Expose a private Objective-C method or property to subclasses

Question

According to some official talk, a class in Objective-C should only expose public methods and properties in its header:

@interface MyClass : NSObject

@prope         


        

Answer 1

That's because there's not even a real distinction between private and public. While the compiler may warn you about an interface missing a certain method or instance variable, your program will still work.
