Use NSObject<protocolname>. Instead of id<...>

I'm trying to implement a delegate pattern in my code, where the delegate conforms to a formal protocol. But when I make the delegate ivar id<MyProtocol> and try to send it performSelectorOnMainThread:..., it complains that that action is "not found in protocol(s).

I have a similar issue when trying to retain and release the delegate (which I think can sometimes be avoided but should be used for strict generality, right?).

Am I doing something wrong, like failing to declare my protocol correctly?

TIA,
Rick
