I am looking for the way to get the object’s members type name in sequence declared in the object header.

such as, if I get an object like this

@interface Person : NSObject {
  int age;
  NSString *name;
  PersonDetail *detail;
}

When I get the data like {28,@"Jack",{@"basketball",@"Male",@"Master Degree"}} in array.
I would need the type of members to fill the data in.

It’s like in java where there is a function like getField() to get the members in order.

So is there any methods I can use?

Thank.

Have a look at the Objective-C Runtime Reference. It includes functions for doing things like getting a class’s ivar list (class_copyIvarList()), or get an objects actual ivars (object_getIndexedIvars()) and things like that. It should be able to do something like what you want.
