ios - 我如何使用 Youtube iOS API 查找、转到某一秒？

Question

我在这里玩过 YouTube-Player-iOS-Helper:https://github.com/youtube/youtube-ios-player-helper

但我不知道如何从某一秒开始将视频嵌入到 iOS 应用程序中，有什么想法吗？

如你所见，我已经尝试过了

1. 添加一个 HTML5 键值对 "start": 100，但它崩溃了
2. 并尝试在视频加载后搜索，pv.seekToSeconds(100, allowSeekAhead: true) 但也没有效果

===

class ViewController: UIViewController {

    @IBOutlet weak var pv: YTPlayerView!
    override func viewDidLoad() {
        super.viewDidLoad()


        pv.loadWithVideoId("M7lc1UVf-VE", playerVars: ["controls": 0, "playsinline": 1, "autohide": 1, "showinfo": 0, "modestbranding": 1]) //, "start": 100
        NSNotificationCenter.defaultCenter().addObserver(self, selector: "receivedPlaybackStartedNotification:", name: "Playback started", object: nil)
    }

    func receivedPlaybackStartedNotification(notification: NSNotification) {

        pv.seekToSeconds(100, allowSeekAhead: true)
    }
}

您需要等待 playerViewDidBecomeReady 委托(delegate)被调用。

在 Swift 中，这是:

class MyViewVc: UIViewController, YTPlayerViewDelegate {

    @IBOutlet weak var ytPlayer: YTPlayerView!

    override func viewDidLoad() {
        super.viewDidLoad()

        self.ytPlayer.delegate = self

        self.ytPlayer.load(withVideoId: "M7lc1UVf-VE")        
    }

    func playerViewDidBecomeReady(_ playerView: YTPlayerView) {
        self.ytPlayer.seek(toSeconds: 100, allowSeekAhead: true)
    }
}
