使用Objective-C设置代理用户名和密码 - iPhone

我测试在iPhone模拟器的应用中，它实际上使得使用的NSDatadataWithContentsOfURL:方法的HTTP请求。使用Objective-C设置代理用户名和密码 - iPhone

我的Mac与用户名&密码保护代理设置。默认情况下，模拟器不考虑我的Mac中提供的代理设置。我收到以下回复。有没有一种方法可以以编程方式提供代理用户名和密码，以便模拟器可以读取值并允许请求发生。

-(void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge{ 

    if ([challenge previousFailureCount] == 0) { 
     NSURLCredential *newCredential; 
     newCredential=[NSURLCredential credentialWithUser:@"ABC" 
               password:@"ABC" 
               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 
    }
