Question

我有一个拥有UIWebView的应用程序，而Webview包含简单的按钮

这是我的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);
    }
}

webView完美显示我的HTML

当我单击HTML文件中的按钮时，我只需要从我的iOS项目中呈现一个newViewController？

像那样：

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

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

}



</script>

有没有办法在iOS中做到这一点？

Answer 1

您可以在js操作中指定方案：

window.location = yourscheme://<scheme_content>

在swift层中你可以使用回调：

func webView(webView: UIWebView!, shouldStartLoadWithRequest request: NSURLRequest!, navigationType: UIWebViewNavigationType) -> Bool {
    if (request.URL.scheme == "yourscheme") {
        // Your code
    }
    return true;
}

Answer 2

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
    }
