A sample iOS project for ADI DevFest 2013.

This project uses features only available in iOS 6+. Make sure you have the latest version of Xcode and the iOS SDK installed.

1. Register for a Flickr API key.

2. Create a new file at Photos/CSPhotosAPIClientConstants.m with the following contents:

    #import "CSPhotosAPIClientConstants.h"
    NSString *const kCSPhotosAPIKey = @"<your API key here>";
   

3. Build and run!

Here are a couple of possible fun/educational ways one could modify this project:

• Add paginated results to the photo list view (by modifying CSPhotosAPIClient and CSPhotosViewController).
• Add the ability to search Flickr for a specific tag (or tags) using UISearchDisplayController.
• Add more aggressive image caching for a better offline viewing experience.
• Add Core Data for photo metadata persistence and background API response importing for improved UI performance.
• Display additional information about the photos, and about the users who posted them.
• Change the layout properties of the collection view in CSPhotosViewController (by subclassing UICollectionViewLayout).
• Use an entirely different photos API (like Facebook).
