ios - WKWebView加载后6秒显示警报

Question

我有这个但不确定如何在WKWebView加载后设置6秒的计时器。我有这个代表didFinish navigation。我认为这行不通:

func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
    showAlert()
}

func showAlert() {
    let alert = UIAlertController(title: "Loaded ", message: "In webview currently", preferredStyle: UIAlertController.Style.alert)
    self.present(alert, animated: true, completion: nil)
}

Answer 1

您可以为此使用DispatchQueue asyncAfter。它在指定的截止日期之后执行操作。以下是您的解决方案。

func showAlert() {
    let alert = UIAlertController(title: "Loaded ", message: "In webview currently", preferredStyle: .alert)
    DispatchQueue.main.asyncAfter(deadline: .now()+6.0) {
        self.present(alert, animated: true, completion: nil)
    }
}
