iOS版雨燕：不能檢索的UIWebView

Question

加載當前URL

我在WebView中應用的iOS快捷的工作：

問題我面臨的是我想它的WebView顯示每個網址：網址時

我必須執行一些其他檢查。但我無法獲得webview加載的url。

webview在單擊時顯示出良好的結果並加載網址。我要取的網頁視圖導航在所有網址..

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. 


    } 



} 

所有我想要的是得到的WebView當前URL和導航按鈕的字符串：請幫助？我提到所有的互聯網沒有解決方案在我的情況下工作。
