Hi,
I have protocol X that is implemented by a few classes of my own. These
classes are not known directly to my main code but only through the protocol
(id<protocol>). When my main code tries to addObserver:self to the object
id<protocol>, i get a warning saying that my protocol does not implement it.
This would have worked if i used the real object behind. What should i do ?
Just add a method like addObserver in the protocol and in the real object
make the method just invoke the [super addobserver]. Or is there a better
way to solve it ?
thanks
mohan
