Alright , there exist library called PagingMenuController
on github helps you to go throw this and build what you want by this link : https://github.com/kitasuke/PagingMenuController. Or you may use the library you have found for that. as i said just download their project and see how it works, Then import it into your project.
You may download their library which is written by Swift and support Swift 2 and IOS8+
.
Note: Try follow user experience and what i mean here IOS is different than android, i suggest you build UITabbar
instead of this. as example : WhatsApp
on android uses view pager but on iPhone uses UITabbar
