Installation

CocoaPods

1. Add pod 'AcknowList' to your Podfile.
2. Run pod install.
3. Add the Pods-#target#-acknowledgements.plist file generated by CocoaPods to your main target: drag and drop the file from the Pods/Target Support Files/Pods-#target#/ folder in your Xcode project (don’t copy the file, leave Copy items if needed unchecked).

Swift Package Manager

AcknowList can be installed with the Swift Package Manager (requires Xcode 12 for localized resources).

1. Click on File → Swift Packages → Add Package Dependency….
2. Enter https://github.com/vtourraine/AcknowList.
3. Select the version you’d like to use.

Initialization

The AcknowListViewController instance is usually pushed to an existing UINavigationController.

let viewController = AcknowListViewController()
navigationController.pushViewController(viewController, animated: true)

By default, the controller will try to guess the name of your .plist file, based on the bundle name (Pods-#bundle-name#-acknowledgements.plist). If that doesn’t match the file you’re looking for, you can initialize the view controller with a custom file name or path.

let viewController = AcknowListViewController(fileNamed: "Pods-AcknowExample-acknowledgements")

let path = Bundle.main.path(forResource: "Pods-AcknowExample-acknowledgements", ofType: "plist")
let viewController = AcknowListViewController(plistPath: path)

If you want to include licenses that are not part of a .plist file, you can create new Acknow instances, and use them for the acknowledgements array of the controller.

let acknow = Acknow(title: "...", text: "...")
let viewController = AcknowListViewController(acknowledgements: [acknow])

Customization

The controller can also display a header and a footer. By default, they are loaded from the generated plist file, but you can also directly change the properties values.

viewController.headerText = "We love open source software."
viewController.footerText = "Powered by CocoaPods.org"

The controller title is a localized value for “acknowledgements”. You might want to use this localized value for the button presenting the controller.

button.setTitle(AcknowLocalization.localizedTitle(), for: .normal)

By default, AcknowListViewController uses the “grouped” table view style. You can choose a different style:

let viewController = AcknowListViewController(plistPath: path, style: .plain)

If you need to further customize the appearance or behavior of this library, feel free to subclass its classes.

SwiftUI

AcknowList now offers a SwiftUI interface, which supports all the major platforms.

Instantiate a AcknowListSwiftUIView with a path to the plist file, or with an array of Acknow instances, and present this view from a NavigationView.
