`-Wprotocols' is the default which requires them defined.
+load
===========
This method, if defined, is called for each class and category
implementation when the class is loaded into the runtime. This method
is not inherited, and is thus not called for a subclass that doesn't
define it itself. Thus, each +load method is called exactly once by
the runtime. The runtime invocation of this method is thread safe.
+initialize
===========
This method, if defined, is called before any other instance or class
methods of that particular class. This method is not inherited, and
is thus not called as initializer for a subclass that doesn't define
it itself. Thus, each +initialize method is called exactly once (or
never if no methods of that particular class is never called).
Besides this, it is allowed to have several +initialize methods, one
for each category. The order in which these (multiple methods) are
called is not well defined. I am not completely certain what the
semantics of this method is for other implementations, but this is
how it works for GNU Objective C.
methods of that particular class. For the GNU runtime, this method is
not inherited, and is thus not called as initializer for a subclass that
doesn't define it itself. Thus, each +initialize method is called exactly
once by the runtime (or never if no methods of that particular class is
never called). It is wise to guard against multiple invocations anyway
to remain portable with the NeXT runtime. The runtime invocation of
this method is thread safe.
