Dear list, I'm wondering about whether or not an app that uses iCloud to sync a core-data store (shoe-box app) should have a user preference to disable syncing. Suppose the user doesn't want to sync across machines? I don't think they get a check-box in the iCloud system prefs pane, right?
And if it would be good practice to offer should a check-box to the user in the app's preferences, how would one go about enabling/disabling iCloud at run-time for an app using core data? Would it be enough to ignore the notifications? I guess not, since when the app relaunches it will see the transactions produced on other machines. So I guess the correct way is to create a new persistent store coordinator with/without the *Ubiquitous* keys and swap it in. And suppose the user has iCloud enabled in the app on one machine, but disabled on another machine, then the transaction logs would be generated. So how to ignore them on the machine where iCloud is disabled for the app? Would it be correct to create an NSPersistentStoreCoordinator where NSPersistentStoreUbiquitousContentNameKey and NSPersistentStoreUbiquitousContentURLKey are not set? Would that mean that that copy of the app would not get the NSPersistentStoreDidImportUbiquitousContentChangesNotification notifications and would it ignore the transaction logs? And what should one do when/if the user re-enables iCloud sync? Will the app catch up with the transactions? Has anybody thought about, or even better, solved these issues?
