我是Swift和移动的开发的新手。我正在为tvOS编写一个React Native应用程序，我需要在Swift中实现JWPlayerTVKit SDK，因为react-native-jw-media-player不支持tvOS，我已经构建了它的react原生iOS版本。
我已经设法有视频播放，但感觉像处理播放器的过程停止，而视频继续播放.基本上，播放器应该有控制（播放，暂停，时间滚动，等.）这不会出现和事件jwplayerIsReady不被解雇.
我假设与视频播放器交互的线程在配置播放器后添加20秒延迟时死亡。在20秒内播放器控件可见，播放器事件按预期响应。20秒后，视频继续播放，有声音，但控件不可用。
下面是我的代码：
bridging-header.h

#import "React/RCTBridgeModule.h"
#import "React/RCTViewManager.h"

JWPlayerViewManager.m

#import "React/RCTViewManager.h"
@interface RCT_EXTERN_MODULE(JWPlayerViewManager, RCTViewManager)
@end

JWPlayerViewManager.swift

import Foundation
import React

@objc(JWPlayerViewManager)
class JWPlayerViewManager: RCTViewManager {
  override func view() -> UIView! {
      let viewController = JWPlayerViewController()
      let containerView = UIViewController()
      containerView.addChild(viewController)
      containerView.view.addSubview(viewController.view)
      return viewController.view
  }
  
  override static func requiresMainQueueSetup() -> Bool {
    return true
  }
}

JWPlayerViewController.swift

import UIKit
import JWPlayerTVKit

class JWPlayerViewController: JWCinematicViewController {
  override func viewDidLoad() {
    super.viewDidLoad()
    do {
      JWPlayerKitLicense.setLicenseKey("123123123");
    
      // Last, configure the player
      player.configurePlayer(with: try setUpPlayer())

      // I have managed to see the controls and the ready, visible events to fire after I have added this piece of code
      // note: without self.player.play() the controls and the events do not work either
      DispatchQueue.main.asyncAfter(deadline: .now() + 20) {
        self.player.play()
        print("play")
      }
    } catch {
        // Handle builder failure
        print(error)
    }
  }
  
  /**
   Set up the player with a simple configuration.
   */
  private func setUpPlayer() throws -> JWPlayerConfiguration {
          let videoSource1 = try JWVideoSourceBuilder()
            .file(URL(string:"https://cdn.jwplayer.com/videos/123.mp4")!)
            .label("270p")
            .defaultVideo(false)
            .build()
          
          let videoSource2 = try JWVideoSourceBuilder()
            .file(URL(string:"https://cdn.jwplayer.com/videos/456.mp4")!)

          let mediaTrack = try JWCaptionTrackBuilder()
            .file(URL(string:"https://cdn.jwplayer.com/tracks/123.srt")!)
            .label("eng")
            .defaultTrack(true)
            .build()
          
          // First, build a player item with the stream URL
          let item = try JWPlayerItemBuilder()
              .title("My Title")
              .description("My description.")
              .videoSources([videoSource1, videoSource2])
              .mediaTracks([mediaTrack])
              .build()

          // Second, build a player configuration using the player item
          return try JWPlayerConfigurationBuilder()
              .playlist([item])
              .autostart(false)
              .build()
    }
  
  override func controlBarVisibilityChanged(isVisible: Bool) {
    print("control bar")
    print((isVisible) ? "visible" : "not visible")
  }
  
  override func jwplayer(_ player: JWPlayer, isVisible: Bool) {
      print("isVisible")
  }
  
  // Player is ready
  override func jwplayerIsReady(_ player: JWPlayer) {
      super.jwplayerIsReady(player)
    print("player is ready")
  }

App.tsx

import { Dimensions, requireNativeComponent, View } from 'react-native';

const JWPlayerView = requireNativeComponent('JWPlayerView', null);

const App = () => {
  return (
    <View style={{ flex: 1 }}>
      <JWPlayerView
        style={{
          flex: 1,
          backgroundColor: '#ff0000',
          height: Dimensions.get('window').width,
        }}
      />
    </View>
  );
};

export default App;

我是一个有网络开发背景的人，所以我可能误解了一些原则，非常感谢你的帮助！
