Manual

Download the project, just drag and drop classes under BottomPopupController file to your project.

After install, simply make your view controller subclass of BottomPopupViewController.

For navigation controllers, it works exactly in same way, make your navigation controller subclass of BottomPopupNavigationController.

Congratulations, your view controller is ready to show 🎉

Then you can present your controller with native presentViewController:animated:completion: method, bottom popup controller will handle rest.

Bottom popup comes with couple of customizable properties. Since your view controller subclass of BottomPopupViewController now, you can override following properties in your view controller to change behaviour;

• popupShouldDismissInteractivelty: Bool

  Determines the popup should dismiss whether interactively or not. If it is set to yes, user can dismiss popup with pulling down it down. Default is YES

• popupHeight: BOOL

  Height value. Default is 377 pt. For example you can return UIScreen.main.bounds.size.height to give it full screen height.

  Corner radius of popup. Default is 10pt

• popupPresentDuration: Double

  Present animation duration. Default is 0.5 sec

• popupShouldBeganDismiss: BOOL
