解决问题：WKWebView加载不受信任的https

1.描述:因公司域名临时出现问题,所以项目中引用到了IP地址加端口号去请求数据,因而造成在wkwebView中某些网址打不开,查看错误是因为服务器证书无效,实际就是不受信任;  

 

2.解决办法:在plist文件中设置Allow Arbitrary Loads in Web Content 置为 YES,并实现wkwebView下面的代理方法,就可解决  

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