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: [

.package(url: “https://github.com/joomcode/BottomSheet”, from: “2.0.0”)

]

CocoaPods

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


                                              
                                                $ bundle install

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:

Create UIViewController to present and set content’s size by preferredContentSize property
(optional) Conform to ScrollableBottomSheetPresentedController if your view controller is list-based
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 dismiss completion if user closed bottom sheet by a gesture

}

)
