Does a subclass inherit the protocols of its parent class in Objective-C?

Question

Suppose I have a parent class that implements a protocol:

@interface GameViewController : UIViewController {
  ...
}

A

Answer 1

Referring to Apple's documentation: Your subclass does inherit the adoption of the protocol, so you don't have to adopt it again.

Conforming to a Protocol

A class is said to conform to a formal protocol if it adopts the protocol or inherits from another class that adopts it. An instance of a class is said to conform to the same set of protocols its class conforms to.
