If you scroll down a bit at this Apple Developer Page you'll find the section "Creating an Alternate Landscape Interface". The basic approach described there is to present a different NIB file as a modal view when orientation changes. I am using the Storyboard feature, so I don't have NIBs. How do I load a different "scene" in that case?
Besides that, I am using a Tab Bar controller, I don't want to show a modal view. I just want to replace the current portrait view with a landscape view designed with interface builder and keep my tab bar. What would be the Storyboard way to achieve the task "Creating an Alternate Landscape Interface"? Thank you.
When you add a view controller to the storyboard it comes with a view. Call that the container view. Add two views to the container view: a portrait view and a landscape view. Set the dimension of the portrait view and the landscape view appropriately using the size inspector. Add buttons, more views, labels or whatever to the portrait and landscape views as needed for your application. Then when the orientation changes hide one view and show the other.
