ASPinboard is the Objective-C library for Pinboard that powers Pushpin. It uses modern Objective-C features (such as ARC and blocks), supports iOS 8.3+, and is dead-simple to integrate. As of January 2013, ASPinboard has full support for every endpoint in the Pinboard API, except posts/recent. The first thing you'll want to do is add the files in the ASPinboard directory to your application. Alternatively, you can drag and drop the Xcode project into your existing app, and create a workspace. It's really up to you.
