How do I create delegates in Objective-C?

Question

I know how delegates work, and I know how I can use them.

But how do I create them?

Answer 1

Delegate :- Create

@protocol addToCartDelegate 

-(void)addToCartAction:(ItemsModel *)itemsModel isAdded:(BOOL)added;

@end

Send and please assign delegate to view you are sending data

[self.delegate addToCartAction:itemsModel isAdded:YES];
