Question

我正在尝试访问包含xml的页面，我正在尝试解析。我正在使用以下代码，只要我不需要凭据就行。如何向此代码添加凭据？

NSURL *url = [[NSURL alloc] initWithString:URLPath];
NSXMLParser *xmlParser = [[NSXMLParser alloc] initWithContentsOfURL:url];

[xmlParser setDelegate: self];
success = [xmlParser parse];

在我的“URLPath”之上是我的网址字符串。我尝试使用以下url路径格式，但它对我不起作用。 http://username:password@mypage.com/path/to/file.aspx?Function=Update

谢谢！

使用NSURLConnectionDelegates

- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge {
    if ([challenge previousFailureCount] == 0) {
        NSLog(@"received authentication challenge");
        NSURLCredential *newCredential = [NSURLCredential credentialWithUser:@"USER"
                                                                    password:@"PASSWORD"
                                                                 persistence:NSURLCredentialPersistenceForSession];
        NSLog(@"credential created");
        [[challenge sender] useCredential:newCredential forAuthenticationChallenge:challenge];
        NSLog(@"responded to authentication challenge");    
    }
    else {
        NSLog(@"previous authentication failure");
    }
}
