Since never occurred previously, soma advice is needed.
If I would like to use
NSSortDescriptor
which is availbale on 10.3 as base of some new class , but not before,
how do I have to code, such that my code will not crash.
In a 10.2 environment, the respective part of code - which uses the
SortDescriptor -
will not be called. Thus, no problem regarding message dispatching
should
occur. Since some 10.3 callback will not be called in 10.2.
But how about linking? Will the app crash due to unresolved symbols?
