WKWebView 不会打开外部链接

【中文标题】WKWebView 不会打开外部链接【英文标题】：WKWebView won't open external links 【发布时间】：2016-03-28 05:05:15 【问题描述】：所以我正在将我的 UIWebView 应用程序转换为 WKWebView 只是发现它不会打开外部网站，即 dropbox、facebook 等。
它会在 viewDidLoad 中加载我的网站，所以这不是问题。
示例：
NSURL *nsurl=[NSURL URLWithString:@"example.com"];
NSURLRequest *nsrequest=[NSURLRequest requestWithURL:nsurl];
[webView loadRequest:nsrequest];
webView.navigationDelegate = self;
webView.UIDelegate = self;
[self.view addSubview:webView];
我打过电话：
-(void)webView:(WKWebView *)webView didStartProvisionalNavigation: (WKNavigation *)navigation
- (void)webView:(WKWebView *)webView didFinishNavigation: (WKNavigation *)navigation
还有：
- (void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction decisionHandler:(void (^)(WKNavigationActionPolicy))decisionHandler
decisionHandler(WKNavigationActionPolicyAllow);
最后在我的 info.plist 中我添加了：
<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
<key>NSExceptionAllowsInsecureHTTPLoads</key>
<true/>
<key>NSIncludesSubdomains</key>
<true/>
<key>NSThirdPartyExceptionAllowsInsecureHTTPLoads</key>
<true/>
</dict>
但没有任何效果。我做错了什么？
我们将一如既往地为您提供任何帮助。

【参考方案1】：好的，所以我设法得到了它，以及一些被遗忘的网站的帮助（抱歉），我设法让这一切正常工作。
下面是我在 webview 中使用的几乎所有内容。
//Webview Start/Finish Request
- (void)webView:(WKWebView *)webView didStartProvisionalNavigation:(WKNavigation *)navigation
[UIApplication sharedApplication].networkActivityIndicatorVisible = YES;
NSLog(@"didStartProvisionalNavigation: %@", navigation);
- (void)webView:(WKWebView *)webView didReceiveServerRedirectForProvisionalNavigation:(WKNavigation *)navigation
NSLog(@"didReceiveServerRedirectForProvisionalNavigation: %@", navigation);
- (void)webView:(WKWebView *)webView didFailProvisionalNavigation:(WKNavigation *)navigation withError:(NSError *)error
NSLog(@"didFailProvisionalNavigation: %@navigation, error: %@", navigation, error);
- (void)webView:(WKWebView *)webView didCommitNavigation:(WKNavigation *)navigation
NSLog(@"didCommitNavigation: %@", navigation);
- (void)webView:(WKWebView *)webView didFinishLoadingNavigation:(WKNavigation *)navigation
[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
NSLog(@"didFinishLoadingNavigation: %@", navigation);
- (void)webView:(WKWebView *)webView didFailNavigation:(WKNavigation *)navigation withError:(NSError *)error
NSLog(@"didFailNavigation: %@, error %@", navigation, error);
- (void)_webViewWebProcessDidCrash:(WKWebView *)webView
NSLog(@"WebContent process crashed; reloading");
- (WKWebView *)webView:(WKWebView *)webView createWebViewWithConfiguration:(WKWebViewConfiguration *)configuration forNavigationAction:(WKNavigationAction *)navigationAction windowFeatures:(WKWindowFeatures *)windowFeatures
if (!navigationAction.targetFrame.isMainFrame)
[UIApplication sharedApplication].networkActivityIndicatorVisible = YES;
[self.webView loadRequest:navigationAction.request];
return nil;
- (void)webView:(WKWebView *)webView didFinishNavigation: (WKNavigation *)navigation
[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
NSLog(@"didFinish: %@; stillLoading:%@", [self.webView URL], (self.webView.loading?@"NO":@"YES"));
- (void)webView:(WKWebView *)webView decidePolicyForNavigationResponse:(WKNavigationResponse *)navigationResponse decisionHandler:(void (^)(WKNavigationResponsePolicy))decisionHandler
NSLog(@"decidePolicyForNavigationResponse");
decisionHandler(WKNavigationResponsePolicyAllow);
- (void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction decisionHandler:(void (^)(WKNavigationActionPolicy))decisionHandler
if (decisionHandler)
decisionHandler(WKNavigationActionPolicyAllow);
所以我帮助所有这些帮助某人。

【参考方案2】：这是这个答案的 swift 3.0 版本 添加这两个代表
// webView is WKWebview object
webView.navigationDelegate = self;
webView.uiDelegate = self;
覆盖这些委托回调方法
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)
【讨论】：
【参考方案3】：请检查此方法的返回类型，
- (WKWebView *)webView:(WKWebView *)webView createWebViewWithConfiguration:(WKWebViewConfiguration *)configuration forNavigationAction:(WKNavigationAction *)navigationAction windowFeatures:(WKWindowFeatures *)windowFeatures
if (!navigationAction.targetFrame.isMainFrame)
[self.webView loadRequest:navigationAction.request];
return self.webView;
因为它是 WKWebView，如果你返回你的 webview，它会为你加载 URL 并给你想要显示的页面。
