是否有可能发挥时，图像-5被称为在下面的图像阵列如何使用Swift 3.0播放附加到Image Array的声音？

下面是完整的代码，包括建立AVAudioPlayer

ImageArray和你建议的代码声音：

import UIKit 
import AVFoundation 
class ViewController: UIViewController { 
    var player:AVAudioPlayer = AVAudioPlayer() 
    @IBOutlet weak var imageView: UIImageView! 
    override func viewDidLoad() { 
     super.viewDidLoad()  
    var imagesName = ["Image-1.png","Image-2.png","Image-3.png","Image-4.png","Image-5.png","Image-6.png","Image-7.png","Image-8.png","Image-9.png","Image-10.png"] 
      var images = [UIImage]() 
      for i in 0..<imagesName.count{ 
       images.append(UIImage(named: imagesName[i])!) 
      } 
      imageView.animationImages = images 
      imageView.animationDuration = 0.5 
      imageView.animationRepeatCount = 1 
      imageView.startAnimating() 
      do 
    { 
     let audioPath = Bundle.main.path(forResource: "song", ofType: "mp3") 
     try player = AVAudioPlayer(contentsOf: NSURL(fileURLWithPath: audioPath!) as URL) 
    } 
    catch 
    { 
     //ERROR 
    } 
    let whichImage: Int = 5 
    let when = DispatchTime.now() + imageView.animationDuration * TimeInterval(whichImage-1) 
    DispatchQueue.main.asyncAfter(deadline: when) { 
     self.player.play() 
     // Play sound here 
    }

回答：

正如你间隔是固定的，你还挺已经知道当图像-5将被解雇，那么试试这个：

let whichImage: Int = 5 
let when = DispatchTime.now() + imageView.animationDuration * TimeInterval(whichImage-1) 
DispatchQueue.main.asyncAfter(deadline: when) { 
    // Play sound here 
}
