arrays - Swift:音频文件数组

Question

如何使用 Swift 2 创建要在 Collection View 上使用的音频文件数组？

有 4 个选项“Ocean”、“Birds”、“Nature”、“Waves”，它们显示为单元格。

单击单元格时，我需要它来播放声音。你能帮忙吗？

    var imageArray = [UIImage(named: "ocean"),UIImage(named: "birds"),UIImage(named: "nature"),UIImage(named: "wave")]
var nameArray = ["Ocean","Birds","Nature","Waves"]



func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
    return self.imageArray.count
}

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "cell", for: indexPath) as! homeCollectionViewCell

    cell.iconImage?.image = imageArray[indexPath.item!]
    cell.label.text = nameArray[indexPath.item!]

    return cell
}

你知道怎么播放声音吗？你做到了吗？ 如果是这样，您需要使用以下函数并执行如下操作:

func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) {
        //grab the sound from the array
        let sound = your_array_with_sounds[indexPath.row]

        //if you want to play the sound in this view:
           <code to play the sound>          
        //if you want to play the sound in another view:
           <perform the segue and pass the sound to the view you want>
    }
