NYTPhotoViewer is a slideshow and image viewer that includes double-tap to zoom, captions, support for multiple images, interactive flick to dismiss, animated zooming presentation, and more.

Usage is simple, with the option for more complicated customization when needed through a delegate relationship. In the most basic implementation, just initialize the view controller with an array of photo objects and present it as normal:

NYTPhotosViewController *photosViewController = [[NYTPhotosViewController alloc] initWithPhotos:photos];
[self presentViewController:photosViewController animated:YES completion:nil];

NYTPhotoViewer may be installed via Carthage. To install it, simply add the following line to your Cartfile:

github "NYTimes/NYTPhotoViewer"

Then, following the instructions for integrating Carthage frameworks into your app, link the NYTPhotoViewer and FLAnimatedImage frameworks into your project.

If you don't want support for animated GIFs, you may instead link against only the NYTPhotoViewerCore framework.

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

pod 'NYTPhotoViewer', '~> 1.1.0'

This library requires a deployment target of iOS 8.0 or greater.

See CHANGELOG.md.

NYTPhotoViewer is written in Objective-C but is intended to be fully interoperable with Swift. You’ll need to include an Objective-C bridging header like this one from the sample Swift project.

If you experience any interoperability difficulties, please open an issue or pull request and we will work to resolve it.

NYTPhotoViewer draws feature inspiration from Facebook and Tweetbot’s image viewers. If this implementation isn’t to your liking, you may consider JTSImageViewController or IDMPhotoBrowser.

NYTPhotoViewer has a straightforward implementation using standard UIKit components. The viewer is a UIViewController and uses UIViewController transitioning APIs for the animated and interactive transitions, a UIPageViewController for horizontal swiping between images, and UIScrollView for image zooming.

It is intended to be used without the need for subclassing, and as such it accepts model objects conforming to a NYTPhoto protocol and provides ample opportunity for customization via the NYTPhotosViewControllerDelegate. Since standard APIs are used, the client has full control over the transitions and customization of the NYTPhotosViewController.
