the userInfo of an NSNotification is an NSDictionary, so of course you can’t
cast it to an Array. There’s no workaround, they aren’t the same thing at all.
If you want to pass an Array of Dictionaries in the userInfo, you need to put
it in the userInfo *dictionary* under a key, then retrieve it, then cast it.
