Photo viewers are common in so many different apps, however programming a photo viewer with all the desired functionality such as zooming, and flicking is somewhat tedious.

This is where the cool Three20 library comes in which I’ve mentioned several times on this site.

Unfortunately several of the guides that were available on using this library have now disappeared, and because of that many have not been introduced to the tremendous versatility of this great open source library.

Fortunately for us all Ray Wenderlich, the creator of the Space Game Starter Kit and co-author of the Learning Cocos2D book, has created a great step-by-step guide to using the Three20 photo viewer (TTPhotoViewController).

The guide goes through everything that you can do with the Three20 photo viewer and starts at the beginning showing you how to implement the class in your projects all through sourcing your photos, and displaying the final result.

You can check out the guide on Ray’s website at:
How To Use The Three20  Photo Viewer

You can also find some more guides on using Three20 here:

Btw, if you’ve written an iOS programming guide feel free to submit it, or a link to it here and if I think the readers will like it I’ll feature it on the site in front of our 2,000+ daily visitors.
