Question

Documentation is not clear on how to use NSUbiquitousKeyValueStore with edge cases.

If I want to set a value, I understand that I should set a value to

Answer 1

I am using http://blog.mugunthkumar.com/coding/ios-code-mkicloudsync-sync-your-nsuserdefaults-to-icloud-with-a-single-line-of-code/

It is a simple class written by Mugunth Kumar (thanx !) that does the work for you... Unless you have special needs, add one line of code and it will do all the reading and writing to iCloud... all you need to do is read and write to NSUserDefaults as usual...

Edit:

Carful, if you remove an item from NSUserDefaults the code I linked to above will not remove the item from the cloud. Whenever you remove an item from NSUSerDefaults please do the same to NSUbiquitousKeyValueStore as So:

NSUbiquitousKeyValueStore* keyValueStore=[NSUbiquitousKeyValueStore defaultStore];
[keyValueStore removeObjectForKey: yourKey];

Answer 2

I wrote a simple iOS category that can be used to save a value also into NSUbiquitousKeyValueStore while storing into NSUserDefalt.

The Mugunth Kumar answer provided above works beautifully if you want to sync all of your NSUserDefaults!

However, it is an ALL or NOTHING approach. You can not pick or choose the defaults you wish to sync.

I found this Tutorial that may be of assistance if you are looking to be more picky.
