Question

我有一个包含全宽UIImageView的单元格，我正在创建一个AVPlayerLayer来播放内嵌视频。这几乎是完美的，唯一的问题是当它被添加到previewImage图像视图时，它是一个完美显示的全宽图像视图，它在左侧和右侧有一个1像素的间隙。因此，当视频播放时，您可以真正注意到它并且它非常刺耳。

我这样设置：

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    tableView.deselectRow(at: indexPath, animated: false)

    let cell = tableView.cellForRow(at: indexPath) as! GameMediaCell

    if (cell.playerLayer != nil) {
        cell.playerLayer?.player?.pause()
        cell.playerLayer?.removeFromSuperlayer()
        cell.playerLayer = nil

    } else {
        if let clipURI = viewModel?.mediaURIForIndex(indexPath.row) {

            let player = AVPlayer(url: clipURI)
            let playerLayer = AVPlayerLayer(player: player)

            playerLayer.frame = cell.previewImage.frame

            cell.previewImage.layer.addSublayer(playerLayer)
            cell.playerLayer = playerLayer

            playerLayer.player?.play()
        }
    }
}

Answer 1

在将播放器图层添加为子视图之前添加此行。

self.playerLayer.videoGravity = AVLayerVideoGravityResizeAspectFill

Answer 2

这对我有用：

//MARK: Add a new variable to your class where you are using AVPLayer  
let screenRect = UIScreen.mainScreen().bounds

//MARK:Than just create a new frame of AVPLayerLayer
self.avPlayerLayer!.frame = CGRectMake(0, 0, self.screenRect.size.width, self.screenRect.size.height)

将AVPlayerLayer添加为子图层不会完全填充父视图
