ios - 在登录成功时运行函数 MGTwitterEngine ala FBConnect

Question

我是第一次使用该引擎，对 iOS 开发还很陌生。我很好奇是否有办法在我登录成功后调用函数？我似乎无法让它按照 FBConnect 在初始登录功能后调用 fbDidLogin 的方式工作。我声明了 MGTwitterEngineDelegate 并尝试在登录后使用以下代码:

//TWITTER LOGIN FUNCTION/////////////////////
-(void)twitLogin{
    NSLog(@"Inside of twitLogin...");
    if(![_engine isAuthorized]){  
        UIViewController *controller = [SA_OAuthTwitterController controllerToEnterCredentialsWithTwitterEngine:_engine delegate:self];  

        if (controller){  
            [self presentModalViewController: controller animated: YES]; 
            NSLog(@"Inside of Twitter login UIWebView.");
        }  else {
            NSLog(@"ONCE WE'RE LOGGED IN, LETS SEND THE TWEET!");
            NSString *tweet = [[NSString alloc] initWithFormat:@"My Tweet!"];
            [_engine sendUpdate:tweet];
            NSLog(@"You just tweeted: %@",tweet);
        }

    }  else {
        NSString *twitterToken=[[NSUserDefaults standardUserDefaults] objectForKey:@"authData"];
        NSLog(@"Twitter is authorized?: %@",twitterToken);
        //Twitter Integration Code Goes Here
        NSString *tweet = [[NSString alloc] initWithFormat:@"My Tweet!"];
        [_engine sendUpdate:tweet];
        NSLog(@"You just tweeted: %@",tweet);
    }

}

感谢任何帮助。非常感谢!

我之前发布的解决方案 %100 不起作用，原来我没有在我的 Controller 中为登录成功设置正确的委托(delegate):

#pragma mark SA_OAuthTwitterController Delegate

- (void) OAuthTwitterController: (SA_OAuthTwitterController *) controller authenticatedWithUsername: (NSString *) username {

    NSLog(@"Authenticated with user %@", username);

    tweets = [[NSMutableArray alloc] init];
    [self updateStream:nil];
}

希望对大家有帮助!
