Introduction

In this article we create an empty view application and use a uiviewcontroller class to navigate from one view to another. For changing the style of the navigation bar we use code in the view load method of each view. In this I use two views, FirstViewController and SecondViewController.

Step 1

Open XCode by double-clicking on it.
