Why is WKWebView not opening links with target="_blank"?

My solution is to cancel the navigation and load the request with loadRequest: again. This will be come the similar behavior like UIWebView which always open new window in the current frame.

Implement the WKUIDelegate delegate and set it to _webview.uiDelegate. Then implement:

- (WKWebView *)webView:(WKWebView *)webView createWebViewWithConfiguration:(WKWebViewConfiguration *)configuration forNavigationAction:(WKNavigationAction *)navigationAction windowFeatures:(WKWindowFeatures *)windowFeatures{  if (!navigationAction.targetFrame.isMainFrame) {    [webView loadRequest:navigationAction.request];  }  return nil;}

The answer from @Cloud Xu is the correct answer. Just for reference, here it is in Swift:

// this handles target=_blank links by opening them in the same viewfunc webView(webView: WKWebView!, createWebViewWithConfiguration configuration: WKWebViewConfiguration!, forNavigationAction navigationAction: WKNavigationAction!, windowFeatures: WKWindowFeatures!) -> WKWebView! {    if navigationAction.targetFrame == nil {        webView.loadRequest(navigationAction.request)    }    return nil}

To use latest version of Swift 4.2+

import WebKit

Extend your class with WKUIDelegate

Set delegate for webview

self.webView.uiDelegate = self

Implement protocol method

func webView(_ webView: WKWebView, createWebViewWith configuration: WKWebViewConfiguration, for navigationAction: WKNavigationAction, windowFeatures: WKWindowFeatures) -> WKWebView? {    if navigationAction.targetFrame == nil {        webView.load(navigationAction.request)    }    return nil}
