4. ImageContentViewController.swift

5. ImagePageViewController.swift

add following code to your viewcontroller

``` swift

  //Add your local images

  imageViewController.images = ["image1","image2"]

  

  let navigationController = UINavigationController.init(rootViewController: imageViewController)

  

  self.presentViewController(navigationController, animated: true) {

var images = [AnyObject]()

//UIPageControl displayed in botton

@IBOutlet weak var pageControl: UIPageControl!

func imageViewController(imageViewController: ImageViewController,

                             imagePageViewController: ImagePageViewController,

                                 didUpdatePageCount count: Int)

//Called when the current index is updated.

func imageViewController(imageViewController: ImageViewController,

                             imagePageViewController: ImagePageViewController,

                                 didUpdatePageIndex index: Int)

```

//Scrolls to the next view controller.

func scrollToNextViewController() 

```
