Options: A) Bump the SDK setting to 10.6, keeping the deployment target at 10.5. Don't call any 10.6-only methods when running on 10.5. (i.e. check -respondsToSelector: or similar) B) Declare the new methods as categories in headers, but don't actually implement the methods. That will tell the compiler how to call those new methods. Once again, don't call 10.6-only methods while running on 10.5 C) Fallback to older, deprecated APIs. e.g. -directory _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
