## Introduction

DraggableModalTransition enables dragging interaction and animation of scrollView in a similar way to Facebook Messenger app.  

Inspired by [zoonooz/ZFDragableModalTransition](https://github.com/zoonooz/ZFDragableModalTransition). Key difference is you can **continue dragging scrollView after you have finished scrolling to top of it** (See example below).

## Example



Example project is available at `Example/DraggableModalTransition.xcodeproj`.

## Usage

Set an instance of `DraggableModalTransition` to `transitioningDelegate` of viewController you want to present.  

Note that you have to keep an instance of `DraggableModalTransition` even after view is presented.

```swift

func presentModalView() {

    let controller = ModalViewController()

    let navigationController = UINavigationController(rootViewController: controller)

 

    modalTransition = DraggableModalTransition(with: controller)

    navigationController.transitioningDelegate = modalTransition

    controller.modalViewControllerDelegate = modalTransition

    present(navigationController, animated: true, completion: nil)

}

```

For now you also need to call `modalViewDidScroll` in your `scrollViewDidScroll`.

```swift

class ModalViewController {

    weak var modalViewControllerDelegate: ModalViewControllerDelegate?

    ...

    func scrollViewDidScroll(_ scrollView: UIScrollView) {

        modalViewControllerDelegate?.modalViewDidScroll(scrollView)

    }

} 

```

See example project for more details.
