How to force a screen orientation in specific view controllers?

Question

My application is pretty simple: it starts up with a view controller that holds a table view (in grouped view layout) with a few options. When the user taps on one of the op

Answer 1

There does not appear to be a way to do this using the documented methods.

I have filed a bug for this: rdar://6399924

"There is no way to always restrict a UIViewController to one orientation"

You can see it on open radar (along with a link to sample code to reproduce the problem) here: http://openradar.appspot.com/radar?id=697

Answer 2

There is a solution to do that : it's to use a view controller and adding its view to the window. then in that controller you force landscape in the shouldAutorotate... methode. It works fine, but be sure it's necessary for your project to use that, because it's not very smart  to force the user to turn his iPhone. By the way, here is an example code if you need it.

Answer 3

I wasn't able to get this to work the way I wanted. You ought to be able to set a particular orientation for a ViewController, but the NavigationController doesn't seem to always do the right thing.

I ennded up re-designing my screens so that they all work in either orientation. That might be extra work, but it "feels" more natural, anyway.

Like someone on the open radar suggested, a workaround is to disable "back" button while in non-portrait:

- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation{
    // don't let user press "back" button in landscape - otherwise previous view and the rest of the application
    // will also be in landscape which we did not feel like testing yet
    self.navigationController.navigationBarHidden = (UIInterfaceOrientationPortrait != self.interfaceOrientation);
}
