Hi

I am using MGTwitterEngine in Iphone application

But I am getting error in log of function
- (void)requestFailed:(NSString *)connectionIdentifier withError:
(NSError *)error
{
    NSLog(@"Twitter Request failed for connectionIdentifier = %@,
error = %@ (%@)",
          connectionIdentifier,
          [error localizedDescription],
          [error userInfo]);
}

Error Log

Twitter Request failed for connectionIdentifier =
8E192CD3-35E5-46C8-86E9-1EADEE38B6E8, error = The operation couldn’t
be completed. (HTTP error 401.) ({
    body = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<hash>\n
<request>/oauth/access_token</request>\n  <error>Client application is
not permitted to use xAuth.</error>\n</hash>\n";
    response = "<NSHTTPURLResponse: 0x603b6a0>";
})



following code in controller class
-(IBAction)twitterBtnAct:(id)sender{
    // Put your Twitter username and password here:
    NSString *username = @"myusername";
    NSString *password = @"mypassword";

    NSString *consumerKey = @"b2jD5AXJewSNfmCBfzvlw";
    NSString *consumerSecret =
@"ceqEECJalqtVUnxl8sNQxrh5dXGUvo9cg4HxKNn6g";

    // Most API calls require a name and password to be set...
    if (! username || ! password || !consumerKey || !consumerSecret) {
        NSLog(@"You forgot to specify your username/password/key/
secret in AppController.m, things might not work!");
                NSLog(@"And if things are mysteriously working without the 
username/
password, it's because NSURLConnection is using a session cookie from
another connection.");
    }

    // Create a TwitterEngine and set our login details.
    twitterEngine = [[MGTwitterEngine alloc] initWithDelegate:self];
    [twitterEngine setUsesSecureConnection:NO];
    [twitterEngine setConsumerKey:consumerKey secret:consumerSecret];
    // This has been undepreciated for the purposes of dealing with
Lists.
    // At present the list API calls require you to specify a user
that owns the list.
    [twitterEngine setUsername:username];

    [twitterEngine getXAuthAccessTokenForUsername:username
password:password];
}
