WKUIDelegate -> delegate 등록 시켜주고
@IBOutlet weak var webKitView: WKWebView!
override func viewDidLoad() {
super.viewDidLoad()
webKitView.uiDelegate = self
}
// java alert
func webView(_ webView: WKWebView, runJavaScriptAlertPanelWithMessage message: String, initiatedByFrame frame: WKFrameInfo, completionHandler: @escaping () -> Void) {
print("message ->\(message)")
self.showToast(message: message)
completionHandler()
}
completionHandler() 꼭 해야 한다... 않하면
runJavaScriptAlertPanelWithMessage:initiatedByFrame was not called -> 이런 이슈가 나온다
