A photo gallery for iOS with a modern feature set. Similar features as the Facebook photo browser.
"A photo gallery can become a pretty complex component of an app very quickly. The EBPhotoPages project demonstrates how a developer could use the State Pattern to control the behavior of an interface with numerous features. This pattern grants the ability to create new behaviors for a custom implementation of the EBPhotoPages photo gallery without having to modify or understand much of the original source code. The goal was to design a photo gallery class that would smoothly support whatever use cases would be required in the future."
What is this?
EBPhotoPages is a photo gallery library for displaying pages of photos and their meta data in a scrollview. Users are able to zoom photos in and out, as well as create, edit or delete comments and tags, share or delete a photo, and report inappropriate photos. All photos and content are loaded asynchronously. User permissions for a photo are controlled through a delegate protocol. No graphic files are required for the gallery as icons are drawn in code.
The library was designed using a state pattern to control the behavior of the gallery, so that other developers can easily modify or add new states without having to understand too much of the original code.
