Swift 3，XCode 8 - 更改按鈕按下本地視頻 - AVPlayer

我正在嘗試創建一個應用程序，它將更改每個按鈕按下的視頻。Swift 3，XCode 8 - 更改按鈕按下本地視頻 - AVPlayer

目前：視頻循環和按鈕不執行任何操作

目標：按鈕，將循環基於數組的索引下一個視頻。我計劃將另一個陣列與文字說明關聯起來，以便與每個視頻一起播放。

想法：我認爲基於JSON的實現可能會更好。這是我的第一個iOS應用程序，我試圖保持簡單。非常感謝您的意見和幫助！

以下是循環播放視頻的功能。視頻的名稱的名稱已在陣列中叫VideoID的召開方式：

class WorkoutViewController: UIViewController{ 
@IBOutlet weak var videoView: UIView! 
@IBOutlet weak var infoCardView: UIView! 

var currentVidIndex: Int = 0  

var player: AVPlayer? 
var playerLayer: AVPlayerLayer?  

override func viewDidLoad() { 
    super.viewDidLoad() 
    shadowBackground() 
} 
var videoId: [String] = ["bodyweight_fitness_arch","bodyweight_fitness_assisted_squat","bodyweight_fitness_band_dislocates"] 


func setLoopingVideo(){ 
    let path = Bundle.main.path(forResource: videoId[currentVidIndex], ofType: "mp4") 
    let url = URL.init(fileURLWithPath: path!) 
    let player = AVPlayer(url: url) 
    let playerLayer = AVPlayerLayer(player: player) 
    playerLayer.frame = videoView.bounds 
    self.videoView.layer.insertSublayer(playerLayer, at: 0) 
    player.play() 

    // Create observer to monitor when video ends, when it does so set the video time to the start (zero) 

    NotificationCenter.default.addObserver(forName: NSNotification.Name.AVPlayerItemDidPlayToEndTime,object: player.currentItem, queue: nil) 

    { 
     Notification in player.seek(to: kCMTimeZero) 
     player.play() 
    } 

func shadowBackground(){ 
    infoCardView.layer.cornerRadius = 3.0 
    infoCardView.layer.shadowColor = 
      UIColor.black.withAlphaComponent(0.6).cgColor 
    infoCardView.layer.shadowOffset = CGSize(width: 0, height: 0) 
    infoCardView.layer.shadowOpacity = 0.9   

    videoView.layer.cornerRadius = 3.0 
    videoView.layer.shadowColor = 
    UIColor.black.withAlphaComponent(0.6).cgColor 
    videoView.layer.shadowOffset = CGSize(width: 0, height: 0) 
    videoView.layer.shadowOpacity = 0.9 

} 
override func viewDidAppear(_ animated: Bool) { 
    setLoopingVideo() 
} 

@IBAction func showNextVideo(_ sender: UIButton) { 
    if currentVidIndex < videoId.count{ 
     currentVidIndex += 1 
     print (currentVidIndex) 
    } else { 
     NSLog("Nothing") 
    } 
}

如果你想改變每個按鈕點擊一個視頻，你必須總是創造新的AVPlayer對象。

創建並記住您AVPlayer對象
創建並記住您AVPlayerLayer

- 當按鈕點擊 -

從除去AVPlayerLayer父

停止AVPlayer（舊視頻）

轉到步驟1，新視頻URL

謝謝！我懷疑我不得不把它當作一個物體來對待，我只是希望我不必：P – Lancaster

如果有人感興趣： 'func removeVid（）{ if let player = self.player { player。暫停（） self.player =零 } 如果讓層= self.playerLayer { layer.removeFromSuperlayer（） self.playerLayer =零 } self.videoView.layer.sublayers？.removeAll（） }' – Lancaster

這裏是我的解決辦法：

func clearVid(){ 
    if let player = self.player{ 
     player.pause() 
     self.player = nil 

    } 
    if let layer = self.playerLayer{ 
     layer.removeFromSuperlayer() 
     self.playerLayer = nil 
    } 

    self.videoView.layer.sublayers?.removeAll() 
}
