ブラウザでXML形式で開くSAPビジネスコネクタのURLがあります。SAP BU URLをブラウザに貼り付けると、ポップアップが開き、ユーザーIDとパスワードを尋ねられます。次に、パスワードを入力すると、XML形式のデータが表示されます。iPhoneでXMLファイルを解析する方法を知っていますが、その方法はこのSAPURLでは機能しません。

xcode、Objective Cを使用してiPHoneでユーザーIDとpwdを持つこの種のURLからデータをフェッチするために必要な手順は何ですか？

- (void)applicationDidFinishLaunching:(UIApplication *)application {

self.myURL = [NSURL URLWithString:@"https://connect- test.com....."];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:self.myURL
                                                        cachePolicy:NSURLRequestReloadIgnoringLocalCacheData
                                                    timeoutInterval:60];

[[NSURLConnection alloc] initWithRequest:request delegate:self];

// Configure and show the window
[window addSubview:[navigationController view]];
[window makeKeyAndVisible];
}

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

NSLog(@"received authentication challenge");

NSURLCredential *newCredential;
newCredential=[NSURLCredential credentialWithUser:@"User"
                                          password:@"pwd"
                                        persistence:NSURLCredentialPersistenceForSession];

非同期NSURLConnectionを使用します。この場合、NSURLConnectionDelegateが呼び出され、ユーザー名とパスワードを入力すると、xml応答が返されます。

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

  NSLog(@"received authentication challenge");

  NSURLCredential *newCredential;
  newCredential=[NSURLCredential credentialWithUser:@"root"
             password:@"rootpassword"
             persistence:NSURLCredentialPersistenceForSession];


  NSLog(@"credential created");

  [[challenge sender] useCredential:newCredential forAuthenticationChallenge:challenge];

  NSLog(@"responded to authentication challenge");

}
