在报告不符合测试版的情况下，努力更新iOS5的应用程序。该问题被追溯到我们的自定义SSL证书验证不再有效的事实。

在didReceiveAuthenticationChallenge部分中，我们获取了根证书并调用了SecTrustEvaluate。这适用于iOS4。

protectionSpace = [challenge protectionSpace];
    trust = [protectionSpace serverTrust];

    err = SecTrustEvaluate(trust, &trustResult);

    trusted = (err == noErr) && ((trustResult == kSecTrustResultProceed) || (trustResult == kSecTrustResultUnspecified));

    if (!trusted) { 
        err = SecTrustSetAnchorCertificates(trust, (CFArrayRef)[EagleAccessAppDelegate getDelegate].rootCertificates);

        if (err == noErr) {
            err = SecTrustEvaluate(trust, &trustResult);
        }

        trusted = (err == noErr) && ((trustResult == kSecTrustResultProceed) || (trustResult == kSecTrustResultUnspecified));
    }

    if (trusted) { 
        NSURLCredential *cred = [NSURLCredential credentialForTrust:trust];
        [[challenge sender] useCredential:cred forAuthenticationChallenge:challenge];
    } else { 
        [[challenge sender] cancelAuthenticationChallenge:challenge];
    }

证书以DER格式存储为应用程序附带的资源。

// Load Certificates. 
NSString *devFilePath = [[NSBundle mainBundle] pathForResource:@"ipms-dev-ca.der" ofType:@"crt"];  
NSData *devRootCertificate = [[[NSData alloc] initWithContentsOfFile:devFilePath] autorelease];
SecCertificateRef devRoot = SecCertificateCreateWithData(NULL, (CFDataRef) devRootCertificate);

NSString *prodFilePath = [[NSBundle mainBundle] pathForResource:@"ipms-prod-ca.der" ofType:@"crt"];  
NSData *prodRootCertificate = [[[NSData alloc] initWithContentsOfFile:prodFilePath] autorelease];
SecCertificateRef prodRoot = SecCertificateCreateWithData(NULL, (CFDataRef) prodRootCertificate);

self.rootCertificates = [[NSArray alloc] initWithObjects:(id)devRoot, (id)prodRoot, nil];

我们基本上拥有自己的CA证书，我们用它来为我们的应用程序连接的服务器颁发证书。

我可以使用AdvancedURLConnections示例应用程序重新创建它。

问题是证书是MD5签名。 iOS5不再支持这些签名。

SecTrustEvaluate在iOS 5上返回kSecTrustResultRecoverableTrustFailure
