Question: I'm working on an app for a client and the client wants absolutely everything to be shareable (using sharekit). One of the views that the client wants is a photo gallery that can be easily updated and viewed. I've looked around at folks who have done this and I particularly like the way the Obama 2012 app does it using flickr. This brings me to the question, I'm trying to use the flickr api to display a photo gallery that will allow sharekit to share the url to the image but am hitting a brick wall. I've searched for a few days now and haven't found a tutorial that shows a working example in the way I need it, if anyone has done something similar or knows a good tutorial that would be greatly appreciated.

Answer: 
Download the list of images using the Flickr API, and asynchronously add them to a UIScrollView inside a UINavigationController with its back button as "back". Then add a UIToolBar which has the items 'Next' and 'Previous' (use images). That will give you the look of a photo gallery. 

Also, I came across this which is basically what I told you to do, but open source: <http://www.cocoacontrols.com/platforms/ios/controls/fgallery>
I wrote a tutorial on building a media gallery using a UICollectionView. It populates from the user's photo library, but is definitely more extensible than using a 3rd party.
