Fully Customizable Dynamic Bottom Sheet Library for iOS.

This library doesn’t support storyboards.

However, you can easily override variables in DynamicBottomSheetViewController and make the bottom sheet programmatically.

Preview

Requirements

  • Swift 5

  • iOS 10.0 +

  • RxSwift 6.0

  • RxCocoa 6.0

  • RxGesture 4.0

  • SnapKit 5.0

  • Then 2.0

Installation

CocoaPods

DynamicBottomSheet is available through CocoaPods. To install
it, simply add the following line to your Podfile:

pod 'DynamicBottomSheet'

$ pod install

Swift Package Manager(SPM)

In Xcode, add as Swift package with this URL: https://github.com/Witi-Official/DynamicBottomSheet

Usage

  1. Import DynamicBottomSheet on top of your view controller file.

  2. Create a class for the bottom sheet where its super class is DynamicBottomSheetViewController.

  3. Put the view you want to show in the contentView of the super class DynamicBottomSheetViewController.

  4. Make constraints of the view you made to the contentView above.

  5. Present the bottom sheet view controller you made before in another view controller.

Example

For more examples, clone the repo, and run pod install from the Example directory.

import UIKit
import DynamicBottomSheet
import SnapKit
import Then

class MyStackViewBottomSheetViewController: DynamicBottomSheetViewController {

    // MARK: - Private Properties

    private let stackView = UIStackView()
        .then {
            $0.axis = .vertical
            $0.spacing = 32
            $0.alignment = .fill
            $0.distribution = .fillEqually
        }

}

// MARK: - Layout

extension MyStackViewBottomSheetViewController {

    override func configureView() {
        super.configureView()
        layoutStackView()
    }

    private func layoutStackView() {

        contentView.addSubview(stackView)
        stackView.snp.makeConstraints {
            $0.top.equalToSuperview().offset(16)
            $0.leading.equalToSuperview().offset(16)
            $0.trailing.equalToSuperview().offset(-16)
            $0.bottom.equalTo(view.safeAreaLayoutGuide).offset(-16)
        }

        Array(1...5).forEach {

            let label = UILabel()
            label.text = "\($0)"
            stackView.addArrangedSubview(label)

        }

    }

}

import UIKit

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()

        let bottomSheet = MyStackViewBottomSheetViewController()
        DispatchQueue.main.async {
            self.present(bottomSheet)
        }
    }
}
