FSImageViewer is a photo viewer (gallery) for iOS.

It's initially based on EGOPhotoViewer, but completely refactored to use ARC, AFNetworking 2.5+ for remote image downloads and EGOCache 2.1 for image caching.

If you must use AFNetworking 1.3 you can use the 1.x version of FSImageViewer (https://github.com/x2on/FSImageViewer/tree/1.x)

Install

Using CocoaPods:

pod 'FSImageViewer', '~> 3.4'

Basic usage

Create your image objects:

FSBasicImage *firstPhoto = [[FSBasicImage alloc] initWithImageURL:[NSURL URLWithString:@"http://example.com/1.jpg"] name:@"Photo 1"];
FSBasicImage *secondPhoto = [[FSBasicImage alloc] initWithImageURL:[NSURL URLWithString:@"http://example.com/2.jpg"] name:@"Photo 2"];

And add them to the data source:

FSBasicImageSource *photoSource = [[FSBasicImageSource alloc] initWithImages:@[firstPhoto, secondPhoto]];

And create and show the view controller:

FSImageViewerViewController *imageViewController = [[FSImageViewerViewController alloc] initWithImageSource:photoSource];
[self.navigationController pushViewController:imageViewController animated:YES];

If you like to use a modal view controller:

FSImageViewerViewController *imageViewController = [[FSImageViewerViewController alloc] initWithImageSource:photoSource];
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:imageViewController];
[self.navigationController presentViewController:navigationController animated:YES completion:nil];

Advanced usage

You can also create your own image class by implementing the FSImage protocol and your own datasource by implementing the FSImageSource protocol.
