Launching phone/email/map links in WKWebView

Question

KINWebBrowser is an open source web browser module for iOS apps. I recently upgraded KINWebBrowser to use WKWebView to begin phasing out UIWebView. This yields significant improvements, but:

Problem: WKWebView does not enable users to launch links containing URLs for phone numbers, email address, maps, etc.

How can I configure a WKWebView to launch the standard iOS behaviors for these alternate URLs when launched as links from the displayed page?

All of the code is available here

Answer 1

I was able to get it to work for the Google Maps link (which appears to be related to the target="_blank") and for the tel: scheme by adding this function to your KINWebBrowserViewController.m

- (void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction decisionHandler:(void (^)(WKNavigationActionPolicy))decisionHandler {     if(webView != self.wkWebView) {         decisionHandler(WKNavigationActionPolicyAllow);         return;     }      UIApplication *app = [UIApplication sharedApplication];     NSURL         *url = navigationAction.request.URL;      if (!navigationAction.targetFrame) {         if ([app canOpenURL:url]) {             [app openURL:url];             decisionHandler(WKNavigationActionPolicyCancel);             return;         }     }     if ([url.scheme isEqualToString:@"tel"])     {         if ([app canOpenURL:url])         {             [app openURL:url];             decisionHandler(WKNavigationActionPolicyCancel);             return;         }     }     decisionHandler(WKNavigationActionPolicyAllow); }

Works on xcode 8.1, Swift 2.3.

For target="_blank", phone number (tel:) and email (mailto:) links.

func webView(webView: WKWebView, decidePolicyForNavigationAction navigationAction: WKNavigationAction, decisionHandler: (WKNavigationActionPolicy) -> Void) {     if webView != self.webview {         decisionHandler(.Allow)         return     }      let app = UIApplication.sharedApplication()     if let url = navigationAction.request.URL {         // Handle target="_blank"         if navigationAction.targetFrame == nil {             if app.canOpenURL(url) {                 app.openURL(url)                 decisionHandler(.Cancel)                 return             }         }          // Handle phone and email links         if url.scheme == "tel" || url.scheme == "mailto" {             if app.canOpenURL(url) {                 app.openURL(url)                 decisionHandler(.Cancel)                 return             }         }          decisionHandler(.Allow)     } } 

Updated for swift 4.0

func webView(_ webView: WKWebView, decidePolicyFor navigationAction: WKNavigationAction, decisionHandler: @escaping (WKNavigationActionPolicy) -> Void) {      if webView != self.webView {         decisionHandler(.allow)         return     }      let app = UIApplication.shared     if let url = navigationAction.request.url {         // Handle target="_blank"         if navigationAction.targetFrame == nil {             if app.canOpenURL(url) {                 app.open(url)                 decisionHandler(.cancel)                 return             }         }          // Handle phone and email links         if url.scheme == "tel" || url.scheme == "mailto" {             if app.canOpenURL(url) {                 app.open(url)             }              decisionHandler(.cancel)             return         }          decisionHandler(.allow)     }  }
