UISplitViewController

Remarks

In iOS 8 and later, you can use the UISplitViewController class on all iOS devices, in previous versions of iOS, the class is available only on iPad. UISplitViewController is a container class like UITabViewController, UINavigationController. It separates the main view into two UIViewControllers masterViewController(PrimaryViewController) and detailViewController(SecondaryViewController). we can send an NSArray with two UIViewControllers and Apple recommends UISplitViewController as a rootviewcontroller for your application. To interact between the UIViewControllers I use NSNotificationCenter.
