This is a sample XCode project that shows how to create custom split controller (similar to UISplitViewController), which works on both iPhone and iPad. This split view controller works in both landscape and portrait orientations. In addition, it shows you how to create custom tab-bar controller for organizing your controllers, which also works in multiple organizations.
Finally, it comes with a customizer controller that allows users to re-order the tabs based on their likings.
(Note that iPad images are stretched to show that they are horizontal and vertical scrollable)
