objective-c - 子类是否继承了 Objective-C 中其父类的协议(protocol)？

Question

假设我有一个实现协议(protocol)的父类:

@interface GameViewController : UIViewController<GamePrizeDelegate> {
  ...
}

然后我创建它的子类:

@interface TennisViewController : GameViewController {
  ...
}

@interface SoccerViewController : GameViewController {
  ...
}

我是否还必须在子类中包含 GamePrizeDelegate？协议(protocol)是否也被继承？

谢谢!

引用Apple's documentation : 你的子类确实继承了协议(protocol)的采用，所以你不必再次采用它。

Conforming to a Protocol

A class is said to conform to a formalprotocol if it adopts the protocol orinherits from another class thatadopts it. An instance of a class issaid to conform to the same set ofprotocols its class conforms to.
