Round and round I go....
I get a different set of warnings now.
I have a protocol:
@protocol MyProtocol <NSObject>
@end
this fixes the does not conform to the NSObject warning and the -
retain warning.
However, when I derive from that protocol:
@interface MyObj : NSObject <MyProtocol>
@end
I then get tons of warnings that my object doesn't have
implementations of all the NSObject methods.
What am I missing?
Thanks!

Hi Ofri,
Thanks for the tip. I can't actually cast it to (MyClass*) as that
is actually private to the server, only the protocol is visible to
the client. When I cast it to NSObject that didn't remove the
warning. Interestingly it only seems to happen for one of my
protocols.
I also get the following warning:
warning: type 'id <MyProtocol>' does not conform to the 'NSObject'
protocol
Any ideas on that?
You could make your protocol conform to the NSObject protocol, like
so:
@protocol MyProtocol <NSObject>
/* methods */
@end
Thanks!

You can either cast the proxy of the object to (MyClass *) or to
declare it as id <NSObject>. The first option will save some other
potential warnings for you at the same time.
I hope this helps,

I have a server app that vends a single object. From that object
you can iterate over several objects. Each time I return a new
object as an ID I want to stor e it on the client side as a member
variable of a client object. If I don't retain it I get crashes
as the object goes away. If I retain it, I watch the ref count go
up and everything works. However I am worried in that xcode tells
me this:
warning: '-retain' not found in protocol(s)
That makes me nervous. What is the correct way to store a local
copy of an object on the client side?
