An image gallery for iOS

RIGImageGallery is a photo gallery meant to provide most of the functionality of the image gallery in the system Photos app, and handle asynchronous loading of images.

This library is part of the Raizlabs Interface Guidelines, which are UI components that offer sensible defaults to help a project get off the ground quickly with components that feel native to the platform, and with easy to use customization options.

Usage example

To see a complete example of using the gallery, take a look at the sample project.

Creating a Gallery from Image URLs

func createPhotoGallery() -> RIGImageGalleryViewController {

    let urls: [URL] = [

    let rigItems: [RIGImageGalleryItem] = urls.map { _ in
        RIGImageGalleryItem(placeholderImage: UIImage(named: "placeholder") ?? UIImage(),
                            isLoading: true)

    let rigController = RIGImageGalleryViewController(images: rigItems)

    for (index, URL) in urls.enumerated() {
        let request = imageSession.dataTask(with: URLRequest(url: URL)) { [weak rigController] data, _, error in
            if let image = data.flatMap(UIImage.init), error == nil {
                rigController?.images[index].image = image
                rigController?.images[index].isLoading = false

    return rigController

Presenting and Customizing the View Controller

@objc func showGallery(_ sender: UIButton) {
    let photoViewController = createPhotoGallery()
    photoViewController.dismissHandler = dismissPhotoViewer
    photoViewController.actionButtonHandler = actionButtonHandler
    photoViewController.actionButton = UIBarButtonItem(barButtonSystemItem: .action, target: nil, action: nil)
    photoViewController.traitCollectionChangeHandler = traitCollectionChangeHandler
    photoViewController.countUpdateHandler = updateCount
    let navigationController = UINavigationController(rootViewController: photoViewController)
    present(navigationController, animated: true, completion: nil)

func dismissPhotoViewer(_ :RIGImageGalleryViewController) {
    dismiss(animated: true, completion: nil)

func actionButtonHandler(_: RIGImageGalleryViewController, galleryItem: RIGImageGalleryItem) {

func updateCount(_ gallery: RIGImageGalleryViewController, position: Int, total: Int) {
    gallery.countLabel.text = "\(position + 1) of \(total)"

func traitCollectionChangeHandler(_ photoView: RIGImageGalleryViewController) {
    let isPhone = UITraitCollection(userInterfaceIdiom: .phone)
    let isCompact = UITraitCollection(verticalSizeClass: .compact)
    let allTraits = UITraitCollection(traitsFrom: [isPhone, isCompact])
    photoView.doneButton = photoView.traitCollection.containsTraits(in: allTraits) ? nil : UIBarButtonItem(barButtonSystemItem: .done, target: nil, action: nil)
