iOS Swift：不能检索当前在UIwebView中加载的URL

我在webview应用程序iOS swift中工作：

我面临的问题是我想要获取每个网页显示的url：

在url上，我必须执行一些其他检查。 但我无法得到WebView加载的url。

webview显示效果很好，点击后加载url。 我想获取所有的Web浏览器的导航

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. } } 

我想要的是为webview获取当前的url和导航button的string：请帮忙？ 我提到所有的互联网没有解决scheme在我的情况下工作。

Answer 1

有几个UIWebViewDelegate ，如shouldStartLoadWithRequest或webViewDidStartLoad或webViewDidFinishLoad或didFailLoadWithError ，可以帮助您实现您的目标。 如果要在视图完成后执行操作，则执行此委托方法

// Swift 3

如果让currentURL = webView.request？.url？.absoluteString {print（currentURL）}

就像这里提到的那样。

选项1

 let currentURL = webV.request.URL.absoluteString 

选项2

在委托方法中获取URL

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

选项-3

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

或者使用像

  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)") }
