If you’re an iOS developer and want to easily add Pinboard support for users with Pinbook installed, you can now do that using an open source class I’ve created called ALBPinbookActivity. In one or two lines of code you can have “Send to Pinbook” appear in your UIActivityViewController (sharing sheet) and pre-fill any information you want (title, tags, etc). The Pinbook option will only appear for users who have Pinbook installed. You can get ALBPinbookActivity on GitHub. If you end up using it in your app, make sure to let me know.
