wkwebview 重定向处理新开窗口问题
方法一：网页里面target的值置为空- (void)webView:(WKWebView )webView decidePolicyForNavigationAction:(WKNavigationAction )navigationAction decisionHandler:(void (^)(WKNavigationActionPolicy))decisionHandler{ if (!navigationAction.targetFrame.isMainFrame) { [webView evaluateJavaScript:@"var a = document.getElementsByTagName('a');for(var i=0;i<a.length;i++){a[i].setAttribute('target','');}" completionHandler:nil]; } decisionHandler(WKNavigationActionPolicyAllow);}方法二：KNavigationAction 中有两个属性：sourceFrame和targetFrame，分别代表这个action的出处和目标。类型是 WKFrameInfo 。WKFrameInfo有一个 mainFrame 的属性，正是这个属性标记着这个frame是在主frame里还是新开一个frame。- (void)webView:(WKWebView)webView decidePolicyForNavigationAction:(WKNavigationAction)navigationAction decisionHandler:(void(^)(WKNavigationActionPolicy))decisionHandler{ if(navigationAction.targetFrame==nil){ [webViewloadRequest:navigationAction.request]; } decisionHandler(WKNavigationActionPolicyAllow);}方法三：wkwebview 自带的WKUIDelegate代理方法- (WKWebView)webView:(WKWebView)webView createWebViewWithConfiguration:(WKWebViewConfiguration)configuration forNavigationAction:(WKNavigationAction)navigationAction windowFeatures:(WKWindowFeatures*)windowFeatures { NSLog(@"页面弹出窗口"); if(!navigationAction.targetFrame.isMainFrame) { [webViewloadRequest:navigationAction.request]; } return nil;}
