I am working an Mac OS version of an existing iOS App. The iOS App uses iCloud to share its data accross devices. Of course this data should be accessable from the Mac OS version as well. When implementing the iCloud functionality in the iOS App the Stanford videos have been a great help. The iOS App uses a UIManagedDocument to setup the Core Data stack and handle all the iCloud related stuff.

Unfurtunatly there is no "UIManagedDocument class for Mac OS" wich does the same thing. NSPersistantDocument integrates the Core Data framework but is not designed to work with iCloud. Thus I am not sure how I can access/use the UIManagedDocument data in iCloud from within the Mac OS App.

Access to iCloud from within the Mac OS App is no problem. After using URLForUbiquityContainerIdentifier: I can access the "iCloud Folder" and see all data wich is stored there. But seeing and using the data are two different things.

Is there any example that demonstrates to how use iCloud from iOS AND Mac OS?

Thank you very much!e

  • Thank you for the hint. I know that using I am not forced to use UIManagedDocumen on the iOS side. But it makes things a little less complicated and (what is more important) this is solution is already up and running. Since iCloud is quite fragile I would like to avoid any changes to the current (running) implementation. Thus the first thing I am looking for is a solution to access the UIManagedDocument data send from the iOS app to iCloud from an Mac OS app. Only if anything else fails I would have to use an other solution. Any hint how to use the existing solution from Mac OS? – Andrei Herford Apr 05 '13 at 07:01
