逐步：使用 Swift 的簡單視頻應用

匯入原生 SDK

雖然 iOS 的布萊特灣本機播放器 SDK 是用 Obj-C 編寫的，我們可以簡單地導入框架模塊到我們的 Swift 項目。

1. 低於現有的import指令，添加以下內容以導入 Brightcove Native Player SDK：

   import BrightcovePlayerSDK

使用您的價值自訂專案

設定您的帳戶 ID 的值，將在稍後的步驟中傳送到 Brightcove。

1. 以下#import指令，為您的 Brightcove 帳戶 ID 添加您自己的值。這將用於向 Brightcove 註冊您的應用程序。

   let kViewControllerAccountID = "your account id" // For Brightcove registration

設置班級代表

這可讓您的應用程式聆聽和回應視訊播放事件和播放器控制事件。

1. 更新視圖控制器類，如下所示：

   class ViewController: UIViewController, BCOVPlaybackControllerDelegate {

聲明常量並設置視圖

1. 在裡面ViewController類，添加以下內容：

   • 第 14 行：初始化共享管理器。這BCOVPlayerSDKManager class 是一個單例，允許您在 SDK 生態系統中創建其他對象。
   • 第 15 行：定義播放控制器的常數。這BCOVPlaybackController有控製播放功能的方法。

   • 第 16 行：定義視圖的變數。

   class ViewController: UIViewController, BCOVPlaybackControllerDelegate {
     let sharedSDKManager = BCOVPlayerSDKManager.shared()
     let playbackController :BCOVPlaybackController
     @IBOutlet weak var videoContainerView: UIView!

創建一個初創函數

1. 在上一步的代碼下方，創建一個init()功能如下：
   • 第 20 行：使用共用管理員來建立播放控制器。

   • 第25行：將您的Video Cloud Publisher ID發送到Brightcove Analytics以註冊您的應用。

   • 第 28-30 行：設置代表並打開自動前進和自動播放功能。

   required init?(coder aDecoder: NSCoder) {
     // Create the Brightcove playback controller
     playbackController = (sharedSDKManager?.createPlaybackController())!
   
     super.init(coder: aDecoder)
   
     // Register your app with Brightcove
     playbackController.analytics.account = kViewControllerAccountID
   
     // Configure the player
     playbackController.delegate = self
     playbackController.isAutoAdvance = true
     playbackController.isAutoPlay = true
   }

設定播放程式

1. 在裡面viewDidLoad()功能，添加以下內容：

   • 38-40行：使用 url 路徑創建一個視頻源數組。
   • 第43-45行：配置播放控制器的視圖。
   • 第 48 行：添加播放器視圖作為主視圖的子視圖。
   • 第 49 行：關自動調整掩碼 .
   • 第50-55行：使用「自動佈局」來定義播放器視圖的動態約束。
   • 第 58 行：將播放器視圖與播放控制器產生關聯。
   • 第61行：將視訊陣列新增至控制器的播放佇列。

   • 第62行：開始播放第一個視訊。

   override func viewDidLoad() {
     super.viewDidLoad()
     // Do any additional setup after loading the view, typically from a nib.
   
     // Create an array of videos
     var videoArray = [AnyObject]()
     videoArray = [videoWithURL(url: NSURL(string: "https://solutions.brightcove.com/bcls/assets/videos/Great_Horned_Owl.mp4")!),
                   videoWithURL(url: NSURL(string: "https://solutions.brightcove.com/bcls/assets/videos/Great_Blue_Heron.mp4")!)]
   
     // Set up the player view with a standard VOD layout.
     guard let playerView = BCOVPUIPlayerView(playbackController: self.playbackController, options: nil, controlsView: BCOVPUIBasicControlView.withVODLayout()) else {
         return
     }
   
     // Install the container view and match its size.
     self.videoContainerView.addSubview(playerView)
     playerView.translatesAutoresizingMaskIntoConstraints = false
     NSLayoutConstraint.activate([
         playerView.topAnchor.constraint(equalTo: self.videoContainerView.topAnchor),
         playerView.rightAnchor.constraint(equalTo: self.videoContainerView.rightAnchor),
         playerView.leftAnchor.constraint(equalTo: self.videoContainerView.leftAnchor),
         playerView.bottomAnchor.constraint(equalTo: self.videoContainerView.bottomAnchor)
     ])
   
     // Associate the playerView with the playback controller.
     playerView.playbackController = playbackController
   
     // Load the video array into the player and start video playback
     playbackController.setVideos(videoArray as NSArray)
     playbackController.play();
   }

設定影片來源的傳送方式

1. 以下viewDidLoad()函數，創建一個函數，為BCOVSources屬於視頻。

   func videoWithURL(url: NSURL) -> BCOVVideo {
       // Set the delivery method for BCOVSources that belong to a video
       let source:BCOVSource = BCOVSource(url: url as URL, deliveryMethod: kBCOVSourceDeliveryHLS, properties: nil)
       let video = BCOVVideo.init(source: source, cuePoints: BCOVCuePointCollection.init(array: []), properties: [NSObject:AnyObject]())
       return video!
   }

            return
        }

        // Install in the container view and match its size.
        self.videoContainerView.addSubview(playerView)
        playerView.translatesAutoresizingMaskIntoConstraints = false
        NSLayoutConstraint.activate([
            playerView.topAnchor.constraint(equalTo: self.videoContainerView.topAnchor),
            playerView.rightAnchor.constraint(equalTo: self.videoContainerView.rightAnchor),
            playerView.leftAnchor.constraint(equalTo: self.videoContainerView.leftAnchor),
            playerView.bottomAnchor.constraint(equalTo: self.videoContainerView.bottomAnchor)
        ])

        // Associate the playerView with the playback controller.
        playerView.playbackController = playbackController

        // Load the video array into the player and start video playback
        playbackController.setVideos(videoArray as NSArray)
        playbackController.play();
    }

    func videoWithURL(url: NSURL) -> BCOVVideo {
      // Set the delivery method for BCOVSources that belong to a video
      let source:BCOVSource = BCOVSource(url: url as URL, deliveryMethod: kBCOVSourceDeliveryHLS, properties: nil)
      let video = BCOVVideo.init(source: source, cuePoints: BCOVCuePointCollection.init(array: []), properties: [NSObject:AnyObject]())
      return video!
    }
}

該應用程序已準備好在 iPhone，iPad 或 iOS 模擬器上構建和運行。您應該能夠播放數組中定義的視頻。
