For that you really only need a method in one place. I'd be inclined to put it
in NSNull:
+ (id)nullIfNil:(id)obj
{
return obj ?: [self null];
}
And then in constructing your dictionary you'd have code like
NSDictionary *myLookup = @{ key1, [NSNull nullIfNil:value1],
key2, [NSNull nullIfNil:value2],
... };
For brevity I might not use a method at all; since this is a special case where
there is only one variable, a function or macro is much less clunky:
NSDictionary *myLookup = @{ key1, ObjOrNull(value1),
key2, ObjOrNull(value2),
... };
