如何在Swift中使用AV Kit播放器视图控制器播放视频？

override func viewDidLoad() {
        super.viewDidLoad()
        let videoURLWithPath = "http://****/5.m3u8"
        let videoURL = NSURL(string: videoURLWithPath)
        playerViewController = AVPlayerViewController()

        dispatch_async(dispatch_get_main_queue()) {
            self.playerViewController?.player = AVPlayer.playerWithURL(videoURL) as AVPlayer
        }
    }

Swift 3.x - 5.x

必要：导入AVKit ，导入AVFoundation

即使您使用AVPlayer

，也需要AVFoundation框架

如果您想使用 AVPlayerViewController ：

let videoURL = URL(string: "https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4")
let player = AVPlayer(url: videoURL!)
let playerViewController = AVPlayerViewController()
playerViewController.player = player
self.present(playerViewController, animated: true) {
    playerViewController.player!.play()
}

或只是 AVPlayer ：

let videoURL = URL(string: "https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4")
let player = AVPlayer(url: videoURL!)
let playerLayer = AVPlayerLayer(player: player)
playerLayer.frame = self.view.bounds
self.view.layer.addSublayer(playerLayer)
player.play()

最好将此代码放入方法中：覆盖func viewDidAppear（_ animated：Bool）或之后的某个地方。

<强>目标C

AVPlayerViewController ：

NSURL *videoURL = [NSURL URLWithString:@"https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4"];
AVPlayer *player = [AVPlayer playerWithURL:videoURL];
AVPlayerViewController *playerViewController = [AVPlayerViewController new];
playerViewController.player = player;
[self presentViewController:playerViewController animated:YES completion:^{
  [playerViewController.player play];
}];

或只是 AVPlayer ：

NSURL *videoURL = [NSURL URLWithString:@"https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4"];
AVPlayer *player = [AVPlayer playerWithURL:videoURL];
AVPlayerLayer *playerLayer = [AVPlayerLayer playerLayerWithPlayer:player];
playerLayer.frame = self.view.bounds;
[self.view.layer addSublayer:playerLayer];
[player play];

试试这个，绝对适用于Swift 2.0 

 let player = AVPlayer(URL: url)
    let playerController = AVPlayerViewController()

    playerController.player = player
    self.addChildViewController(playerController)
    self.view.addSubview(playerController.view)
    playerController.view.frame = self.view.frame

    player.play()

答案 2 :(得分：11)

试试这个

var player:AVPlayer!
var avPlayerLayer:AVPlayerLayer = AVPlayerLayer(player: player)
avPlayerLayer.frame = CGRectMake(your frame)
self.view.layer .addSublayer(avPlayerLayer)
var steamingURL:NSURL = NSURL(string:playerURL)
player = AVPlayer(URL: steamingURL)
player.play()

Swift 3.0完整源代码： 

import UIKit
    import AVKit
    import AVFoundation

    class ViewController: UIViewController,AVPlayerViewControllerDelegate
    {
        var playerController = AVPlayerViewController()


        @IBAction func Play(_ sender: Any)
        {
            let path = Bundle.main.path(forResource: "video", ofType: "mp4")

            let url = NSURL(fileURLWithPath: path!)

            let player = AVPlayer(url:url as URL)

            playerController = AVPlayerViewController()


            NotificationCenter.default.addObserver(self, selector: #selector(ViewController.didfinishplaying(note:)),name:NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: player.currentItem)

            playerController.player = player

            playerController.allowsPictureInPicturePlayback = true

            playerController.delegate = self

            playerController.player?.play()

            self.present(playerController,animated:true,completion:nil)
        }

        func didfinishplaying(note : NSNotification)
        {
            playerController.dismiss(animated: true,completion: nil)
            let alertview = UIAlertController(title:"finished",message:"video finished",preferredStyle: .alert)
            alertview.addAction(UIAlertAction(title:"Ok",style: .default, handler: nil))
            self.present(alertview,animated:true,completion: nil)
        }


        func playerViewController(_ playerViewController: AVPlayerViewController, restoreUserInterfaceForPictureInPictureStopWithCompletionHandler completionHandler: @escaping (Bool) -> Void) {
                let currentviewController =  navigationController?.visibleViewController

                if currentviewController != playerViewController
                {
                    currentviewController?.present(playerViewController,animated: true,completion:nil)
                }


            }
    }

Objective c

This only works in Xcode 7

Go to .h file and import AVKit/AVKit.h and AVFoundation/AVFoundation.h. Then go .m file and add this code:

NSURL *url=[[NSBundle mainBundle]URLForResource:@"arreg" withExtension:@"mp4"];
AVPlayer *video=[AVPlayer playerWithURL:url];
AVPlayerViewController *controller=[[AVPlayerViewController alloc]init];
controller.player=video;
[self.view addSubview:controller.view];
controller.view.frame=self.view.frame;
[self addChildViewController:controller];
[video play];

iOS10 / Swift3 / Xcode 8中的错误（？！）？

if let url = URL(string: "http://devstreaming.apple.com/videos/wwdc/2016/102w0bsn0ge83qfv7za/102/hls_vod_mvp.m3u8"){
    let playerItem = AVPlayerItem(url: url)
    let player = AVPlayer(playerItem: playerItem)
    let playerLayer = AVPlayerLayer(player: player)
    playerLayer.frame=CGRect(x: 10, y: 10, width: 300, height: 300)
    self.view.layer.addSublayer(playerLayer)
}

不起作用（空矩形......）

这有效：

if let url = URL(string: "http://devstreaming.apple.com/videos/wwdc/2016/102w0bsn0ge83qfv7za/102/hls_vod_mvp.m3u8"){

            let player = AVPlayer(url: url)
            let controller=AVPlayerViewController()
            controller.player=player
            controller.view.frame = self.view.frame
            self.view.addSubview(controller.view)
            self.addChildViewController(controller)
            player.play()
        }

使用MPMoviePlayerController： 

 import UIKit
 import MediaPlayer

 class ViewController: UIViewController {

     var streamPlayer : MPMoviePlayerController =  MPMoviePlayerController(contentURL: NSURL(string:"video url here"))
     override func viewDidLoad() {
         super.viewDidLoad()
         streamPlayer.view.frame = self.view.bounds
         self.view.addSubview(streamPlayer.view)

         streamPlayer.fullscreen = true
         // Play the movie!
         streamPlayer.play()
}
}

使用AVPlayer： 

import AVFoundation

var playerItem:AVPlayerItem?
var player:AVPlayer?

override func viewDidLoad() {
        super.viewDidLoad() 
      let url = NSURL(string: "url of the audio or video") 
      playerItem = AVPlayerItem(URL: url!)
      player=AVPlayer(playerItem: playerItem!)
      let playerLayer=AVPlayerLayer(player: player!)
      playerLayer.frame=CGRectMake(0, 0, 300, 50)
      self.view.layer.addSublayer(playerLayer)
}

我有一个播放按钮来处理按钮点击。

playButton.addTarget(self, action: "playButtonTapped:", forControlEvents: .TouchUpInside)

func playButtonTapped(sender: AnyObject) {
        if player?.rate == 0
        {
            player!.play()
            playButton.setImage(UIImage(named: "player_control_pause_50px.png"), forState: UIControlState.Normal)
        } else {
            player!.pause()
            playButton.setImage(UIImage(named: "player_control_play_50px.png"), forState: UIControlState.Normal)
        }
    }

我添加了一个侦听AVPlayerItemDidPlayToEndTimeNotification的观察者。 

override func viewWillAppear(animated: Bool) {
        NSNotificationCenter.defaultCenter().addObserver(self, selector: "finishedPlaying:", name: AVPlayerItemDidPlayToEndTimeNotification, object: playerItem)
    }

override func viewWillDisappear(animated: Bool) {
        NSNotificationCenter.defaultCenter().removeObserver(self)
    }

视频/音频播放完成后，重置按钮图像和通知

  func finishedPlaying(myNotification:NSNotification) {
        playButton.setImage(UIImage(named: "player_control_play_50px.png"), forState: UIControlState.Normal)

        let stopedPlayerItem: AVPlayerItem = myNotification.object as! AVPlayerItem
        stopedPlayerItem.seekToTime(kCMTimeZero)
    }

Swift 5 +

首先，您必须在视图控制器内部全局定义2个变量。

var player: AVPlayer!
var playerViewController: AVPlayerViewController!

在这里，我正在将播放器添加到所需的视图。

@IBOutlet weak var playerView: UIView!

然后将以下代码添加到 viewDidLoad 方法。

let videoURL = URL(string: "videoUrl")
self.player = AVPlayer(url: videoURL!)
self.playerViewController = AVPlayerViewController()
playerViewController.player = self.player
playerViewController.view.frame = self.playerView.frame
playerViewController.player?.pause()
self.playerView.addSubview(playerViewController.view)

如果未全局定义 player 和 playerViewController ，则无法嵌入播放器。

        player = AVPlayer(url: url)
        let playerLayer = AVPlayerLayer(player: player)
        playerLayer.frame = self.viewPlay.bounds
        self.viewPlay.layer.addSublayer(playerLayer)

只需将Sample Videos的示例视频添加到项目中

添加了操作按钮，用于播放以下快速代码示例中的来自网站和本地的视频

import UIKit
import AVKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        //TODO : Make Sure Add and copy "SampleVideo.mp4" file in project before play
    }

    @IBAction func playWebVideo(_ sender: Any) {

        guard let url = URL(string: "https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4") else {
            return
        }
        // Create an AVPlayer, passing it the HTTP Live Streaming URL.
        let player = AVPlayer(url: url)
        let controller = AVPlayerViewController()
        controller.player = player
        present(controller, animated: true) {
            player.play()
        }
    }

    @IBAction func playLocalVideo(_ sender: Any) {

        guard let path = Bundle.main.path(forResource: "SampleVideo", ofType: "mp4") else {
            return
        }
        let videoURL = NSURL(fileURLWithPath: path)

        // Create an AVPlayer, passing it the local video url path
        let player = AVPlayer(url: videoURL as URL)
        let controller = AVPlayerViewController()
        controller.player = player
        present(controller, animated: true) {
            player.play()

快速5 

  @IBAction func buttonPressed(_ sender: Any) {
    let videoURL = course.introductionVideoURL
    let player = AVPlayer(url: videoURL)
    let playerViewController = AVPlayerViewController()
    playerViewController.player = player

    present(playerViewController, animated: true, completion: {

        playerViewController.player!.play()
    })

//这里的课程包括一个模型文件，在其中提供了URL，因此我使用课程函数从模型中调用该函数。

//也IntroductionVideoUrl是我在模型内部声明的URL。 

 var introductionVideoURL: URL

或者，您也可以使用以下代码代替从模型中调用函数

  

替换此代码

  let videoURL = course.introductionVideoURL

使用

  guard let videoURL = URL(string: "https://something.mp4) else {
