Installation

CocoaPods is the most common solution to install this library.

1. Add pod 'VTAcknowledgementsViewController' 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).

Initialization

The VTAcknowledgementsViewController instance is usually pushed to an existing UINavigationController.

VTAcknowledgementsViewController *viewController = [VTAcknowledgementsViewController acknowledgementsViewController];
[self.navigationController pushViewController:viewController animated:YES];

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.

viewController = [[VTAcknowledgementsViewController alloc] initWithFileNamed:@"Pods-MyTarget-acknowledgements"];

NSString *path = [[NSBundle mainBundle] pathForResource:@"Pods-MyTarget-acknowledgements" ofType:@"plist"];
viewController = [[VTAcknowledgementsViewController alloc] initWithPath:path];

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

VTAcknowledgement *customLicense = [[VTAcknowledgement alloc] initWithTitle:@"..." text:@"..." license:nil];
viewController = [[VTAcknowledgementsViewController alloc] initWithAcknowledgements:@[customLicense]];

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. If these texts contain a link, the view is tappable, and opens a browser with the URL.

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.

NSString *localizedTitle = [VTLocalization localizedTitle]; 
[button setTitle:localizedTitle forState:UIControlStateNormal];

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

viewController = [[VTAcknowledgementsViewController alloc] initWithAcknowledgements:@[] style:UITableViewStylePlain];

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

Apple TV

VTAcknowledgementsViewController is also compatible with tvOS for Apple TV apps.

Requirements

VTAcknowledgementsViewController supports iOS 9.0 or tvOS 9.0 and above, and requires Xcode 11.0 and above. If you need lower requirements, look for an older version of this repository.
