电容自定义 AVPlayer 视图控制器

Question

我是 Swift / iOS 的新手，所以如果我觉得我很愚蠢，我深表歉意。我正在尝试在启动时为我的电容器 iOS 应用程序播放自定义视频闪屏，但我似乎在使用 segues 切换视图控制器时遇到了麻烦。在我的 Main storyboard 上，我有两个 View Controller，一个 Capacitor Bridge View（它可以很好地运行我的 react 应用程序），还有一个 AVPlayer View Controller。

我已将我的 AVPlayer 设置为初始视图控制器，并创建了一个到电容器桥视图的 segue，该 segue 的 id 为“test”，我在视频末尾的自定义 AVPlayer 控制器中调用了 performegue() 方法，尽管它正在运行，但它什么也没做。

这是我的 AVPlayer 的自定义类

//

//  App

import Foundation
import UIKit
import AVFoundation
import AVKit
import Capacitor


class viewControl: AVPlayerViewController {
    
    override func viewDidAppear(_ animated: Bool) {
            playVideo()
        }
        
        let playerController = AVPlayerViewController()
        private func playVideo() {
            guard let path = Bundle.main.path(forResource: "Splash_Screen_Christmas", ofType:"mp4") else {
                debugPrint("splash.m4v not found")
                return
            }
            let player = AVPlayer(url: URL(fileURLWithPath: path))
            playerController.showsPlaybackControls = false
            playerController.player = player
            playerController.videoGravity = .resizeAspectFill
            NotificationCenter.default.addObserver(self, selector: #selector(playerDidFinishPlaying), name: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: playerController.player?.currentItem)
            present(playerController, animated: true) {
                player.play()
            }
        }
        @objc func playerDidFinishPlaying(note: NSNotification) {
           // let storyboard = UIStoryboard(name: "Main", bundle: nil)
            // let vc = storyboard.instantiateViewController(withIdentifier: "MainVC")
            performSegue(withIdentifier: "test", sender: self)
            print("Method, video is finished ")
        }
    
    
}

视频播放后，模拟器记录“视频完成”，但桥视图控制器没有被推送。

我通过避免使用单独的视图控制器解决了这个问题，对于任何使用 Capacitor 添加新视图控制器的人，您需要通过创建 CAPBridgeViewController 的子类来切换视图控制器

import UIKit
import Capacitor
import AVKit
// Instantiate a subclass of CAPBridgeViewController

class capController: CAPBridgeViewController {
    // Define video URL here
    let player: AVPlayer = AVPlayer(url: URL(fileURLWithPath: Bundle.main.path(forResource: "Splash_Screen_Normal", ofType:"mp4")!))
    
      var playerLayer: AVPlayerLayer!

      override func viewWillAppear(_ animated: Bool) {
          super.viewWillAppear(animated)

          playerLayer = AVPlayerLayer(player: player)
          playerLayer.videoGravity = .resizeAspectFill
          playerLayer.frame = self.view.bounds
          view.layer.addSublayer(playerLayer)
          // Try catch to avoid breaking user background audio.
          do {
              try AVAudioSession.sharedInstance().setCategory(AVAudioSession.Category.playback, mode: AVAudioSession.Mode.default, options: .mixWithOthers)
                  try AVAudioSession.sharedInstance().setActive(true)
             } catch {
                  print(error)
             }
          // End of background audio code validation
          player.play()
          NotificationCenter.default.addObserver(self, selector: #selector(playerDidFinishPlaying), name: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: player.currentItem)
      }

      @objc func playerDidFinishPlaying(note: NSNotification) {
          print("Video has finished running.")
          playerLayer.removeFromSuperlayer()
      }
    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
    }
    

    /*
    // MARK: - Navigation

    // In a storyboard-based application, you will often want to do a little preparation before navigation
    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        // Get the new view controller using segue.destination.
        // Pass the selected object to the new view controller.
    }
    */

}
