ios - iOS 中的自定义 View 类未调用委托(delegate)事件

Question

我正在尝试使用

播放 YouTube 视频

Swift-Youtube-Player

目前我遇到了委托(delegate)方法未被调用的问题。

我已经创建了从 IB 到该播放器的导出，但由于某种原因我无法将委托(delegate)从 IB 拖动到 View Controller ，因此我尝试在代码中执行此操作。

这是我尝试过的:

@IBOutlet weak var youtubePlayer: YouTubePlayerView!

    var _currentYoutubeId: String = "";

    override func viewDidLoad() {
        super.viewDidLoad()
        print(_currentYoutubeId)
        youtubePlayer.delegate = self
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    func playerReady(videoPlayer: YouTubePlayerView) {
        print(videoPlayer)
        if youtubePlayer.ready {
            youtubePlayer.playerVars = [
                "playsinline": "1",
                "controls": "0",
                "showinfo": "0"
            ]
            youtubePlayer.loadVideoID(_currentYoutubeId)
            if youtubePlayer.playerState != YouTubePlayerState.Playing {
                youtubePlayer.play()
            } else {
                youtubePlayer.pause()
            }
        }

    }

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

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

我正在最新的 XCode 版本中执行此操作，并且我对 iOS、Swift 和 Apple 相关的所有内容都很陌生。

具体来说，我的问题是如何将此委托(delegate)连接到播放器以便调用其生命周期方法？

编辑:我之前已经使用 UICollectionViewDelegate 成功做到了这一点，但我还没有成功使用这个自定义 View 。

Answer 1

这就是我使用 Swift-Youtube-Player 的方式。

class videoController: UIViewController, YouTubePlayerDelegate {
@IBOutlet var videoPlayer: YouTubePlayerView!
var videoID: String?

override func viewDidLoad() {
    super.viewDidLoad()

    videoPlayer.delegate = self

    if let videoID = self.videoID {
        videoPlayer.loadVideoID(videoID)
    }
}

func playerReady(videoPlayer: YouTubePlayerView) {
    videoPlayer.play()
}

func playerStateChanged(videoPlayer: YouTubePlayerView, playerState: YouTubePlayerState) {
    if videoPlayer.playerState == YouTubePlayerState.Ended || videoPlayer.playerState == YouTubePlayerState.Paused {
        //Your code here
    } 
}

func playerQualityChanged(videoPlayer: YouTubePlayerView, playbackQuality: YouTubePlaybackQuality) {
    //Your code here
}

}
