Well, there is, if you mean that you make the decision — -[NSProcessInfo isOperatingSystemAtLeastVersion:]. I’m not sure I understand, though, why you want to have this decision made. If you wrote code to make ‘assign’ (aka ‘unowned’) work in 10.6, that code — manual zeroing of the reference, I mean — will necessarily work in later versions, so why not just go with that unconditionally? OTOH, if you have a good reason for wanting to use ‘weak’ instead, it seems to me that’s a good reason to withdraw support for 10.6**, or at least to have a separate build for clients that want to run on 10.6. ** I’m not sure I remember now, but didn’t 10.6.8 have support for zeroing weak references? If that’s so, you could just withdraw support for 10.6.7 or earlier, which shouldn't upset anyone greatly. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
