id is the answer if all your ivars are NSObjects. Just create
NSObject wrappers for your other types.

Is id the answer? I hear it's the "generic type", but haven't seen
good examples of it's use. If so, I'm not sure how to use id (proper,
declaration, initialization, pointing, referencing, etc.).
If not id, then how do I accomplish this dynamic ability for instance
variables to be pointers to any type of data?
@interface DynamoClass : NSObject
{
id pointerOne;
id pointerTwo;
id pointerThree;
}
- (id)initWithString:(NSString *)dataType;
@end
Thanks for any pointers. ;
