioPlayer {
sound.prepareToPlay()
sound.play()
}
}

First drag your sound to your project and choose to copy for your destination if needed and check "add to target" to your app. Create a function to play your sound and you need also to add import AVFoundation at the beginning of your code as bellow:
首先将您的声音拖到您的项目中，并根据需要选择复制到您的目的地，然后选中“添加到目标”到您的应用程序。创建一个函数来播放你的声音，你还需要在代码的开头添加 import AVFoundation ，如下所示：
import AVFoundation
let beepSoundURL = NSBundle.mainBundle().URLForResource("beep", withExtension: "aif")!
var beepPlayer = AVAudioPlayer()
func playMySound(){
beepPlayer = AVAudioPlayer(contentsOfURL: beepSoundURL, error: nil)
beepPlayer.prepareToPlay()
beepPlayer.play()
}
@IBAction func pistolButton(sender: AnyObject) {
playMySound()
}

Swift 3
斯威夫特 3
the syntax is now as follows:
语法如下：
import UIKit
import AVFoundation
class ViewController: UIViewController {
var audioPlayer = AVAudioPlayer()
override func viewDidLoad() {
super.viewDidLoad()
// address of the music file
let music = Bundle.main.path(forResource: "Music", ofType: "mp3")
do {
audioPlayer = try AVAudioPlayer(contentsOf: URL(fileURLWithPath: music! ))
}
catch{
print(error)
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
@IBAction func play(_ sender: AnyObject) {
audioPlayer.play()
}
@IBAction func stop(_ sender: AnyObject) {
audioPlayer.stop()
}
}
