How can you connect to an iTunes library in 开发者_开发知识库your iPhone program? What API or classes are used in this? I need to make an app similar to the REMOTE app that exists: to be able to connect to an iTunes library on someones computer and see their list of songs etc.

I don't think that's possible. The remote API has been reverse-engineered for the Android iTunes remote at http://dacp.jsharkey.org/ but I don't believe for a second that Apple would allow such an app on the App Store.

Accessing the music stored in a remote iTunes library is not directly possible (without installing additional software alongside iTunes). DAAP, the protocol used by iTunes to share music, has not yet been successfully reverse-engineered, and if you managed it, not only would Apple reject your app, they'd probably ban you and maybe sue you.

Your best bet would probably be to write a server app that runs alongside iTunes.
