ios - 如何加载和播放音频文件列表

Question

我有两个 View Controller collectionViewChild和imageViewController。我在 imageViewController 中加载图像。现在，在该图像上我有一个按钮，我想在每个图像上播放特定的声音。我知道如何播放单个音频声音，但不知道如何选择特定声音并与所需的图像一起播放。

// collectionViewChild , here i want to display the image in the collectionviewChild



 func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) {
            self.performSegueWithIdentifier("showDetailedImage", sender: self)
    }

    override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?){ if segue.identifier == "showDetailedImage" {
            let indexPaths =           self.collectionViewChild!.indexPathsForSelectedItems()!
            let indexPath = indexPaths[0] as NSIndexPath
            let vc = segue.destinationViewController as! imageViewController
             vc.title = self.tableData[indexPath.row]
            vc.image = images[indexPath.row] as! UIImage
           }}}

//这是ImageViewController

import UIKit
import AVFoundation

class imageViewController: UIViewController {
@IBOutlet weak var imageView03: UIImageView!
    var selMake = UIImage()
  var image = UIImage()
     var audioPlayer = AVAudioPlayer()

// on this button i want to play the specific audio file
@IBAction func soundButton(sender: AnyObject) {
    let soundLocation = NSBundle.mainBundle().pathForResource("2", ofType: ".mp3")
     do {
    self.audioPlayer = try AVAudioPlayer(contentsOfURL: NSURL(fileURLWithPath: soundLocation!))
    try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
    try AVAudioSession.sharedInstance().setActive(true)
    }
    catch {
    print("Something bad happened. Try catching specific errors to narrow things down")
    }
    self.audioPlayer.prepareToPlay()
    self.audioPlayer.play()
    }
    else { print("") }

override func viewDidLoad() {
        self.imageView03.image = self.image
        super.viewDidLoad()
    }

具有多个音频播放器的辅助类不会有帮助吗？我制作了一个简单的音频播放器类，可以轻松扩展为多个轨道。

你可以从 gitHub 获取我的助手 https://github.com/crashoverride777/Swift2-Music-Helper

当按下图像时，您会在按钮方法中播放相应的声音。

Music.sharedInstance.playImage1()
Music.sharedInstance.playImage2()

...

您可以将其与上面的 Mohamed 评论结合起来。
