What is common case for @dynamic usage ?
- by Forrest
There is previous post about difference of @synthesize and @dynamic.
I wanna to know more about dynamic from the perspective of how to use @dynamic usually.
Usually we use @dynamic together with NSManagedObject
// Movie.h
@interface Movie : NSManagedObject {
}
@property (retain) NSString* title;
@end
// Movie.m
@implementation Movie
@dynamic title;
@end
Actually there are no generated getter/setter during compiler time according to understanding of @dynamic, so it is necessary to implement your own getter/setter.
My question is that in this NSManagedObject case, what is the rough implementation of getter/setter in super class NSManagedObject ?
Except above case, how many other cases to use @dynamic ?
Thanks,
