cell复用时视频封面图显示错乱

[BackWorld]

解决：

var moviePath : String?{
        didSet{
            if let iPath = moviePath {
                moviePlayer.contentURL = NSURL(fileURLWithPath: iPath, isDirectory: false)
                moviePlayer.prepareToPlay()
                // 移除上次复用的cell的image，防止显示错乱
                imageView.removeFromSuperview()
                // 再重新add上更换完图片的当前cell对应的image
                moviePlayer.view.addSubview(imageView)
            }
        }
    }

func playerDisplayChange()
    {
        // 准备播放时[预览图加载出来时] 移除封面image
        if moviePlayer.readyForDisplay {
            imageView.removeFromSuperview()
        }
    }
