I'm testing an application in iPhone simulator where it actually makes an HTTP request using dataWithContentsOfURL: method of NSData.

My mac has proxy settings protected with username & password. By default the simulator is not considering the proxy settings provided开发者_如何学C in my Mac. I'm getting the following response. Is there a way where we can programmatically provide the proxy username, password so that the simulator can read the values and allow the request to take place.

This is typically caused by an incorrect username and/or password, but could also be caused by network problems.

-(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
    }
