是WKCompositingView攔截觸摸嗎？

我有一個WKWebView，我想處理觸摸，但我無法找到正確的方法。是WKCompositingView攔截觸摸嗎？

webView是以編程方式在viewDidLoad中創建的，並且加載正常。

override func viewDidLoad() { 
    super.viewDidLoad() 
    let site = "http://google.com" 
    let url = URL(string: site) 
    let request = URLRequest(url: url!) 
    webView = WKWebView(frame: self.view.frame) 
    webView.navigationDelegate = self 
    webView.uiDelegate = self // is this necessary for UITouch recognition? 
    webView.load(request) 
    self.view.addSubview(webView) 
}

我已經嘗試在viewDidLoad中添加UITapGestureRecognizer ...（每UIWebView and touch event）

override func viewDidLoad() { 
    //... 
    let taprecognizer = UITapGestureRecognizer(target: self, action: #selector(tapLocation)) 
    taprecognizer.numberOfTapsRequired = 1 
    taprecognizer.delegate = self 
    webView.addGestureRecognizer(taprecognizer) 
} 

func tapLocation(recognizer: UITapGestureRecognizer, shouldRecognizeSimultaneouslyWith otherGestureRecognizer: UIGestureRecognizer) -> Bool { 
    print("tapped") 
    return true 
}

我也試着從獲得觸摸...

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) { 
    print("tapped") 
}

我的Debug視圖層次結構顯示了一堆WKCompositingViews，這讓我認爲這些在使用觸摸之前可以到達WKWebView或View。

我添加的UIViewController，UIWebViewDelegate，WKNavigationDelegate，WKUIDelegate，UIGestureRecognizerDelegate上課...但它只是不會去。

是你能解決這個問題問題？ – glo

你的意思是你想在'WKWebView'中處理觸摸，或者你想處理WebView中的鏈接？ – Jaydeep

@Superman我試圖處理在'WKWebview'範圍內發生的觸摸。我相信我這樣做是爲了使用鏈接，但我學會了使用'evaluateJavaScript'來代替，所以我仍然找到了解決此問題的方法。 – Dustin

下面是我在其中加入WKWebView到主視圖中的樣本工作代碼和我能夠檢測出使用UIGestureRecognizerDelegate

      let taprecognizer = UITapGestureRecognizer(target: self, action: #selector(tapLocation)) 
      taprecognizer.numberOfTapsRequired = 1 
      taprecognizer.numberOfTouchesRequired = 1 
      taprecognizer.delegate = self 
      webView.addGestureRecognizer(taprecognizer) 
     } 

     @objc func tapLocation(recognizer: UITapGestureRecognizer, shouldRecognizeSimultaneouslyWith otherGestureRecognizer: UIGestureRecognizer) -> Bool { 
      print("tapped") 
      return true 
     } 

     func gestureRecognizerShouldBegin(_ gestureRecognizer: UIGestureRecognizer) -> Bool { 
      print("Tap event will detect here.") 
      return true 
     } 

    }
