Well, the extra-super-defensive approach would be to not only check respondsToSelector:, but to check that the method signature of the object's implementation matches what's declared in the protocol. :) But yeah, you can't rely on conformsToProtocol: if you don't have the luxury of making the relevant classes conform to the protocol. --Andy _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
