Ios NSURLConnection使用由自定义CA签名的证书与具有SSL的CocoaHTTPServer连接失败

我有一个小应用程序，里面有CocoaHttpServer。我只想为环回呼叫启用它，并且我只想能够从我的应用程序拨打这些电话。别问为什么——我需要它

self.httpServer = [[HTTPServer alloc] init];
self.httpServer.port = HTTP_SERVER_PORT;
self.httpServer.interface = @"loopback";
self.httpServer.connectionClass = [HTTPSolFSConnection class];

NSError *error;
if([self.httpServer start:&error]) {
    DDLogInfo(@"Started HTTP Server on port %hu", [self.httpServer listeningPort]);
}
else {
    DDLogError(@"Error starting HTTP Server: %@", error);
}

服务器使用自定义HTTPConnection类，该类在isSecureServer方法中返回YES，并使用使用自定义CA签名的证书

- (BOOL)isSecureServer {
    return YES;
}

- (NSArray *)sslIdentityAndCertificates {
    NSArray *result = nil;

    NSData *serverCertificateData = [[NSData alloc] initWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"server" ofType:@"p12"]];

    const void *keys[] =   { kSecImportExportPassphrase };
    const void *values[] = { CFSTR("friday_internet") };
    CFDictionaryRef options = CFDictionaryCreate(NULL, keys, values, 1, NULL, NULL);

    CFArrayRef items = NULL;
    OSStatus securityError = SecPKCS12Import((__bridge CFDataRef) serverCertificateData, options, &items);

    if (options) {
        CFRelease(options);
    }

    if (securityError == errSecSuccess) {
        CFDictionaryRef myIdentityAndTrust = CFArrayGetValueAtIndex(items, 0);
        SecIdentityRef identity = (SecIdentityRef) CFDictionaryGetValue(myIdentityAndTrust, kSecImportItemIdentity);

        SecCertificateRef serverCertificate = NULL;
        SecIdentityCopyCertificate(identity, &serverCertificate);

        NSData *caCertificateData = [[NSData alloc] initWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"ca" ofType:@"der"]];
        SecCertificateRef caCertificate = SecCertificateCreateWithData(NULL, (__bridge CFDataRef) caCertificateData);
        NSArray *anchorCertificates = @[ (__bridge id) serverCertificate, (__bridge id) caCertificate ];

        SecTrustResultType trustResult;
        SecTrustRef trust = (SecTrustRef) CFDictionaryGetValue(myIdentityAndTrust, kSecImportItemTrust);
        SecTrustSetAnchorCertificates(trust, (__bridge CFArrayRef) anchorCertificates);
        SecTrustSetAnchorCertificatesOnly(trust, false);

        SecTrustEvaluate(trust, &trustResult);
        NSLog(@"SecTrustResultType: %d", trustResult);

        result = @[ (__bridge id) identity, (__bridge id) caCertificate, (__bridge id) serverCertificate ];

        if (serverCertificate) {
            CFRelease(serverCertificate);
        }
    }

    if (items) {
        CFRelease(items);
    }

    return result;
}

每次我创建到服务器的NSURLConnection时，它都会记录SectursResultType:4并失败，错误为：

我读了很多关于StackOverflow的文章和问题，但都无济于事：

有两种“黑客”可以解决这个问题：

我可以实现connection:willSendRequestForAuthenticationChallenge:NSURLConnectionLegate方法

我可以实现自定义NSURL协议

通过电子邮件将CA的证书发送到设备并手动信任它

---

问题是，我在我的应用程序中使用了一个第三方库，它与我的服务器进行通信。它不使用基础框架，所以首先两种方法不起作用。有没有一种方法可以通过编程而不是手动发送证书？

您解决过这个问题吗？
