David is right about returning a pointer, you probably only need to
return obj since obj is most likely a pointer to an object anyway.
You'd only need to return *obj if obj is a pointer to a pointer to an
object. I guess you don't want to return &obj since that would be an
object ** and your method is declared as returning an object *.
Anyway, here's my contribution: you are not calling the right
function. -function: as you have implemented it takes an argument,
but you are calling a method -function which does not take any
arguments. You should call it like this:
obj2=[outlet function:self];
but since function: does not do anything with the argument, you could
get rid of it altogether, and change it to:
declaration:
- (object *) function;
implementation:
-(object *) function
{
return obj;
}
call:
obj2 = [outlet function];
