Question

我正在iPhone模拟器中测试一个应用程序，它使用dataWithContentsOfURL: NSData方法实际发出HTTP请求。

我的mac的代理设置受用户名＆amp;保护密码。默认情况下，模拟器不考虑我的Mac中提供的代理设置。我收到了以下回复。有没有办法我们可以编程方式提供代理用户名，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
    }

}
