Are there APIs or other methods to communicate with Mac OS X and iOS(iPhone and iPad)?

I want to know whether there开发者_如何学Go are APIs or other methods to communicate with Mac OS X and iOS. I have googled the problem and found no results. Moreover, someone said there is no official support for it. Any help would be appreciated:)

You can use just about any network protocol from Bonjour to ZMODEM to communicate between an iOS device and a Mac. HTTP is, of course, one very popular choice. As a bonus, most options work equally well to talk to devices running Windows and unix-y operating systems.
