我正在尝试学习如何使用WKWebView,但是我遇到了一个问题,即任何电话号码链接实际上都不会显示用于呼叫该号码的弹出窗口。
我遵循了this的回答,下面列出了打印错误。我正在使用的网站是一个使用quickactionbar的wix网站(我知道它使用tel:xxxxx,因为它可以在safari中工作,所以应该可以正常工作)。为什么要这样做?
编辑: 另外,我不确定要搜索什么才能获得所需的答案。如果您确切地知道要搜索什么才能找到答案,我也会对此感到满意。
如果我长按它会识别出它是一个电话号码,但是只要我轻按它就不会做任何事情
import Foundation
import WebKit
class WebKitViewController: UIViewController, WKUIDelegate, WKNavigationDelegate {
var webView: WKWebView!
@IBOutlet weak var backButton: UIBarButtonItem!
@IBAction func backButtonAction(_ sender: UIBarButtonItem) {
if self.webView.canGoBack {
self.webView.goBack()
}
}
override func loadView() {
let webConfiguration = WKWebViewConfiguration()
webView = WKWebView(frame: .zero, configuration: webConfiguration)
webView.uiDelegate = self
webView.navigationDelegate = self
view = webView
}
override func viewDidLoad() {
super.viewDidLoad()
let myURL = URL(string: "Link")
let myRequest = URLRequest(url: myURL!)
webView.load(myRequest)
}
// func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
// backButton.isEnabled = webView.canGoBack
// }
//Code from answer on StackOverflow
func webView(_ webView: WKWebView, didStartProvisionalNavigation navigation: WKNavigation) {
UIApplication.shared.isNetworkActivityIndicatorVisible = true
print("didStartProvisionalNavigation: \(navigation)")
}
func webView(_ webView: WKWebView, didReceiveServerRedirectForProvisionalNavigation navigation: WKNavigation) {
print("didReceiveServerRedirectForProvisionalNavigation: \(navigation)")
}
func webView(_ webView: WKWebView, didFailProvisionalNavigation navigation: WKNavigation, withError error: Error) {
print("didFailProvisionalNavigation: \(navigation), error: \(error)")
}
func webView(_ webView: WKWebView, didFinishLoading navigation: WKNavigation) {
UIApplication.shared.isNetworkActivityIndicatorVisible = false
print("didFinishLoadingNavigation: \(navigation)")
}
func _webViewWebProcessDidCrash(_ webView: WKWebView) {
print("WebContent process crashed; reloading")
}
func webView(_ webView: WKWebView,createWebViewWith configuration: WKWebViewConfiguration, for navigationAction: WKNavigationAction, windowFeatures: WKWindowFeatures) -> WKWebView?{
//if <a> tag does not contain attribute or has _blank then navigationAction.targetFrame will return nil
if let trgFrm = navigationAction.targetFrame {
if(!trgFrm.isMainFrame){
UIApplication.shared.isNetworkActivityIndicatorVisible = true
self.webView.load(navigationAction.request)
}
}
return nil
}
func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!){
UIApplication.shared.isNetworkActivityIndicatorVisible = false
print("didFinish: \(String(describing: self.webView.url)); stillLoading:\(self.webView.isLoading ? "NO" : "YES")")
}
func webView(_ webView: WKWebView, decidePolicyFor navigationResponse: WKNavigationResponse, decisionHandler: @escaping (_: WKNavigationResponsePolicy) -> Void) {
print("decidePolicyForNavigationResponse")
decisionHandler(.allow)
}
func webView(_ webView: WKWebView, decidePolicyFor navigationAction: WKNavigationAction, decisionHandler: @escaping (_: WKNavigationActionPolicy) -> Void) {
decisionHandler(.allow)
}
}
错误:
didFailProvisionalNavigation: <WKNavigation: 0x101865bd0>, error: Error Domain=NSURLErrorDomain Code=-1002 "unsupported URL" UserInfo={_WKRecoveryAttempterErrorKey=<WKReloadFrameErrorRecoveryAttempter: 0x101856b80>, NSErrorFailingURLStringKey=tel:+12199874536, NSErrorFailingURLKey=tel:+12199874536, NSLocalizedDescription=unsupported URL, NSUnderlyingError=0x1018641a0 {Error Domain=kCFErrorDomainCFNetwork Code=-1002 "(null)"}}
答案 0 :(得分:4)
您还可以在WKWebViewConfiguration上将dataDetectorTypes设置为.phoneNumber。检测到的所有电话号码都会转换为包含电话号码周围的链接。
configuration.dataDetectorTypes = .phoneNumber
使用该脱盐功能-
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)
}
}
