Question

我正在使用框架在Swift中播放Youtube视频：https://github.com/gilesvangruisen/Swift-YouTube-Player。该框架提供了委托方法，但我似乎无法解决它们。其他人已经开始工作了，所以我确定问题就在我身边。

import UIKit
import YouTubePlayer

class MainPlayerController: UIViewController, YouTubePlayerDelegate {

@IBOutlet var playerView: YouTubePlayerView!

override func viewDidLoad() {
    super.viewDidLoad()
    let myVideoURL = NSURL(string: "https://www.youtube.com/watch?v=OGe-WXhbmBg")
    playerView.delegate = self
    playerView.loadVideoURL(myVideoURL! as URL)
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
}

@IBAction func play(_ sender: AnyObject) {
    playerView.play()
}


//The 3 functions below will not fire

func playerStateChanged(videoPlayer: YouTubePlayerView, playerState: YouTubePlayerState) {
    print("playerStateChanged")
}

func playerReady(videoPlayer: YouTubePlayerView) {
    print("playerReady")
}

func playerQualityChanged(videoPlayer: YouTubePlayerView, playbackQuality: YouTubePlaybackQuality) {
    print("playerQualityChanged")
}


}

播放器工作正常并将播放。我试图让playerReady（）函数特别有效。任何帮助都会很棒，谢谢。
