ios - 为 UIWebView 拦截 UITapGestureRecognizer

Question

我想弄清楚如何拦截 UIWebView 上的点击事件。似乎正确的手势是 UITapGestureRecognizer，但我似乎无法获得正确的 View 。我一直无法快速找到解决方案。我的层次结构是 View -> UIWebView。我的用例是部署一个网络应用程序，并有一些基于 WebView 导航的自定义操作。例如，能够识别我想要转换插页式广告或显示 UINavigationBar 的导航事件。感谢您的帮助!

import UIKit

class ViewController: UIViewController {

   @IBOutlet var Webview: UIWebView!

   let URLPath = "http://www.example.com"

   func loadAddressURL(){

       let requestURL = NSURL(string: URLPath)
       let request = NSURLRequest(URL: requestURL!)
       Webview.loadRequest(request)

   }

   override func viewDidLoad() {
       super.viewDidLoad()

       loadAddressURL()
       NSLog("I'm getting going")        

       //NOT SURE IF YOU SHOULD DISABLE THIS OR NOT
       //Webview.userInteractionEnabled=false


       let tapRecognizer = UITapGestureRecognizer(target: self , action: "handleSingleTap:")
       NSLog("I'm past the tab recognizer!\(tapRecognizer)")

       tapRecognizer.numberOfTapsRequired = 1
       Webview.addGestureRecognizer(tapRecognizer)
   }

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

   func handleSingleTap(recognizer: UITapGestureRecognizer) {
       //
       NSLog("I made it here")
   }   

}

先设置GestureDelegate并继承getureUIGestureRecognizerDelegate

tapRecognizer.delegate = self

并插入这个代表

func gestureRecognizer(UIGestureRecognizer,  shouldRecognizeSimultaneouslyWithGestureRecognizer:UIGestureRecognizer) -> Bool 
{
    return true
}

试试这个也许很有帮助...
