Okay, after reading some of the documentation on KVC coding, I understand (I think) that the point is to allow me to specify a property of an object with an NSString, then set/get that property value using KVC (i.e. valueForKey: or setValue:forKey:). But it seems like the fact that there's no way to specify (or grab) the value of the property in a generic-enough manner would be a problem - anyone using it would still have to know the data type of the property they want to access, and thus they might as well just use the accessors. I can see this would work if ObjC had a generic data type (like the 'variant' data type in VB/REALbasic), but AFAIK, ObjC doesn't have such, and valueForKey: returns an id, right? How can I determine what I get back? (i.e. what does the id pointer point to? an NSString? an NSNumber? NSDecimalNumber? NSData? another NSObject subclass?)
