Is the superclass your code? If it is, just move the class extension (i.e. @interface MyClass () ... @end) to a separate file named MyClassPrivate.h, add declarations for any private methods the subclass needs to call, and have the subclass import that. If the superclass is not your code, then it's best to find a way to do what you need without calling the private methods.
