Getting Started

import EVTopTabBar

Implement the EVTabBar protocol and conform to it (The example project has a detailed implementation). In order to conform to the protocol declare:

var pageController = UIPageViewController(transitionStyle: .Scroll, navigationOrientation: .Horizontal, options: nil)
//need to instantiate the topTabBar itself, later we will implement the delegate method
//enum .two, .three, .four correspond to the number of tabs you wish to display
var topTabBar: EVPageViewTopTabBar = EVPageViewTopTabBar(for: .four)
//array of view controllers that will be controlled by the page view controller
var subviewControllers: [UIViewController] = []
//image from the sample project can use any UIImage you want, this shadow is what is displayed under the tab bar.
var shadowView = UIImageView(image: UIImage(imageLiteral: "filter-background-image"))

Now in your view controller implement the EVPageViewTopTabBarDelegate method willSelectViewControllerAtIndex This method allows for view controllers to switch and gives a space to perform any other actions.

extension ViewController: EVPageViewTopTabBarDelegate {
    //delegate method
    func willSelectViewControllerAtIndex(index: Int, direction: UIPageViewControllerNavigationDirection) {
        //required line that changes the displayed view controller
        pageController.setViewControllers([self.subviewControllers[index]], direction: direction, animated: true, completion: nil)
        //add whatever code you wish to occur on the transition!
    }
}

Next will want to call the setupPageView() and setupConstraints() methods in order to setup the page layout. You can override both of these methods to create a more custom application.

Lastly you will want to setup the topTabBar you previously declared

//attributes of the topTabBar you can set
topTabBar.fontColors = (selectedColor: UIColor.grayColor(), unselectedColor: UIColor.lightGrayColor())
topTabBar.rightButtonText = "Events"
topTabBar.leftButtonText = "Contacts"
topTabBar.labelFont = UIFont(name: ".SFUIText-Regular", size: 11)!
topTabBar.indicatorViewColor = UIColor.blueColor()
topTabBar.backgroundColor = UIColor.whiteColor()
//ensure you set the topTabBar's delegate
topTabBar.delegate = self
//add view controllers you wish to display
let firstVC = FirstViewController(nibName:"FirstViewController", bundle: nil)
let secondVC = SecondViewController(nibName:"SecondViewController", bundle: nil)
subviewControllers = [firstVC, secondVC]
setupPageView()
setupConstraints()

Project description
