Programatically access (your own) iCloud data from a desktop or from a server?

Question

I want to access and manipulate, FROM A SERVER OR FROM MY DESKTOP MACHINE, my iPhone's iCloud data programmatically.

For example...

Does anyone know if it is possible? Is there any API or mechanism by which I can use MY OWN iCloud username and password to access MY OWN iCloud data (from a desktop machine, or from a server).

I want to see and manipulate the actual data like photos, sms and contacts etc. I have seen some apps that do that. Can someone tell me how it is possible?

To be clear: the software I am trying to write is not intended for an iOS device, rather for on a server or on a desktop client (windows or mac).

Answer 1

I don't believe you will have access to the entirety of your iCloud data. The iCloud API generally uses a local sandbox container called a "ubiquity container" that is specific to your app (or a group of apps if you set it up that way). You can persist and retrieve to/from that local container and iOS manages the majority of syncing that container with iCloud.

To answer the rest of your question, just use the iCloud API or a project like iCloudDocumentSync to manage your interaction with iCloud.
