How to create Tab Bar Layout in an iOS App?

You can see how one can use tab bar layout in their application.

A tab bar appears at the bottom of an app screen and provides the ability to quickly switch between different sections of an app. Tab bars are translucent, may have a background tint, maintain the same height in all screen orientations, and are hidden when a keyboard is displayed. A tab bar may contain any number of tabs, but the number of visible tabs varies based on the device size and orientation.
