Set orientation to Portrait in one view when the navigation controller is portrait

If my application is in开发者_C百科 the Landscape position and then they press a button to load the info view, how can I set the info view to only support the portrait position, and therefore change the orientation to portrait when the view is loaded?

Maybe something like this:

[application setStatusBarOrientation:UIInterfaceOrientationPortrait animated:NO];

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    return (UIInterfaceOrientationPortrait == interfaceOrientation )
}
