Twit to twitter using MGTwitterEngine not Working

Question

I have to integrate Twitter API in iPhone(4.2 and above).For this I am using SA_OAuthTwitterEngine + MGTwitterEngine classes.

I register applicaiton to www.twitter.com/apps and pass Consumer key and Consumer secret to controller my code is this.

if(!_engine){
    _engine = [[SA_OAuthTwitterEngine alloc] initOAuthWithDelegate:self];
    _engine.consumerKey    = KCONSKEY;
    _engine.consumerSecret = KCONSECKEY;  
}

UIViewController *controller = [SA_OAuthTwitterController controllerToEnterCredentialsWithTwitterEngine:_engine delegate:self];

if (controller){
    [self presentModalViewController: controller animated: YES];
}

I have seen this and this example also. In both example we can’t able to twit.. Also, in both example, I ‘m getting error: failed with error: Error Domain=HTTP Code=401 "The operation couldn’t be completed. (HTTP error 401.)” Can Please, any one give me suggestion how to overcome this problem?

Answer 1

[_engine sendUpdate: [NSString stringWithFormat: @"Already Updated. \n%@", [NSDate date]]];

Answer 2

There are changes for API, I guess the MGTwitterEngine is not updated and please do refer the developer site for more information.
