iPhone Landscape FAQ and Solutions

Question

There has been a lot of confusion and a set of corresponding set of questions here on SO how iPhone applications with proper handling for Landscape/Portrait mode autorotatio

Answer 1

I'd like to add to Johannes' answer (using the UINavigationController as MasterViewController).

The disadvantage I have found is that ViewControllers that are newly pushed onto the master VC's navigation stack do not adjust to any prior orientation changes. In short, VCs already on the stack are rotated, modal view controllers presented from them are also rotated, but newly added VCs are not rotated.

I have tried many tricks to fix this before finding one that works. Most only work for pushViewController: with animated set to YES.

To fix the issue entirely, I have subclassed UINagivationController and overriden pushViewController:animated: as follows:

- (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated
{
    // Correctly autoOrient the given view controller
    [self presentModalViewController:viewController animated:NO];
    [self dismissModalViewControllerAnimated:NO];

    // Push it as normal (now in its correct orientation)
    [super pushViewController:viewController animated:animated];
}

Temporarily (and quite invisibly) presenting the view controller allows it to receive its orientation update. It can then be pushed onto the navigation stack in its correct orientation.

Please let me know if this works for you. All updates and improvements are very welcome!

Finally, I highly recommend Johannes' approach to rotation management.

EDIT: Update on popping view controllers from the stack

It seems that all the popViewController-related selectors go crazy when performed with animated:YES. Specifically, the view controller is animated out in the wrong direction. You can use animated:NO and restrict the use of such animations to other UINavigationControllers deeper down in your hierarchy (i.e. the ones that you push onto the root navigation controller's stack).

Any input is greatly appreciated.
