Swift实现播放远程视频

• 使用AVPlayer 播放远程视频

• ViewController.swift

import UIKit
import AVFoundation

class ViewController: UIViewController {

    // 成员变量
    var player : AVPlayer?

    // MARK: 懒加载
    private lazy var layer : AVPlayerLayer = {
        // 获取远程视频资源
        // 0.获取远程视频url
        let remoteURL = NSURL(string: "http://v1.mukewang.com/57de8272-38a2-4cae-b734-ac55ab528aa8/L.mp4")
        // 1.根据url资源创建一个播放器
        self.player = AVPlayer(URL: remoteURL!)
        let layer = AVPlayerLayer(player: self.player)
        return layer
    }()

    override func viewDidLoad() {
        super.viewDidLoad()
        view.layer .addSublayer(self.layer)
    }

    override func touchesBegan(touches: Set, withEvent event: UIEvent?) {
        player?.play()
    }

    // 不加下面的方法,虽然可以放视频,可以听到声音
    // 但是不能看到画面,得添加到相应的图层上去
    override func viewDidLayoutSubviews() {
        super.viewDidLayoutSubviews()
        layer.frame = view.bounds
    }

}

• 使用MPMoviePlayerController播放视频

• ViewController.swift

import UIKit
import MediaPlayer

class ViewController: UIViewController {

    /** 播放器*/
    var pc : MPMoviePlayerController?

    override func viewDidLoad() {
        super.viewDidLoad()

        // 0.获取资源路径
        let remoteURL = NSURL(string: "http://v1.mukewang.com/57de8272-38a2-4cae-b734-ac55ab528aa8/L.mp4")
        // 1.创建播放器对象
        pc = MPMoviePlayerController(contentURL: remoteURL)
        view .addSubview((pc?.view)!)
    }

    override func touchesBegan(touches: Set, withEvent event: UIEvent?) {
        pc?.play()
    }

    override func viewDidLayoutSubviews() {
        super.viewDidLayoutSubviews()
        pc?.view.frame = view.bounds
    }
}

• 使用MPMoviePlayerViewController播放视频

• ViewController.swift

import UIKit
import MediaPlayer

class ViewController: UIViewController {

    /** 播放器 */
    var pvc : MPMoviePlayerViewController?

    override func viewDidLoad() {
        super.viewDidLoad()
        // 0.获取远程视频url
        let remoteURL = NSURL(string: "http://v1.mukewang.com/57de8272-38a2-4cae-b734-ac55ab528aa8/L.mp4")
        pvc = MPMoviePlayerViewController(contentURL: remoteURL)

    }

    override func touchesBegan(touches: Set, withEvent event: UIEvent?) {

        if (presentedViewController != nil) {
            return ;
        }
        presentViewController(pvc!, animated: true) { () -> Void in
            self.pvc?.moviePlayer.play()
        }
    }

}

• iOS9.0之后, 需要使用AVPlayerViewController

• ViewController.swift

import UIKit
import AVKit
import AVFoundation

class ViewController: UIViewController {

    /** 播放器 */
    var playerVC: AVPlayerViewController?


    override func viewDidLoad() {
        super.viewDidLoad()

        playerVC = AVPlayerViewController()
        // 0.获取远程视频url
        let remoteURL = NSURL(string: "http://v1.mukewang.com/57de8272-38a2-4cae-b734-ac55ab528aa8/L.mp4")
        let player = AVPlayer(URL: remoteURL!)
        playerVC?.player = player
    }

    override func touchesBegan(touches: Set, withEvent event: UIEvent?) {

        if (presentedViewController != nil) {
            return ;
        }

        presentViewController(playerVC!, animated: true) { () -> Void in
            self.playerVC?.player?.play()
        }
    }

}
