在WKWebView中显示“使用相机”选项

Question

I'm implementing a WKWebView that loads a payment page with credit card information; I need to show the 'Use camera' option along with the keyboard just like safari browser.

I have added the camera permission for the info.plist, but nothing is working on the webview!! Should I select a specific keyboard?

I am using iOS 11 with swift 3.2 or 4.0

Here it is my code

    var webView : WKWebView = WKWebView()
    let configuration = WKWebViewConfiguration()   
    webView = WKWebView(frame: CGRect.zero, configuration: configuration)      
    webView.frame = CGRect(x: 0, y: 20, width: self.view.bounds.width, height: self.view.bounds.height)       
    webView.navigationDelegate = self
    webView.uiDelegate = self
    webView.scrollView.delegate = self
    webView.backgroundColor = UIColor.black
    webView.isMultipleTouchEnabled = false
    self.view.addSubview(webView)

    let newurl = URL(string:"https://xxxxxxxxx")
    let newrequest = URLRequest(url: newurl!)                    
    self.webView.load(newrequest)

plus Camera permission

Key       :  Privacy - Camera Usage Description   
Value     :  $(PRODUCT_NAME) Use camera

After long research I found SFSafariViewController with its delegate class SFSafariViewControllerDelegate could be used to show the scan card option available on safari, but with limited capabilities compared to the WKWebView, so it's up to your business case to use it or not, but anyway this is the only option available right now according to my knowledge.

Please note that, in order to make it work, you should enable the scan card option on your mobile by changing the settings under the privacy.

Also, you need to be sure that the payment page includes the iOS meta tags to let safari detect the credit card fields.
