在Swift中从服务器播放视频文件

Question

我正在尝试使用Swift从服务器播放视频.

我已经导入了MediaPlayer框架,这是我的代码:

import UIKit
import MediaPlayer

class VideoViewController: UIViewController {

   override func viewDidLoad() {
        super.viewDidLoad()

        var url:NSURL = NSURL(string: "http://jplayer.org/video/m4v/Big_Buck_Bunny_Trailer.m4v")        
        var moviePlayer = MPMoviePlayerController(contentURL: url)

        moviePlayer.view.frame = CGRect(x: 20, y: 100, width: 200, height: 150)        
        self.view.addSubview(moviePlayer.view)

        moviePlayer.fullscreen = true        
        moviePlayer.controlStyle = MPMovieControlStyle.Embedded        
   }
}

当我在模拟器中运行时,我只得到一个黑盒子,但无论我在哪里尝试加载视频,都没有播放视频.

UPDATE

这是当前的代码

var url:NSURL = NSURL(string: "http://jplayer.org/video/m4v/Big_Buck_Bunny_Trailer.m4v")

var moviePlayer = MPMoviePlayerController(contentURL: url)

moviePlayer.view.frame = CGRect(x: 20, y: 100, width: 200, height: 150)        
moviePlayer.movieSourceType = MPMovieSourceType.File

self.view.addSubview(moviePlayer.view)        
moviePlayer.prepareToPlay()
moviePlayer.play()

这个代码有趣地播放~2秒的视频再次变黑!

解决了:

import UIKit
import AVKit
import AVFoundation

class ViewController: UIViewController {

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

        let url = URL(string: "https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4")!

        playVideo(url: url)
    }

    func playVideo(url: URL) {
        let player = AVPlayer(url: url)

        let vc = AVPlayerViewController()
        vc.player = player

        self.present(vc, animated: true) { vc.player?.play() }
    }
}

    }

导入库:

import AVKit
import AVFoundation
import MediaPlayer
import AudioToolbox   

像这样设置delegaete

AVPlayerViewControllerDelegate

Wrtie漂亮的代码,你想像按钮动作一样玩:

let videoURL = URL(string: "https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4")
    let player = AVPlayer(url: videoURL!)
    let playervc = AVPlayerViewController()
    playervc.delegate = self
    playervc.player = player
    self.present(playervc, animated: true) {
        playervc.player!.play()
    }
