- Zeta Components
You can also import your own API's generated by yourself with ApiGen. Just compress your API as a ZIP file and synchronize it with iTunes File Sharing or use the "Open in…" dialog (e.g. in Mail) to open it with ApiGen Reader. If an API is included within an SDK, you can also synchronize the complete SDK. ApiGen Reader will extract the API automatically and clean up unnecessary parts.
Of course you can use ApiGen Reader on you iPad and iPhone without any extra cost.
