我创建了一个名为UserProfileController的UICollectionView。 我创建了一个名为UserProfilePhotoCell的UICollectionViewCell。 我在UserProfilePhotoCell中创建了avplayer。 当您单击Avplayer时，视频开始播放。
当我单击单元格上的第一个AVPlayer时， 第一，第五，第九单元播放AVplayer。
我该如何解决？

只需使用此代码在具有期望索引的单元中播放视频。
class UserProfilePhotoCell: UICollectionViewCell {
@IBOutlet var viewForVideo: UIView!
@IBOutlet var btnPlayVideo: UIButton!
var blockVideoPlay : ((_ sender : UIButton)->())?
override func awakeFromNib() {
super.awakeFromNib()
removeSubLayerFromVideo()
self.setupMoviePlayer()
}
@IBAction func btnPlayVideoCLK(_ sender: UIButton) {
if blockVideoPlay != nil {
blockVideoPlay!(sender)
}
}
func removeSubLayerFromVideo() {
if let layerArray = viewForVideo.layer.sublayers, layerArray.isEmpty {
for layer in layerArray {
if layer.name == "\(viewForVideo.tag)" {
layer.removeFromSuperlayer()
}
}
}
}
func setupMoviePlayer(){
self.avPlayer = AVPlayer.init(playerItem: self.videoPlayerItem)
avPlayerLayer = AVPlayerLayer(player: avPlayer)
avPlayerLayer?.videoGravity = AVLayerVideoGravity.resizeAspect
avPlayerLayer?.name = "\(viewForVideo.tag)"
avPlayer?.volume = 3
avPlayer?.actionAtItemEnd = .none
avPlayerLayer?.frame = CGRect(x: 0, y: 0, width: UIScreen.width, height: UIScreen.height)
self.viewForVideo.backgroundColor = .clear
self.viewForVideo.layer.insertSublayer(avPlayerLayer!, at: 0)
// This notification is fired when the video ends, you can handle it in the method.
NotificationCenter.default.addObserver(self,
selector: #selector(self.playerItemDidReachEnd(notification:)),
name: NSNotification.Name.AVPlayerItemDidPlayToEndTime,
object: avPlayer?.currentItem)
}
func stopPlayback(){
if let player = self.avPlayer {
if player.isPlaying {
player.pause()
}
}
}
func startPlayback(){
self.avPlayer?.play()
}
// A notification is fired and seeker is sent to the beginning to loop the video again
@objc func playerItemDidReachEnd(notification: Notification) {
//let p: AVPlayerItem = notification.object as! AVPlayerItem
//p.seek(to: kCMTimeZero)
btnPlayVideo.isSelected = false
self.avPlayer?.currentItem?.seek(to: kCMTimeZero, completionHandler: { (success) in
if success {
self.avPlayer?.pause()
}
})
}
}
对于使用此代码的View Controller，您还可以通过var发布单元格中的所有数据，并可以从该单元格中设置URL路径，使其工作正常，确保在视图将消失时您必须停止播放器
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
}
}
}
}
也可以将此扩展名用于检查播放器当前是否正在播放
extension AVPlayer {
var isPlaying: Bool {
return rate != 0 && error == nil
}
}
