Bottom Sheet

Bottom Sheet component is designed to handle any content, including a scrolling one.

• ✅ use any content size, and it will adapt
• ✅ use scrollable content: UICollectionView, UITableView or UIScrollView
• ✅ dismiss interactively by swipe-down or just tapping on an empty space
• ✅ build flows inside using BottomSheetNavigationController
  • ✅ supports all system transitions: push and (interactive) pop
  • ✅ transition animated between different content sizes
• ✅ Customize appearance:
  • pull bar visibility
  • corner radius
  • shadow background color

Installation

Swift Package Manager

To integrate Bottom Sheet into your Xcode project using Swift Package Manager, add it to the dependencies value of your Package.swift:

dependencies: [

]

CocoaPods

CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:

To integrate BottomSheet into your Xcode project using CocoaPods, specify it in your Podfile:

source 'https://github.com/CocoaPods/Specs.git'
use_frameworks!

target '<Your Target Name>' do
    pod 'BottomSheet', :git => 'https://github.com/joomcode/BottomSheet'
end

Getting started

This repo contains demo, which can be a great start for understanding Bottom Sheet usage, but here are simple steps to follow:

1. Create UIViewController to present and set content's size by preferredContentSize property
2. (optional) Conform to ScrollableBottomSheetPresentedController if your view controller is list-based
3. Present by using presentBottomSheet(viewController:configuration:)

If you want to build flows, use BottomSheetNavigationController

presentBottomSheetInsideNavigationController(
    viewController: viewControllerToPresent,
    configuration: .default
)

You can customize appearance passing configuration parameter

presentBottomSheet(
    viewController: viewControllerToPresent,
    configuration: BottomSheetConfiguration(
        cornerRadius: 10,
        pullBarConfiguration: .visible(.init(height: 20)),
        shadowConfiguration: .init(backgroundColor: UIColor.black.withAlphaComponent(0.6))
    ),
    canBeDismissed: {
        // return `true` or `false` based on your business logic
        true
    },
    dismissCompletion: {
        // handle bottom sheet dismissal completion
    }
)
