title: Strange Problem with MGTwitterEngine for ipad
body: <p>I am stuck with the strange problem of MGTwitterEngine for iPad because when I use it for iPhone it works perfectly but when I use it for iPad then in method below(delegate method) I am getting username as null but in iPhone it was giving correct(eg.soha00)</p>
  
  <p>Code for calling MGTwitterEngine:-</p>
  
  <pre><code>-(IBAction)loginWithTwitterButtonClicked:(UIButton *)sender
    {
        _engine = [[SA_OAuthTwitterEngine alloc] initOAuthWithDelegate:self];
        _engine.consumerKey = @"PzkZj9g57ah2bcB58mD4Q";
        _engine.consumerSecret = @"OvogWpara8xybjMUDGcLklOeZSF12xnYHLE37rel2g";
  
        UIViewController *controller = [SA_OAuthTwitterController controllerToEnterCredentialsWithTwitterEngine: _engine delegate: self];
  
        if (controller) 
        {
            [self presentModalViewController: controller animated: YES];
        }
  
    }
  </code></pre>
  
  <p>The below method is the delegate method that gets called when authorize button is clicked.</p>
  
  <pre><code>- (void) OAuthTwitterController: (SA_OAuthTwitterController *) controller authenticatedWithUsername: (NSString *) username {
  
      NSLog(@"Authenticated with user %@", username);
  }
  </code></pre>
  
  <p><strong>In iPhone it is showing username properly but on iPad it is returning nil.</strong></p>
  
  <p>Please suggest me what might be the problem or how could I sort this issue.
  Please help me.
  Thanks in advance!</p>
