iPhone模拟器上的代理授权

Question

有这样的问题，希望你能帮助我..找不到任何地方。下面是我使用的代码：

NSURL *serverURL = [NSURL URLWithString:@"http://someServer.com/Login"]; 
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:serverURL]; 
[request addValue:@"text/plain" forHTTPHeaderField:@"ACCEPT"]; 
[request setHTTPMethod:@"POST"]; 

[request setCachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData]; 

NSData *data = [encodedString dataUsingEncoding:NSUTF8StringEncoding]; 
[request setHTTPBody:data]; 

URLLoader *loader = [URLLoader loaderWithRequest:request]; 

当我想从电脑都可以在浏览器中查看在服务器http://someServer.com/Login。

当我尝试从iPhone模拟器上的safary访问相同的服务器 - 授权后出现授权窗口一切正常。

但是，当我在iPhone模拟器上以程序方式执行此请求时，我发布了代码示例。出现下一个错误：

The following error was encountered: 
Cache Access Denied. 

Sorry, you are not currently allowed to request: 
    http://someserver.com/Login 
from this cache until you have authenticated yourself. 

我该如何解决这个问题？感谢名单！

似乎您在拨打电话时需要发送身份验证凭据。 尝试使用NSURLConnection类拨打电话，设置委托，并实现以下方法

-(void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge{ 
    if ([challenge previousFailureCount] == 0) { 
     NSURLCredential *newCredential; 
     newCredential=[NSURLCredential credentialWithUser:@"ABC" 
               password:@"XYZ" 
               persistence:NSURLCredentialPersistenceNone]; 
     [[challenge sender] useCredential:newCredential 
       forAuthenticationChallenge:challenge]; 

    } else { 

     [[challenge sender] cancelAuthenticationChallenge:challenge]; 
     // inform the user that the user name and password 
     // in the preferences are incorrect 
    } 

}
