## Example

To run the example project, clone the repo, and run `pod install` from the Example directory first.

```swift

class ViewController: UIViewController, UIScrollViewDelegate {

    let scrollview: UIScrollView = {

        let sv = UIScrollView()

        sv.minimumZoomScale = 0.5

        sv.maximumZoomScale = 20

        sv.contentSize = CGSize(width: UIScreen.main.bounds.width * 2, height: UIScreen.main.bounds.height * 2)

        sv.frame = UIScreen.main.bounds

        return sv

    }()

    let control: UIImageView = {

       let v = UIImageView(image: UIImage(named: "avatar"))

        v.frame = CGRect(x: 0,

                         y: (UIScreen.main.bounds.height - UIScreen.main.bounds.width)/2,

                         width: UIScreen.main.bounds.width,

                         height: UIScreen.main.bounds.width)

        return v

    }()

    let svt = ScrollViewThumbnailView(frame: CGRect(x: 0, y: UIScreen.main.bounds.height - 200, width: 200, height: 200))

    

    override func viewDidLoad() {

        super.viewDidLoad()

        automaticallyAdjustsScrollViewInsets = false

        scrollview.delegate = self

        

        view.addSubview(scrollview)

        view.addSubview(svt)

        scrollview.addSubview(control)

        // Just bind scrollview for  ScrollViewThumbnailView here.

        svt.bindScrollView(scrollview)

    }

    override func didReceiveMemoryWarning() {

        super.didReceiveMemoryWarning()
