Hi,
I've a object like to following:
@interface <Proto> {
NSMutableArray *items;
}
@property (nonatomic,readonly) NSMutableArray *items;
@end
I also have a protocol as follows:
@protocol Proto
@property (nonatomic,readonly) NSArray *items;
@end
I of course want the items to be read only for the outside world, but the
object itself should be able to modify it. Now the compiler complains about the
properties not matching. How should I solve this? Make a custom getter that
returns an immutable array? Make the property refer to a mutable array? Make
the property an immutable array and make copies of the array while modifying it?
Any insight would be appreciated.
Kind regards,
Remco Poelstra
