Different view of the switch

Because it is a beginner so I do not know how this question should be to ask questions, so I wrote a different view of the switching
I built the project in view architecture I want to achieve is a common point of view interface a button when I entered the second interface and the second interface is loaded UITabBarItem this control. UITabBarItem because the controls in the Tab bar template using inherited Inherits from
UIBarItem: NSObject. So do not go under normal circumstances loaded. I do not know how to achieve switching between two different view please advise! Thank you
