我正在製作應用程序以從用戶那裏獲取名稱,然後選擇一個縮略圖(它會播放聲音)。問題是我不能讓它爲每個按鈕播放不同的聲音。它所扮演的是最後一個我把價值鎖定的人(在這種情況下,復仇者)。我上週開始了Swift,對語言不太瞭解。我大部分時間都是谷歌。這是我的代碼。提前致謝。爲每個按鈕添加聲音

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. 
    } 
    */

你只需要您的視圖控制器上一個'audioPlayer'屬性,初始化它兩次:一次爲「安特曼」和第二次「復仇者「。因此,當您調用'audioPlayer!.play()'時,它會檢索在'audioPlayer'中初始化的最後一個聲音並播放它。您可以初始化兩個獨立的'AVAudioPlayer'屬性,或者在按下按鈕時用正確的聲音初始化'AVAudioPlayer'。對於一個響應按鍵按壓的小聲音,這可能表現得足夠好。 – Palpatim

你可以這樣做:

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