The system enforces the following limitations for data you save to the iCloud key-value store:
Your app can have no more than 1024 keys in the iCloud key-value store.
The total amount of available storage space for all values is 1 megabyte.
The maximum size for a single value is 1 megabyte. Therefore, if you associate 1 megabyte of data with a single key, you can’t write other keys to the store.
