OK, I know how to create a class extension, using something like that:

on .h

@interface UIButton (myExtensionName) 

// my extended methods

@end

and then on .m

@implementation UIButton (myExtensionName)

// my implementations

@end

But how do I declare the extended delegates I may create?

If this was a normal class I would do

@protocol myExtensionName <NSObject>
// my delegate declarations
@end

but how do I do that on a class extension?

thanks
