SSL身份驗證在iOS模擬器崩潰

我試圖使用下面的代碼來處理iOS中的SSL連接。它可以在真實設備上正常工作，證書由完全可信的CA頒發。當我嘗試從單元測試運行時，它崩潰了。任何人看到過這種行爲或知道解決方法？SSL身份驗證在iOS模擬器崩潰

- (BOOL) connection:(NSURLConnection *)aConnection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace { 
    NSString *authenticationMethod = protectionSpace.authenticationMethod; 
    NSLog(@"Authentication method: %@", authenticationMethod); 
    return [authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust]; 
} 

- (void) connection:(NSURLConnection *)aConnection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge { 
    NSLog(@"Challenge: %@", challenge); 
    NSURLCredential *proposedCredential = [challenge proposedCredential]; 
    NSLog(@"proposedCredential = %@", proposedCredential); 

    NSURLProtectionSpace *protectionSpace = challenge.protectionSpace; 
    NSLog(@"protectionSpace = %@", protectionSpace); 

    NSString *host = protectionSpace.host; 
    NSLog(@"Trust host: %@", host); 
    id <NSURLAuthenticationChallengeSender> sender = challenge.sender; 
    NSLog(@"sender = %@", sender); 

    if ([protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust]) { 
     if ([trustedHosts containsObject:host]) { 
      SecTrustRef trust = protectionSpace.serverTrust; 
      NSLog(@"trust %p", trust); 
      NSURLCredential *credential = [NSURLCredential credentialForTrust:trust]; 
      NSLog(@"Credential: %@", credential); 


      SecTrustResultType result; 
      OSStatus status = SecTrustEvaluate(trust, &result); 
      NSLog(@"Trust result: %lu", result); 
      NSLog(@"OSStatus = %li", status); 

      NSError *error = [challenge error]; 
      NSLog(@"error = %@", error); 

      [sender useCredential:credential forAuthenticationChallenge:challenge]; 
      NSLog(@"Using credential"); 
     } else { 
      [sender performDefaultHandlingForAuthenticationChallenge:challenge]; 
     } 
    } else { 
     [sender performDefaultHandlingForAuthenticationChallenge:challenge]; 
    } 
}

在AppCode測試用例輸出如下：

目前，我在Xcode 4.3.2上的teamcity CI環境中看到了完全相同的崩潰。試圖找出原因......在我們的情況下，證書不受信任。最煩人的... – Roger 2012-04-02 17:04:12

Darren，這個代碼在Xcode中工作嗎？你使用什麼版本的AppCode？你有沒有嘗試過AppCode 1.5 Release候選版本？（http://eap.jetbrains.com/objc） – 2012-03-09 11:36:17

這個問題似乎通過的iOS 5.1時，Xcode 4.3的一些組合已經解決本身.1和AppCode 1.5.15 EAP。
