AVPlayerViewController in UICollectionViewCell bug

问题:

In my UICollectionView i have a cell. This is my 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!
}

The problem is that the AVPlayerViewController does not appear on each cell. But only on the cell that is under the one at i looking at, so if i scroll down in my UICollectionView and once a new cell appear on the screen, the AVPlayerViewController is on that cell and not the cell in the middel of screen. Any suggestions what might me wrong here?

You need a new aPlayer and moviePlayerController for each cell which has the video in it. Something like this should do it:

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)

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

        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!
    }
