I have a WKWebView that I want to ask to call a number when the number is selected. The contents of the web view contain the HTML anchor tag "tel:" and i am looking for a way to catch it. Which function is used to catch these tags?

推荐答案

设置webView的navigationDelegate属性并实现委托的以下功能( WKNavigationDelegate )

Set the webView's navigationDelegate property and implement the following function of the delegate (WKNavigationDelegate)

func webView(_ webView: WKWebView, decidePolicyFor navigationAction: WKNavigationAction, decisionHandler: @escaping (WKNavigationActionPolicy) -> Swift.Void) {
    if navigationAction.request.url?.scheme == "tel" {
        UIApplication.shared.openURL(navigationAction.request.url!)
        decisionHandler(.cancel)
    } else {
        decisionHandler(.allow)
    }
}

从iOS 10开始，您还可以在WKWebViewConfiguration上将dataDetectorTypes设置为.phoneNumber.所有检测到的电话号码都将转换为包含电话号码周围的链接，因此，在点击电话号码时，将使用具有"tel"方案的URL触发上述功能.

Since iOS 10, you can also set dataDetectorTypes to .phoneNumber on your WKWebViewConfiguration. All detected phone numbers will transformed to contain links around the phone number and thus the above function will be fired with a URL with a "tel" scheme when tapping on a phone number.

configuration.dataDetectorTypes = .phoneNumber
