在WKWebView中启动电话/电子邮件/地图链接 [英] Launching phone/email/map links in WKWebView

问题描述

KINWebBrowser 是iOS应用程式的开放原始码网路浏览器模组。我最近升级了KINWebBrowser，以使用 WKWebView 开始逐步淘汰UIWebView。这产生了显着的改进，但是：

问题：WKWebView不允许用户启动包含电话号码，电子邮件地址，地图等URL的链接。

如何配置WKWebView，以便从显示的页面以链接形式启动这些备用网址的标准iOS行为？

所有代码都可在此处

解决方案

我能够得到它通过将此函数添加到您的KINWebBrowserViewController.m

<$ p，工作Google地图链接（看起来与target =_ blank相关）和tel： $ p> - （void）webView：（WKWebView *）webView decisionPolicyForNavigationAction：（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）;
}


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?

解决方案

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);
}
