GSON for objective-c (or as close as it can be). I tried to make this function as similar as possible to GSON. Reason? GSON is amazing and once you don't have to create your own objects from JSON you'll never want to again.
Currently serializes NSObjects into a JSON string and will deserialize back into NSObjects.
Date serialization/deserialization not implemented yet.
You must call iSON registerObjectByPropertyName:forClass for all NSArray's inside of your objects that you want to deserialize.
Sadly objective-c has no type casting of arrays which is why this partial mapping is required.
If the property name is not found for an NSArray it will throw an exception for you to register it with iSON.
objectToJSON: will serialize any object into a JSON NSString
You must use NSWrapper's for this. NSNumber, NSString, NSObject, NSArray, NSDictionary will all work.
If you submit a property as nil it will convert it to null in the JSON string.
objectFromJSON:forClass will deserialize your JSON String to an NSObject. You must specify the class of this object
for it to deserialize correctly. (THIS METHOD WILL NOT WORK WITH UNNAMED JSON ARRAY'S)
objectFromUnnamedArrayJSON:ForClass: will allow you to convert an unnamed JSON Array to an NSArray of objects
