BottomSheet

A BottomSheet component made with UIKit.

BottomSheet

Usage

BottomSheetViewController

This controller uses BottomSheetView as its main view. To specify custom content for the bottom sheet create your own view, and assign it to the contentView variable of the controller. You can either do this by subclassing BottomSheetViewController, to implement your own business logic, or by assigning the view at initialisation before presenting the sheet.

Example: subclassing BottomSheetViewController

final class CustomBottomSheetViewController: BottomSheetViewController {
    override func loadView() {
        super.loadView()
        	
        let myView = UIView()
        myView.backgroundColor = .red
		
        contentView = myView
    }
}
Swift

Example: assignment on init

func presentBottomSheet() {
    let controller = BottomSheetViewController()
    controller.contentView = UIView()
    ...
}
Swift

Presentation

Instantiate your BottomSheetViewController and set the presenting controller as the transitioningDelegate of the bottom sheet.

final class ViewController: UIViewController {
    ... 
    
    func presentBottomSheet() {
        let controller = BottomSheetViewController()
        controller.transitioningDelegate = self
        present(controller, animated: true, completion: nil)
    }
}

extension PresentingController: UIViewControllerTransitioningDelegate {
    func presentationController(forPresented presented: UIViewController, presenting: UIViewController?, source: UIViewController) -> UIPresentationController? {
        BottomSheetPresentationController(presentedViewController: presentedController, presenting: presenting)
    }
}
