swift youtube player 使用心得

1:youtube player可以通过id 或url来播放视频

主要用到的两个方法是 loadWithVideoId 和 loadVideoByURL

这两者的区别是 loadVideoByURL加载完之后会自动播放的

loadWithVideoId不会自动播放加载完之后会显示第一政的图和一个播放按钮

2：通过url获取id的重点实现方法如下：

private extension NSURL {
    func queryStringComponents() -> [String: AnyObject] {

        var dict = [String: AnyObject]()

        // Check for query string
        if let query = self.query {

            // Loop through pairings (separated by &)
            for pair in query.componentsSeparatedByString("&") {

                // Pull key, val from from pair parts (separated by =) and set dict[key] = value
                let components = pair.componentsSeparatedByString("=")
                if (components.count > 1) {
                    dict[components[0]] = components[1]
                }
            }

        }

        return dict
    }
}

public func videoIDFromYouTubeURL(videoURL: NSURL) -> String? {
        if let host = videoURL.host, pathComponents = videoURL.pathComponents where pathComponents.count > 1 && host.hasSuffix("youtu.be") {
            return pathComponents[1]
        }
        return videoURL.queryStringComponents()["v"] as? String
    }
