Objective-C dynamic_cast?

Question

Is there an Objective-C equivalent of C++\'s dynamic_cast?

It can be faked using this:

MyClass *safeObject = [object isKindOfClass: [MyClass class]]
         


        

Answer 1

Try this macro:

#define objc_dynamic_cast(obj, cls) \
    ([obj isKindOfClass:(Class)objc_getClass(#cls)] ? (cls *)obj : NULL)

And also don't forget to

#include 

Use it like:

MyClass *safeObject = objc_dynamic_cast(originalObject, MyClass);
