UISplitViewController display master view above detail in portrait orientation

I have a UISplitViewController embedded in a UINavigationController with a UINavigationItem button to toggle the display of the master view in portrait orientation. I want to show the master view above the detail view when the view first loads in portrait orientation.

Any similar examples I have found show the master and detail views splitting the screen in portrait orientation, but I need the detail view to be full screen in portrait with the master view covering the detail view when the UISplitViewController first loads (as if the master view has been swiped out from the left). Does anyone know how to do that?

Edit: It's not a duplicate. Answer discovered in the comments. The solution is to use preferredDisplayMode on UISplitViewController and setting it to UISplitViewControllerDisplayModePrimaryOverlay

Left the original answer for context to the comments and posterity.


Original Answer

This is a duplicate of this: UISplitViewController in portrait on iPhone shows detail VC instead of master

For reference, the solution in that case was to have the view controller that implements UISplitViewControllerDelegate use the following code:

- (BOOL)splitViewController:(UISplitViewController *)splitViewController
collapseSecondaryViewController:(UIViewController *)secondaryViewController
  ontoPrimaryViewController:(UIViewController *)primaryViewController {

    if ([secondaryViewController isKindOfClass:[UINavigationController class]]
        && [[(UINavigationController *)secondaryViewController topViewController] isKindOfClass:[DetailViewController class]]
        && ([(DetailViewController *)[(UINavigationController *)secondaryViewController topViewController] detailItem] == nil)) {

        // Return YES to indicate that we have handled the collapse by doing nothing; the secondary controller will be discarded.
        return YES;

    } else {

        return NO;

    }
}
