You can't use UISplitViewController on iPhone, it's iPad-only feature.

The UISplitViewController class is a container view controller that manages the presentation of two side-by-side view controllers. You use this class to implement a master-detail interface, in which the left-side view controller presents a list of items and the right-side presents details of the selected item. Split view controllers are for use exclusively on iPad devices. Attempting to create one on other devices results in an exception.
