same video in every five cells

Question

I created a UICollectionView named UserProfileController. I created a UICollectionViewCell named UserProfilePhotoCell. I created avplayer in UserProfilePhotoCell. When you click on Avplayer the video starts.

When I click on the 1st AVPlayer on the cell, The first, fifth, ninth cells play AVplayer.

How can I fix?

Answer 1

Just use this code for play video in the cell with expect index. It will help you a lot and for other also ,

class UserProfilePhotoCell: UICollectionViewCell {

@IBOutlet var viewForVideo: UIView!
@IBOutlet var btnPlayVideo: UIButton!
var blockVideoPlay : ((_ sender : UIButton)->())?

For View Controller use this code also you can post via var all data in the cell and from the cell, you can set URL path it works fine make sure when view Will Disappear you have to stop the player

    class UserProfileController: UICollectionViewController, UICollectionViewDelegateFlowLayout {

   override func viewWillDisappear(_ animated: Bool) {
        super.viewWillDisappear(true)
        for cell in mediaListCollection.visibleCells {
            if let cell = cell as? UserProfilePhotoCell {
                cell.stopPlayback()
            }
        }
    }



    func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {

    var cell = collectionView.dequeueReusableCell(withReuseIdentifier: "cellId", for: indexPath) as! UserProfilePhotoCell

    let url = URL(fileURLWithPath: path, isDirectory: true)
                        cell.videoPlayerItem = AVPlayerItem(url: url)
    cell.viewForVideo.tag = indexPath.row+1
    cell.blockVideoPlay = { (sender) -> Void in
    sender.isSelected = !sender.isSelected
                       if sender.isSelected {
                                cell.startPlayback()
                            }
                            else {
                                cell.stopPlayback()
                            }
    }

    }


    func collectionView(_ collectionView: UICollectionView, didEndDisplaying cell: UICollectionViewCell, forItemAt indexPath: IndexPath) {
            if let cell = cell as? UserProfilePhotoCell {
                cell.stopPlayback()
                        if cell.btnPlayVideo.isSelected {
                            cell.btnPlayVideo.isSelected = false
                        }
            }
        }
    }

Also use this extension for check player is currently playing or not

extension AVPlayer {
    var isPlaying: Bool {
        return rate != 0 && error == nil
    }
}
