Feature request: Notification when new data came from iCloud

[artemyarulin]

Hi there,

Thanks for the good library. I have a special case when I need to do some processing when new data came from the iCloud. What do you think about firing new notification here SDCloudUserDefaults.m#L140, like:

[[NSNotificationCenter defaultCenter] postNotificationName:SDCLOUD_NOTIFICATION_KEY_UPDATED
                                                    object:self
                                                  userInfo:@{key:obj}];

I can create a pull request for that if you wish. Thanks!

Any reason why you can't just subscribe to NSUbiquitousKeyValueStoreDidChangeExternallyNotification directly?

Well, in short your library is a perfect additional abstraction for iCloud, I don't know how it works, I don't want to think about error processing, hell I have no idea what is NSUbiquitousKeyValueStoreChangeReasonKey.

My case is simple as "notify me when new data came from iCloud". Subscribing to NSUbiquitousKeyValueStoreDidChangeExternallyNotification direclty:

• forces me to implement basically all the things about error processing
• makes me dependent to iCloud implementation and for your library as well
• forces me to be sure that your library subscribes first for this notification, otherwise I would get old data in NSUserDefaults.

In real world I know that I can implement this in 10 minutes, it is not big deal, but it is not... elegant.

That's fair. And it would be completely benign for people who don't care.

I would welcome a pull request. Otherwise I'll look to add this when I get the chance.
