This post is from the Activity iPhone Duo UIKit Q&A.
In the iPhone Duo horizontal pose full expanded inner screen, we use UITabBarController (set up using the viewControllers property), and the UITabBar is still horizontal when it should be vertical ? What are the best practices to make it always adaptable in all poses ?
Hello! The tab bar is meant to remain in the horizontal axis in the inner display when in portrait. This is the correct behavior.
On iPhone Duo, the tab bar will not always be in the vertical axis. There are certain heuristics used by the system to determine the axis and location of the tab bar, so please do not assume it will always be in the vertical axis.
