Paginated UIScrollView, a simple UIPageViewController alternative written in Swift.

PaginatedScrollView

Simple paginated UIScrollView subclass that supports UIViewControllers as pages. It handles rotation pretty well, too.

Usage

import UIKit

class RootController: UIViewController {
    var pages: [UIViewController] {
        let firstController = UIViewController()
        firstController.view.backgroundColor = UIColor.redColor()

        let secondController = UIViewController()
        secondController.view.backgroundColor = UIColor.greenColor()

        let thirdController = UIViewController()
        thirdController.view.backgroundColor = UIColor.purpleColor()

        return [firstController, secondController, thirdController]
    }

    lazy var scrollView: PaginatedScrollView = {
        let view = PaginatedScrollView(frame: view.frame, parentController: self, initialPage: 0)
        view.viewDataSource = self

        return view
    }()

    override func viewDidLoad() {
        super.viewDidLoad()

        view.addSubview(scrollView)
    }

    override func viewWillLayoutSubviews() {
        super.viewWillLayoutSubviews()

        scrollView.configure()
    }
}

extension RootController: PaginatedScrollViewDataSource {
    func numberOfPagesInPaginatedScrollView(paginatedScrollView: PaginatedScrollView) -> Int {
        return pages.count
    }

    func paginatedScrollView(paginatedScrollView: PaginatedScrollView, controllerAtIndex index: Int) -> UIViewController {
        return pages[index]
    }
}

PaginatedScrollViewDelegate

UIPageViewController is kind of lame when it comes to knowing exactly when you have switched to the next page or went back to the previous one. That's the main reason why PaginatedScrollView exists.

protocol PaginatedScrollViewDelegate: class {
    func paginatedScrollView(paginatedScrollView: PaginatedScrollView, didMoveToIndex index: Int)
    func paginatedScrollView(paginatedScrollView: PaginatedScrollView, didMoveFromIndex index: Int)
}
