如何发布MPMoviePlayerController？

import MediaPlayer
import AVFoundation

let moviePlayer = MPMoviePlayerController(contentURL: URL(string: "https://example.com/path/to/video.mp4"))

moviePlayer.controlStyle = .fullscreen
moviePlayer.shouldAutoplay = true
moviePlayer.setVolume(1.0, animated: false)

view.addSubview(moviePlayer.view)

moviePlayer.view.frame = CGRect(x: 0, y: 0, width: view.bounds.width, height: view.bounds.height)

moviePlayer.prepareToPlay()

NotificationCenter.default.addObserver(self, selector: #selector(moviePlaybackDidFinish(notification:)), name: .MPMoviePlayerPlaybackDidFinish, object: moviePlayer)

@objc func moviePlaybackDidFinish(notification: Notification) {
    // 在此处理视频播放结束事件
}

deinit {
    NotificationCenter.default.removeObserver(self, name: .MPMoviePlayerPlaybackDidFinish, object: moviePlayer)
}
