当点击UIWebView中的按钮时打开ViewController [英] Opening ViewController when click on button in UIWebView swift

问题描述

我有一个具有UIWebView的应用程序，并且Webview包含简单的按钮

I Have an app which has UIWebView and the Webview contains simple Button

以下是我的WebViewController：

and here's my WebViewController :

import UIKit

class testViewController: UIViewController {
    internal static var testID = 0

    @IBOutlet weak var myWebView: UIWebView!
    override func viewDidLoad() {
        super.viewDidLoad()

    }

    override func viewDidAppear(animated: Bool) {
        super.viewDidAppear(animated)

        let url = NSURL (string: "http://mydomainname/index.html");
        let requestObj = NSURLRequest(URL: url!);
        myWebView.loadRequest(requestObj);
    }
}

而webView完美显示我的HTML

And the webView displaying my HTML perfectly

当我点击HTML文件中的按钮时，我只需要从我的iOS项目中提供一个newViewController？

I am just need to present a newViewController from my iOS project when i Click the button in my HTML file ?

这样：

like that :

<button onclick="myFunction()> Submit </button>

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

}



</script>

有没有办法在iOS中做到这一点？

is there any way to do that in iOS ?

推荐答案

是的，你可以这样做：

func webView(webView: UIWebView, shouldStartLoadWithRequest request: NSURLRequest, navigationType: UIWebViewNavigationType) -> Bool {
        
        if (navigationType == UIWebViewNavigationType.FormSubmitted) {
            let VC = self.storyboard?.instantiateViewControllerWithIdentifier("myViewControllerName") as? myViewControllerName

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

    
        }
        return true
    }
