当我尝试从表格视图到网页视图（对于youtube视频）执行segue时遇到错误。我为代码附加了代码，错误和控制台的目标输出。这似乎是WKWebView类的一个问题...但我没有得到任何与此相关的错误。
发信人：
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let partyRock = partyRocks[indexPath.row]
performSegue(withIdentifier: "VideoVC", sender: partyRock)
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if let destination = segue.destination as? VideoVC {
if let party = sender as? PartyRock {
destination.partyRock = party
}
}
}
目的地：
import UIKit
class VideoVC: UIViewController {
@IBOutlet weak var webView: UIWebView!
@IBOutlet weak var titleLbl: UILabel!
private var _partyRock: PartyRock!
var partyRock: PartyRock {
get {
return _partyRock
} set {
_partyRock = newValue
}
}
override func viewDidLoad() {
super.viewDidLoad()
titleLbl.text = partyRock.videoTitle
webView.loadHTMLString(partyRock.videoURL, baseURL: nil)
}
}
控制台输出：
