Native Signup for iPhone Apps
ChimpKit is a complete Objective‑C wrapper that corresponds one‑to‑one with the MailChimp API. Reference the API calls you want to include in the app, and you’re ready to go. You can even drop ChimpKit’s standard signup‑form code right into your app without any modification.
Stay in touch with your users, keep them informed about updates, and introduce them to all the exciting things you’re developing.
