Swift 2：为数组中的不同图像播放声音

Question

我得到了一组图像

var cardImages = ["bellota", "manzana", "botas"]

我创建了 myAudioPlayer 来播放声音

let filePath = NSBundle.mainBundle().pathForResource("correct", ofType: "wav")

    if let filePath = filePath
    {

        let filePathURL = NSURL(fileURLWithPath: filePath)

        do {

            try myAudioPlayer = AVAudioPlayer(contentsOfURL: filePathURL)


        } catch {

            print("error")

        }

    }

更改图像的下一个按钮

  @IBAction func nextButtonTapped(sender: UIButton) {

    if imageIndex < 0 {

        imageIndex = maxImages
    }


    cardImageView.image = UIImage(named: cardImages[imageIndex])

    imageIndex++

    if imageIndex > maxImages {

        imageIndex = 0
    }

    cardImageView.image = UIImage(named: cardImages[imageIndex])
}

播放声音按钮：我试图用这种方法做的是在图像改变时播放声音。阵列中的每个图像都有不同的声音。我怎样才能做到这一点？例如 "apple" 将播放声音 1，"orange" 将在按下下一个图像时播放声音 2

 @IBAction func playButtonTapped(sender: UIButton) {


    myAudioPlayer.play()


}

将您的音频加载隔离到函数中：

func setTrack(audioName: String){


    let filePath = NSBundle.mainBundle().pathForResource(audioName, ofType: "wav")

    if let filePath = filePath
    {

        let filePathURL = NSURL(fileURLWithPath: filePath)

        do {

            try myAudioPlayer = AVAudioPlayer(contentsOfURL: filePathURL)


        } catch {

            print("error")

        }

    }
}

然后，在 nextButtonPressed:

@IBAction func nextButtonTapped(sender: UIButton) {

    if imageIndex < 0 {

        imageIndex = maxImages
    }


    cardImageView.image = UIImage(named: cardImages[imageIndex])

    imageIndex++

    if imageIndex > maxImages {

        imageIndex = 0
    }

    cardImageView.image = UIImage(named: cardImages[imageIndex])
    self.setTrack(audioList[imageIndex]) // or any other index you need/you have
}
