swift 遇到了问题

    let documentsDir = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true).last
     qnPlayer = QPlayerView.init(frame: CGRect(x: 0, y: 0, width: videoView.width, height: videoView.height), appVersion: "", localStorageDir: documentsDir!, logLevel: .LOG_VERBOSE)
    self.videoView.addSubview(qnPlayer!)
    qnPlayer!.controlHandler.forceAuthenticationFromNetwork()
    let qMediaModel = QMediaModel.init(false)
    qMediaModel.addStreamElements("", urlType: QPlayerURLType.QURL_TYPE_NONE, url: "http://demo-videos.qnsdk.com/qiniu-720p.mp4", quality: 720, isSelected: true, backupUrl: "", referer: "", renderType: QPlayerRenderType.QPLAYER_RENDER_TYPE_PLANE )

// qMediaModel.isLive = false
self.qnPlayer!.controlHandler.playMediaModel(pmediaModel: qMediaModel, startPos: 0)

代码是这样写的，videoView一直没有反应，看不太懂oc代码，望大佬指点下

你好，鉴权成功了么？bundleID 是否获得了基础播放的权利
