No, this works fine in 64 bit (I use it in FileView); the important part is @public in the declaration of PublicClassIvars, which obviates the need for @defs since you already have access to _ivars from PublicClass. For true opaque objects, you'd use @dynamic, but then I think you have to use @property accessors...which would eliminate the private ivar object also.But PDFKit does not use @public, and the docs say not to use @defs.
How do you know it doesn't use @public, though, since you don't have the declaration of the ivar class? You can't know that from class- dump, as far as I can tell; it would show up in PublicClassIvars here:
/*
* File: a.out
* Arch: Intel x86-64 (x86_64)
*
* Objective-C Garbage Collection: Unsupported
*/
@interface PublicClass : NSObject
{
PublicClassIvars *_ivars;
}
- (id)init;
- (id)description;
@end
@interface PublicClassIvars : NSObject
{
id _representedObject;
long long _type;
}
@end
