UISplitViewController in portrait: how to hide master popover programmatically?

Question

In my UISplitViewController the master controller is a UINavigationController. When in portrait mode I would like to keep the navigation controller

Answer 1

The IOS 6.0 SplitView template has this built in. The detail view tracks the orientation and the MasterViewController popover.

Simply set the detailItem and the popover disappears if appropriate. There is even a check if you are using the same detaiItem so no page setup and refresh work gets done.

self.detailViewController.detailItem = self.detailViewController.detailItem;
