在 Storyboard 中实现视频视图

Question

我想构建简单的视频应用程序，它可以观看用户添加的 YouTube 链接形式的视频。我没有找到 "VideoView" 我的意思是如果图像视图用于图像，那么 UIView 用于视频。

Answer 1

原库中没有执行视频查看功能的对象。但是您可以在您的项目中导入 MediaPlayer 框架并以编程方式添加它。

这里有一个 Swift 例子

import MediaPlayer

class Step1ViewController: UIViewController {

var moviePlayer: MPMoviePlayerController?

override func viewDidLoad() {
    super.viewDidLoad()

    playVideo()
}

func playVideo() {

    let videoView = UIView(frame: CGRectMake(self.view.bounds.origin.x, self.view.bounds.origin.y, self.view.bounds.width, self.view.bounds.height))

    let pathToEx1 = NSBundle.mainBundle().pathForResource("myVideoFile", ofType: "mp4")
    let pathURL = NSURL.fileURLWithPath(pathToEx1!)
    moviePlayer = MPMoviePlayerController(contentURL: pathURL)
    if let player = moviePlayer {
        player.view.frame = videoView.bounds
        player.prepareToPlay()
        player.scalingMode = .AspectFill
        videoView.addSubview(player.view)
    }

    self.view.addSubview(videoView)
}

}

至于进一步的定制和应用程序通知，它有很多内置的可能性。所以检查一下。

为了播放视频苹果已经提供了MPMovieViewController 看到这个 https://developer.apple.com/library/prerelease/ios/documentation/MediaPlayer/Reference/MPMoviePlayerController_Class/index.html

在 youtube 视频案例中，我们使用了嵌入式链接，因此您将从中获得帮助 https://github.com/gilesvangruisen/Swift-YouTube-Player

Answer 3

import AVFoundation
import AVKit

class ViewController: UIViewController { 
    var player = AVPlayer()
    var playerController = AVPlayerViewController()

    func playVideo() {     
        let videoURL = NSURL(string: videoUrl)
        player = AVPlayer(url: videoURL! as URL)
        let playerController = AVPlayerViewController()
        playerController.player = player
        self.addChildViewController(playerController)

    // Add your view Frame
         playerController.view.frame = self.view.frame

   // Add subview in your view
         self.view.addSubview(playerController.view)

   player.play()
 }

 func stopVideo() {
    player.pause()
 }
}

Answer 4

在Xcode 10（代码少一点）：

在界面生成器（故事板）中，添加“AVKit Player View Controller”

创建一个派生自 AVPlayerViewController:

的视图控制器

import UIKit
import AVKit

class VideoPlayerViewController: AVPlayerViewController {

  override func viewDidLoad() {
    super.viewDidLoad()

    let videoURL = Bundle.main.url(forResource: "video", withExtension: "mp4")!
    self.player = AVPlayer(url: videoURL)
  }

  override func viewDidAppear(_ animated: Bool) {
    self.player?.play()
  }
}

不要忘记在故事板的身份检查器中连接此自定义 class :)

Note: this example uses video URL pointing to a bundle's resource.
