Implement Child Delegate in Parent?

How to implement Child's delegates in Parent?

Parent.h:

@interface Parent : NSObject

Child.h

#import "Parent.h"
@protocol ChildDelegate <NSObject>
- (void)someMethod;
@end

@interface Child : Parent

I cannot declare Parent's interface to be:

@interface Parent : NSObject<ChildDelegate>

since it need to import "Child.h" and it will be circular import.

How can i solve this?

You should declare protocol conformance in source files (with .m extension).

You can declare Parent class in Parent.h without conformance to ChildDelegate protocol.

@interface Parent : NSObject

And in your Parent.m file you can write something as following.

#import "Child.h"

@interface Parent() <ChildDelegate>

@end

@implementation Parent
// Your implementation code here
@end
