NSOperation* classes look like what I could definitely use, but the docs mention that NSOperation and NSOperationQueue are available for MacOSX 10.5 and above. I am developing on 10.4. And the question arose here, when the documentation states that a class is available for 10.5 and later does that mean that if I use this class my app is compatible only with mac osx 10.5 and later or does that mean that to take advantage of this class I must run 10.5 but once compiled it will run in previous versions of mac OS? _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
