restricting autorotation on certain views

hi, in my app i toggled the portrait, landscape left/right buttons in the project summary. my app contains a view controller as a root view controller, and a table view controller which the user can navigate to when clicking a button in the view controller. i want to let the user to be able to rotate the screen in the table view but not in the view controller. how can i restrict rotation to a view controller?

 

HI, i read the ios 6 part since shouldAutorotateToInterfaceOrientation: has been deprecated from ios 6 and onwards. however i didn't find an answer to my problem. i toggled the portrait and landscape left from the project summary and in the view controller (root controller) i added the following:

Code:

- (UIInterfaceOrientation) preferredInterfaceOrientationForPresentation
{
    return UIInterfaceOrientationMaskPortrait;
}

when running the app, it opens in portrait but when i rotate the device, the view rotates to landscape left. thus the restriction to one orientation from the ones supported failed. i tried using ShouldAutorotate to restrict it to one orientation but it seems it's not even entering the method (i used nslog to detect that).any hint? i want it to open only in portrait no matter how i rotate the device.
