how to use delegates with Automatic Reference Counting

Question

I\'ve jumped on the ARC bandwagon. In the past I would have my delegate properties declared like this:

@property(assign) id delegate;


        

Answer 1

"ivar" means "instance variable", which you have not shown. I'm betting it looks something like this:

@interface Foo : NSObject {
    id delegate;
}

@property (weak) id delegate;

What the error is saying is that it must look like this:

@interface Foo : NSObject {
    __weak id delegate;
}

@property (weak) id delegate;

If the property claims to be weak, the ivar that the value ends up being stored in must be weak as well.
