将自定义对象序列化为NSDictionary或NSArray以使用NSJSONSerialization

Question

I've been looking for a way to serialize custom objects with NSJSONSerialization avoiding the use of third-party libraries, and I couldn't find any example. Is there any way of "automatically" create an NSDictionary and NSArray from an object, without having to create it typing in code all the object's member names yourself one by one and setting manually the values? I found a related post , but it is pretty old, things may have now changed.

Thanks

You can use KVC to ask any object for dictionaryWithValuesForKeys: which will give you a dictionary representation of the object.

If you need to change the property / key names then you want to do some mapping and (depending on what you're using the JSON for) you may find RestKit useful.
