这段代码很快2

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    let playerViewController = segue.destination as! PlayerViewController
    playerViewController.videoID = channelsDataArray[selectedVideoIndex]["videoID"] as! String   
}

错误"方法不会覆盖其超类中的任何方法"

请快速解决方案3

当我在我的代码中使用日语时

func getChannelDetails(useChannelIDParam: Bool) {
    var urlString: String!
    if !useChannelIDParam {
        urlString = "https://www.googleapis.com/youtube/v3/search?part=snippet%2Cid&maxResults=50&order=viewCount&q=????GO&key=\(apikey)"
    }

我遇到了问题
