About

This is iOS Maps like anchored bottom sheet with configurable anchors and reusable BottomSheetView, that can be used inside provided modal controller or without it.

BottomSheetView supports all kinds of UIView's including UIScrollView and it's ancestors as a container view.

BottomSheetViewController is intended to be used as a modal presented controller.

To configure BottomSheetView you should use BottomSheetViewConfiguration struct like this:

let config = BottomSheetViewConfiguration(
    contentView: UIView(),
    parentViewController: self,
    defaultPosition: .middle(),
    positions: [.top(), .middle(), .bottom()],
    isSlidingToAppear: false,
    isPullIndicatorNeeded: true,
    closeButtonIcon: UIImage(named: "closeIcon"),
    isDismissAllowed: false,
    cornerRadius: 16
)

Supported anchors:

1. Top
2. Middle
3. Bottom
4. Fixed
5. By content

Each anchor has associated value, which will override default height for this anchor.
By content mode is not yet implemented, feel free to open a pull request.

Once configuration is done, you should create BottomSheetView like this:

let bottomSheetView = BottomSheetView(configuration: configuration)

If you want to use this view for some complex UI cases, BottomSheetView will handle the pan gesture and will notify BottomSheetViewDelegate in heightDidChange(to height: CGFloat) method

If you want to implement general pop-up behaviour, you should use BottomSheetViewController. Create and present it like so:

let bottomSheetViewController = BottomSheetViewController(bottomSheetView: bottomSheetView)
        
bottomSheetViewController.delegate = self
bottomSheetViewController.present(from: self)
