Strict Type Checking in Objective-C via Macros

Question

Occasionally, during development/debugging, I want to ensure that an object is of a certain type:

PageTopBottom *newPage = [notification object];
assert([new         


        

Answer 1

The preprocessor only processes text; it has no knowledge of type, which is why it's sometimes considered 'dangerous'. The only way I could see doing it is wrapping the variable declarations in a macro, which I would strongly advise against, and probably wouldn't actually cut down on the code or complexity.

Also, shouldn't you check the type before casting?
