1. You can use CocoaPods

pod 'BabuPagerViewController'

2. Or you can just copy 'BabuPagerViewController.swift' to your project.

How to use

1. Make the Subclass of BabuPagerViewController

class ViewController: BabuPagerViewController, BabuPagerViewControllerDataSource, BabuPagerViewControllerDelegate {
  var titles = ["red", "blue", "green", "yellow", "cyan"]

  override func viewDidLoad() {
    super.viewDidLoad()

    self.dataSource = self
    self.delegate = self

  }

  ...

  // MARK: - BabuPagerViewControllerDataSource
  func numberOfPagerItem() -> Int {
    return self.titles.count
  }

  func titleForTab(index: Int) -> String {
    return self.titles[index]
  }

  func pagerItemViewController(index: Int) -> UIViewController {
    var viewController = self.storyboard!.instantiateViewControllerWithIdentifier("pageItem") as! UIViewController
    viewController.title = self.titles[index]
    return viewController
  }

  // MARK: - BabuPagerViewControllerDelegate
  func pagerViewController(pagerViewController: BabuPagerViewController, willTransitionToViewController: AnyObject) {
    ...
  }

  func pagerViewController(pagerViewController: BabuPagerViewController, didFinishAnimating finished: Bool) {
    // You can get the current index.
    let pageIndex = pagerViewController.currentIndex()
    ...
  }
}

2. Connect to headerView on the Storyboard if you need to

3. Connect to tabView on the Storyboard if you need to

4. You can select the position of tabView between top and bottom.
