TabScrollPageViewController

Overview

The tab bar at the top of the screen moves synchronously with page scrolling.

When you press a tab, it will transition to the page you pressed.

It would be great if you would like to use UIPageViewController to build applications synchronized with the tab bar at the top of the screen.

Cocoapods

CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:

$ gem install cocoapods

To integrate TabPageScrollViewController into your Xcode project using CocoaPods, specify it in your Podfile:

vi ./Podfile

target 'MyApp' do
  pod 'TabPageScrollViewController'
end

Use it
