Hi all,
I think I may have misunderstood something about how super works. In trying to
build a dictionary that contains key/value pairs from the class itself as well
as super classes up to an arbitrary height, I've hit a wall. Simplified, I have
two classes, SuperClass and SubClass. In
hi,
why not try something like :
if ( [self isKindOfClass:[SuperClass class] ] )
{
}
so your test will not depend on instance but on 'typeof'
usually in code you use 'super' to verify that some data in 'super' already
exist or need to be initialised between testing super self

First of all, I agree with claw that this line looks really weird, although it
might work. I've just never seen it done that way.
if ([self class] == [SuperClass class]) {
Second, are you sure that SubClass inherits from SuperClass? Is it declared
like this? …
@interface SubClass :
also,
NSEnumerator *keyE = [[super tagDict] keyEnumerator]; //HERE
it is not a good strategy to use NSEnumerator at this point
what if super does not respond at all ?? . to avoid crash infinite loop
you needs to specify 'forward messaging' ( another instance object that will
respond to
super is relative to the class where this code is implemented (SuperClass)
which means the method lookup starts with the super class of SuperClass. This
true even when the code is called from a subclass.
You're getting the unrecognized selector sent to instance message because the
super class
super does not change what class the object thinks it is an instance of.
(It's different from C++ in this way, if I remember my C++.) If an object is an
instance of class X, [self class] *always* returns X.
Suppose you call [obj tagDict] where obj is an instance of SubClass. This is
what
Thanks for the suggestions, all.
I think this will probably suit my needs for now.

Thanks for the suggestion, but I should mention that it needs to be an
