创建NSURLConnection的认证质询的SecCertificateRef(Creating

我从一台服务器我的应用程序试图连接到接收认证质询，所以我已经实现了connection:didReceiveAuthenticationChallenge:方法。我需要发送一个SecCertificateRef和SecIdentityRef 。身份工作，但需要发送的该证书NSArray ，我无法弄清楚如何将转换CFArrayRef到NSArray 。

这是我创造的身份和证书的方法：

// Returns an array containing the certificate
- (CFArrayRef)getCertificate {
  SecCertificateRef certificate = nil;
  NSString *thePath = [[NSBundle mainBundle] pathForResource:@"CertificateName" ofType:@"p12"];
  NSData *PKCS12Data = [[NSData alloc] initWithContentsOfFile:thePath];
  CFDataRef inPKCS12Data = (__bridge CFDataRef)PKCS12Data;
  certificate = SecCertificateCreateWithData(nil, inPKCS12Data);
  SecCertificateRef certs[1] = { certificate };
  CFArrayRef array = CFArrayCreate(NULL, (const void **) certs, 1, NULL);

  SecPolicyRef myPolicy   = SecPolicyCreateBasicX509();
  SecTrustRef myTrust;

  OSStatus status = SecTrustCreateWithCertificates(array, myPolicy, &myTrust);
  if (status == noErr) {
    NSLog(@"No Err creating certificate");
  } else {
    NSLog(@"Possible Err Creating certificate");
  }
  return array;
}

// Returns the identity
- (SecIdentityRef)getClientCertificate {
  SecIdentityRef identityApp = nil;
  NSString *thePath = [[NSBundle mainBundle] pathForResource:@"CertificateName" ofType:@"p12"];
  NSData *PKCS12Data = [[NSData alloc] initWithContentsOfFile:thePath];
  CFDataRef inPKCS12Data = (__bridge CFDataRef)PKCS12Data;
  CFStringRef password = CFSTR("password");
  const void *keys[] = { kSecImportExportPassphrase };//kSecImportExportPassphrase };
  const void *values[] = { password };
  CFDictionaryRef options = CFDictionaryCreate(NULL, keys, values, 1, NULL, NULL);
  CFArrayRef items = CFArrayCreate(NULL, 0, 0, NULL);
  OSStatus securityError = SecPKCS12Import(inPKCS12Data, options, &items);
  CFRelease(options);
  CFRelease(password);
  if (securityError == errSecSuccess) {
    NSLog(@"Success opening p12 certificate. Items: %ld", CFArrayGetCount(items));
    CFDictionaryRef identityDict = CFArrayGetValueAtIndex(items, 0);
    identityApp = (SecIdentityRef)CFDictionaryGetValue(identityDict, kSecImportItemIdentity);
  } else {
    NSLog(@"Error opening Certificate.");
  }
  return identityApp;
}

然后在connection:didReceiveAuthenticationChallenge:我有：

- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge {
  if ([challenge previousFailureCount] == 0) {
    SecIdentityRef identity = [self getClientCertificate];  // Go get a SecIdentityRef
    CFArrayRef certs = [self getCertificate]; // Get an array of certificates

    // Convert the CFArrayRef to a NSArray
    NSArray *myArray = (__bridge NSArray *)certs;

    // Create the NSURLCredential
    NSURLCredential *newCredential = [NSURLCredential credentialWithIdentity:identity certificates:certs persistence:NSURLCredentialPersistenceNone];

    // Send
    [challenge.sender useCredential:newCredential forAuthenticationChallenge:challenge];
  } else {
    // Failed
    [[challenge sender] cancelAuthenticationChallenge:challenge];
  }
}

当该应用程序崩溃NSURLCredential创建。经进一步检查，我的结论是，当我转换CFArrayRef到NSArray ，该数据SecCertificateRef丢失，并且阵列包含null导致飞机坠毁。

我怎么可能把一个SecCertificateRef在NSArray ？我错过了一步，难道只是我做错了？

我终于找到了答案。我本来是要使用SecIdentityCopyCertificate(identity, &certificateRef); 代替SecCertificateCreateWithData(nil, inPKCS12Data); 创建我的证书。
