javascript - swift -通过单击UIWebView中的按钮来打开ViewController

我有一个名为“ test123”的ViewController，并且我有一个带有按钮的UIWebView：

<button onclick='myFunction()'>Open test123</button>
</body>

<script>
    function myFunction()
    {
        presentViewController('test');

    }
    </script>

我尝试了this但得到了Use of undeclared type 'test123'

func webView(webView: UIWebView, shouldStartLoadWithRequest request: NSURLRequest, navigationType: UIWebViewNavigationType) -> Bool {

    if (navigationType == UIWebViewNavigationType.formSubmitted) {
        let VC = self.storyboard?.instantiateViewControllerWithIdentifier("test123") as? test123

        let navigationController = UINavigationController(rootViewController: VC!)
        self.navigationController?.presentViewController(navigationController, animated: true, completion:nil)


    }
    return true
}

那我在做什么错？

最佳答案

您应该删除试图将对象转换为显然不存在的类型的as? test123的test123部分。
