試過幾年前的若干種方式全部無用，Info.plist添加白名單、添加NSURLRequest分類都會(huì)報(bào)錯(cuò):

"The certificate for this server is invalid. You might be connecting to a server that is pretending to be “xxxx” which could put your confidential information at risk.

正確方式：添加WKNavigationDelegate方法

- (void)webView:(WKWebView *)webView didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge completionHandler:(void (^)(NSURLSessionAuthChallengeDisposition disposition, NSURLCredential * _Nullable credential))completionHandler {
    if ([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust]) {
        NSURLCredential *credential = [[NSURLCredential alloc]initWithTrust:challenge.protectionSpace.serverTrust];
        completionHandler(NSURLSessionAuthChallengeUseCredential,credential);
    }
}

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