Question

我在webview应用程序iOS swift中工作：

我面临的问题是我想获得webview显示的每个网址：

在网址上我必须执行一些if else检查。但我无法得到webview加载的网址。

webview正在显示精细结果并在点击时加载网址。我想获取webview导航的所有网址..

import Foundation
import UIKit


class seconVC: UIViewController {

    var toPass:String!
    var touser:String!
    var toPassing:String!



    @IBOutlet weak var webV: UIWebView!

    @IBOutlet weak var L_back: UIBarButtonItem!

    @IBOutlet weak var R_frwrd: UIBarButtonItem!

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.

        var domurl = toPass;

        var username = touser;

        var passwing = toPassing;



        var sendurl = stringA+username+"/"+passwing;

        //exchange login with auth/username/password
        println(sendurl);

        let url = NSURL (string: sendurl);


        let requestObj = NSURLRequest(URL: url!);
        webV.userInteractionEnabled = true
        webV.loadRequest(requestObj);



    }

    @IBAction func L_back(sender: UIBarButtonItem) {

        if (webV.canGoBack){
            webV.goBack()
        }


    }

    @IBAction func R_frwrd(sender: UIBarButtonItem) {

        if (webV.canGoForward){
            webV.goForward()
        }

    }



    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.


    }



}

我想要的是获取webview的当前网址和导航按钮的字符串：请帮忙吗？我提到所有的互联网没有解决方案在我的情况下工作。

Answer 1

有UIWebViewDelegate个shouldStartLoadWithRequest，例如webViewDidStartLoad或webViewDidFinishLoad或didFailLoadWithError或if let currentURL = webView.request?.url?.absoluteString{ print(currentURL) }可帮助您实现目标。如果要在视图完成后执行操作，请实现此委托方法

选项-1

let currentURL = webV.request.URL.absoluteString

选项-2

在委托方法中获取网址

func webViewDidFinishLoad(webView: UIWebView){ print(WebView.request?.mainDocumentURL) }

选项-3

func webViewDidFinishLoad(webView: UIWebView) { let currentURL = webView.request().URL() print("\(currentURL.description)") }

或使用

func webViewDidFinishLoad(webView: UIWebView){ let currentURL = webView.request?.URL }

选项-4

func webViewDidFinishLoad(webView: UIWebView) { let currentURL: = webView.stringByEvaluatingJavaScriptFromString("window.location.href")! print("\(currentURL)") }

选项-5

func webView(webview: UIWebView, shouldStartLoadWithRequest request: NSURLRequest, navigationType: UIWebViewNavigationType) -> Bool { let currentURL = request.URL.absoluteString print("\(currentURL)") }

选项-6

func webViewDidFinishLoad(WebVie: UIWebView) { let currentURL = WebVie.request.mainDocumentURL print("\(currentURL)") }

Answer 3

首先，您必须定义WebView类的委托。 “ WebView.delegate =自我”。将此代码添加到上述功能之一旁边：

override func viewDidLoad() {
    super.viewDidLoad()
    myWebView.delegate = self  }

，例如：

func webViewDidFinishLoad(_ webView: UIWebView) {
    if let currentURL = WebView.request?.url?.absoluteString{
        print(currentURL)
    }
}

iOS Swift：无法检索UIwebView中加载的当前url
