如何在CarPlay上播放视频？

Question

我有到视频的网页链接，在iOS中，我可以在AVPlayerViewController/AVPlayer中使用AVFoundation/AVKit框架打开它。

但是我如何在CarPlay中打开它呢？

CarPlay文档的文本：

不能使用媒体播放器框架直接播放视频媒体项目。若要播放包含MPMediaItem对象的视频，请使用来自AVFoundation的AVPlayer对象。系统播放器还提供了一种使用系统应用程序播放视频项目的方法。

extension AppDelegate: CPListTemplateDelegate {
    func listTemplate(_ listTemplate: CPListTemplate, didSelect item: CPListItem, completionHandler: @escaping () -> Void) {
        if let url = item.userInfo as? String {
            self.playVideo(url)
        }
    }
}

我将分享在carplay上播放一个示例视频所遵循的步骤

在Appdelgate.h中添加以下头文件

import CarPlay
import AVKit

然后添加CPApplicationDelegate

添加这些令人愉快的方法

 // MARK: - CPApplicationDelegate methods
func application(_ application: UIApplication, didConnectCarInterfaceController interfaceController: CPInterfaceController, to window: CPWindow) {
    print("[CARPLAY] CONNECTED TO CARPLAY!")

    // Keep references to the CPInterfaceController (handles your templates) and the CPMapContentWindow (to draw/load your own ViewController's with a navigation map onto)
    self.interfaceController = interfaceController
    self.carWindow = window
    guard let path = Bundle.main.path(forResource: "video", ofType: "mp4") else
                        {
                            return
                        }
                        let videoURL = NSURL(fileURLWithPath: path)
                        let player = AVPlayer(url: videoURL as URL)
                        let playerController = AVPlayerViewController()
                        playerController.player = player
                        player.play()

            window.rootViewController = playerController
}

func application(_ application: UIApplication, didDisconnectCarInterfaceController interfaceController: CPInterfaceController, from window: CPWindow) {
    print("[CARPLAY] DISCONNECTED FROM CARPLAY!")
}
