为每个按钮添加声音

我正在制作应用程序以从用户那里获取名称，然后选择一个缩略图（它会播放声音）。问题是我不能让它为每个按钮播放不同的声音。它所扮演的是最后一个我把价值锁定的人（在这种情况下，复仇者）。我上周开始了Swift，对语言不太了解。我大部分时间都是谷歌。这是我的代码。提前致谢。为每个按钮添加声音

import UIKit 
import AVFoundation 

class ImagesViewController: UIViewController, AVAudioPlayerDelegate { 

    var audioPlayer: AVAudioPlayer? 

    @IBAction func antman(sender: AnyObject) { 
     audioPlayer!.play() 
    } 
    @IBAction func avengers(sender: AnyObject) { 
     audioPlayer!.play() 
    } 

    func selectSound(alertSound: String, sound: String) { 

     var alertSound: NSURL = NSURL (fileURLWithPath: NSBundle.mainBundle().pathForResource(sound, ofType: "mp3")!) 

     var error: NSError? 
     do { 
      audioPlayer = try AVAudioPlayer(contentsOfURL: alertSound) 
     } 
     catch var error1 as NSError { 
      error = error1 
      audioPlayer = nil 
     } 

     audioPlayer!.delegate = self 
     audioPlayer!.prepareToPlay() 

    } 

    override func viewDidLoad() { 
     super.viewDidLoad() 

     // Do any additional setup after loading the view. 

     selectSound("1", sound: "antman") 
     selectSound("2", sound: "avengers") 
    } 


    override func didReceiveMemoryWarning() { 
     super.didReceiveMemoryWarning() 
     // Dispose of any resources that can be recreated. 
    } 

    func audioPlayerDidFinishPlaying(player: AVAudioPlayer, successfully flag: Bool) { 

    } 

    override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { 
     let newVC: Results = segue.destinationViewController as! Results 
     print("xxx ,%s", segue.identifier) 

     newVC.receivedFirstName = segue.identifier! 
    } 


    /* 
    // MARK: - Navigation 

    // In a storyboard-based application, you will often want to do a little preparation before navigation 
    override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { 
     // Get the new view controller using segue.destinationViewController. 
     // Pass the selected object to the new view controller. 
    } 
    */ 

}

你只需要您的视图控制器上一个'audioPlayer'属性，初始化它两次：一次为“安特曼”和第二次“复仇者“。因此，当您调用'audioPlayer！.play（）'时，它会检索在'audioPlayer'中初始化的最后一个声音并播放它。您可以初始化两个独立的'AVAudioPlayer'属性，或者在按下按钮时用正确的声音初始化'AVAudioPlayer'。对于一个响应按键按压的小声音，这可能表现得足够好。 – Palpatim

你可以这样做：

@IBAction func antman(sender: AnyObject) { 
     selectSound("1", sound: "antman") 
     audioPlayer!.play() 
    } 
    @IBAction func avengers(sender: AnyObject) { 
     selectSound("2", sound: "avengers") 
     audioPlayer!.play() 
    }
