我有一个tableview，当它的单元格被点击时，它会在它下面添加一个新单元并播放一个视频，然后它会在整个屏幕中添加一个空白UIView，但它最初是隐藏的。当点击该单元格时，UIView不会隐藏，并且视频成功播放，当点击UIView时，它将转到AVPlayer.Pause()并删除正在播放视频的单元格。单元格已删除，但音频仍在播放。我添加了一个断点，Pause()已经运行。但它根本不起作用。
这是代码：
class Detail_ViewController: UIViewController,UITableViewDataSource,UITableViewDelegate {
var myPlan: PlansInfo!
var planItems: [[[String]]] = []
var videoIndexPath: IndexPath? = nil
var avPlayer: AVPlayer?
@IBOutlet weak var tableView: UITableView!
@IBOutlet weak var view_MengBan: UIView!
@IBOutlet weak var label_PlanName: UILabel!
@IBOutlet weak var label_PlanIntroduce: UILabel!
@IBOutlet weak var imageView_Detail: UIImageView!
@IBOutlet weak var label_PlanTime: UILabel!
func PauseVideo(avPlayer: AVPlayer) {
avPlayer.pause()
}
@IBAction func TapToDeleteVideoGesture(_ sender: UITapGestureRecognizer) {
if videoIndexPath != nil {
avPlayer?.pause()
planItems[0][(videoIndexPath?.section)!].remove(at: (videoIndexPath?.row)!)
planItems[1][(videoIndexPath?.section)!].remove(at: (videoIndexPath?.row)!)
tableView.deleteRows(at: [videoIndexPath!], with: .automatic)
videoIndexPath = nil //让视频选项为空，使得视频能再次被打开
view_MengBan.isHidden = true //让蒙板层隐藏，使手势关闭
print("Video Removed")
}
}
override func viewDidLoad() {
super.viewDidLoad()
view_MengBan.isHidden = true
let amp = AutoMakePlan(key_Kind: myPlan.key_Kind, key_Level: myPlan.key_Level, key_Days: myPlan.key_Days, key_Time: myPlan.key_Time, key_CanJuggle: myPlan.key_CanJuggle)
label_PlanName.text = myPlan.planName
label_PlanTime.text = String(myPlan.actualPlanTime) + " min"
label_PlanIntroduce.text = amp.TranslateKey(key: myPlan.planKey!)?.planIntroduce
imageView_Detail.image = UIImage(named: "Cristiano Ronaldo")
planItems = amp.GetPlanItems(key: myPlan.planKey!, planTime: myPlan.planTime)!
