When our iPhone app is launched for the first time, it checks the user's iCloud account to see if he has installed our app on another device. If so, he'll have a unique ID that we've stored in his iCloud account, which is a database key that we use to manage his online content. We grab it and store it in local user defaults.
If the user doesn't have an ID in iCloud, we create one, store it in local user defaults and save it to iCloud. During appDidFinishLaunching, I instantiate the ubiquitous store and call [synchronize]. After figuring out that we always have to listen for the NSUbiquitousKeyValueStoreDidChangeExternallyNotification (even though the external repository actually didn't change), I'm left with this question: How do I know if this call simply failed, or if the value is absent from the remote server? Will this notification be issued even if the key/value pair doesn't exist? If not, how do I ever know that key/value pair is absent from iCloud and that I won't be overwriting it if I store a new one there? Thanks for any insight.
