Play Video

self.player.replaceVideo(url)

Custom player view

• Subclass VGPlayerView
• Alloc VGPlaye when set up

let playeView = VGCustomPlayerView()
self.player = VGPlayer(playerView: playeView)

// customPlayerView
class VGCustomPlayerView: VGPlayerView {
    var playRate: Float = 1.0
    var rateButton = UIButton(type: .custom)

    override func configurationUI() {
        super.configurationUI()
        self.topView.backgroundColor = #colorLiteral(red: 0, green: 0, blue: 0, alpha: 0.09701412671)
        self.bottomView.backgroundColor = #colorLiteral(red: 0, green: 0, blue: 0, alpha: 0.09701412671)
        self.topView.addSubview(rateButton)
        rateButton.snp.makeConstraints { (make) in
            make.left.equalTo(titleLabel.snp.right).offset(10)
            make.centerY.equalTo(closeButton)
        }
        rateButton.tintColor = #colorLiteral(red: 1, green: 1, blue: 1, alpha: 1)
        rateButton.setTitle("x1.0", for: .normal)
        rateButton.titleLabel?.font   = UIFont.boldSystemFont(ofSize: 12.0)
        rateButton.addTarget(self, action: #selector(onRateButton), for: .touchUpInside)
        rateButton.isHidden = false
    }

// .....more

AutoLayout use SnapKit

self.player.replaceVideo(url)
        view.addSubview(self.player.displayView)

        self.player.play()
        self.player.backgroundMode = .proceed
        self.player.delegate = self
        self.player.displayView.delegate = self
        self.player.displayView.titleLabel.text = "China NO.1"
        self.player.displayView.snp.makeConstraints { [weak self] (make) in
            guard let strongSelf = self else { return }
            make.top.equalTo(strongSelf.view.snp.top)
            make.left.equalTo(strongSelf.view.snp.left)
            make.right.equalTo(strongSelf.view.snp.right)
            make.height.equalTo(strongSelf.view.snp.width).multipliedBy(3.0/4.0) // you can 9.0/16.0
        }

Background playback

• Project setting

• AppDelegate settings

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.
        do
        {
            try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
        }
        catch let error as NSError
        {
            print(error)
        }
        return true
    }

• VGPlayer Background playback mode to proceed

self.player.backgroundMode = .proceed

Delegate methods optional

// player delegate
    // play state
    func vgPlayer(_ player: VGPlayer, stateDidChange state: VGPlayerState)
    // playe Duration
    func vgPlayer(_ player: VGPlayer, playerDurationDidChange currentDuration: TimeInterval, totalDuration: TimeInterval)
    // buffer state
    func vgPlayer(_ player: VGPlayer, bufferStateDidChange state: VGPlayerBufferstate)
    // buffered Duration
    func vgPlayer(_ player: VGPlayer, bufferedDidChange bufferedDuration: TimeInterval, totalDuration: TimeInterval)
    // play error
    func vgPlayer(_ player: VGPlayer, playerFailed error: VGPlayerError)


// player view delegate
    /// fullscreen
    func vgPlayerView(_ playerView: VGPlayerView, willFullscreen fullscreen: Bool)
    /// close play view
    func vgPlayerView(didTappedClose playerView: VGPlayerView)
    /// displaye control
    func vgPlayerView(didDisplayControl playerView: VGPlayerView)
