iOS问题记录  WKWebView加载不受信任网页链接

实现WKWebView代理方法,调过证书校验

- (void)webView:(WKWebView *)webView didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge completionHandler:(void (^)(NSURLSessionAuthChallengeDisposition, NSURLCredential * _Nullable))completionHandler {    if ([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust]) {

        if(challenge.previousFailureCount==0) {

            NSURLCredential *credential = [NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust];

            completionHandler(NSURLSessionAuthChallengeUseCredential, credential);

        }else{

            completionHandler(NSURLSessionAuthChallengeUseCredential, nil);

        }

    }else{

        completionHandler(NSURLSessionAuthChallengeUseCredential, nil);

    }

}
