UICollectionViewCell 错误中的 AVPlayerViewController？

Question

在我的 UICollectionView 中有一个单元格。这是我的 cellForItemAtIndexPath

func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell
{
    var videoCell = collectionView.dequeueReusableCellWithReuseIdentifier("cellVideo", forIndexPath: indexPath) as? CollectionViewCell

    let post = self.arrayOfDetails[indexPath.row]

    var myUrl = post.image // post.image is image url

    let fileUrl = NSURL(string: post.image)

    aPlayer = AVPlayer(URL: fileUrl)

    moviePlayerController.player = aPlayer
    moviePlayerController.view.frame = CGRectMake(8, 8, videoCell!.frame.size.width-16, 310)
    moviePlayerController.videoGravity = AVLayerVideoGravityResizeAspectFill
    moviePlayerController.view.sizeToFit()
    moviePlayerController.showsPlaybackControls = true
    videoCell!.addSubview(moviePlayerController.view)

    return videoCell!
}

问题是 AVPlayerViewController 没有出现在每个单元格上。但仅在我正在查看的单元格下方，因此，如果我在 UICollectionView 中向下滚动，并且一旦屏幕上出现一个新单元格，AVPlayerViewController 就位于该单元格上，而不是屏幕中间的单元格。有什么建议我在这里可能错了吗？

对于其中包含视频的每个单元格，您需要一个新的 aPlayer 和 moviePlayerController。应该这样做：

func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell
    {
        var videoCell = collectionView.dequeueReusableCellWithReuseIdentifier("cellVideo", forIndexPath: indexPath) as? CollectionViewCell

        var aPlayer = AVPlayer()
        let moviePlayerController = AVPlayerViewController()

        let post = self.arrayOfDetails[indexPath.row]

        var myUrl = post.image // post.image is image url

        let fileUrl = NSURL(string: post.image)

        aPlayer = AVPlayer(URL: fileUrl)

        moviePlayerController.player = aPlayer
        moviePlayerController.view.frame = CGRectMake(8, 8, videoCell!.frame.size.width-16, 310)
        moviePlayerController.videoGravity = AVLayerVideoGravityResizeAspectFill
        moviePlayerController.view.sizeToFit()
        moviePlayerController.showsPlaybackControls = true
        videoCell!.addSubview(moviePlayerController.view)

        return videoCell!
    }
