在 Storyboard 中实现视频视图

Question

我想构建一个简单的视频应用程序，它可以查看用户添加的视频表单 youtube 链接。 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

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

这是一个 Swift 示例

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通知，它有很多内置的可能性。所以看看吧。

播放视频苹果提供了 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 https://github.com/gilesvangruisen/Swift-YouTube-Player 获得帮助

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 中（代码少一点）：

1. 在界面构建器（故事板）中，添加“AVKit Player View Controller”

2. 创建一个从 AVPlayerViewController 派生的视图控制器：

   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()
     }
   }
   

3. 不要忘记在情节提要的身份检查器中连接这个自定义类 :)

注意：此示例使用指向捆绑资源的视频 URL。
