I have not tried FROM_NILABLE, but I assume it would work, either returning nil in the case that the key wasn't in the dict or that the value in the dict was [NSNull null], and otherwise the object in the dict.

NILABLE is from https://github.com/phonegap/phonegap-plugins/blob/master/iOS/InAppPurchaseManager/InAppPurchaseManager.m
