wkwebview 重定向處理新開窗口問題

方法一：網頁里面target的值置為空- (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 中有兩個屬性：sourceFrame和targetFrame，分別代表這個action的出處和目標。類型是 WKFrameInfo 。WKFrameInfo有一個 mainFrame 的屬性，正是這個屬性標記着這個frame是在主frame里還是新開一個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 自帶的WKUIDelegate代理方法- (WKWebView)webView:(WKWebView)webView createWebViewWithConfiguration:(WKWebViewConfiguration)configuration forNavigationAction:(WKNavigationAction)navigationAction windowFeatures:(WKWindowFeatures*)windowFeatures {    NSLog(@"頁面彈出窗口");    if(!navigationAction.targetFrame.isMainFrame) {        [webViewloadRequest:navigationAction.request];    }    return nil;}
