iPhone: Default compiler directive in Objective C

Question

If this question is repeated, please ignore it. but i couldn't find it repeated. In objective C, the default compiler directive is @protected not @public for class instance variables, is that right? Please correct me if i'm wrong.

Thank you.

Answer 1

[By] default, instance variables are visible in all instance methods of a class and its subclasses. This is referred to as @protected scope in Objective-C.

Answer 2

All instance variables without an explicit scope directive have @protected scope
