Protocol

NSObjectProtocol

The group of methods that are fundamental to all Objective-C objects. 全てのObjective-Cオブジェクトにとって基本的なメソッドのグループ。

Declaration 宣言 

protocol NSObjectProtocol

Overview 概要

An object that conforms to this protocol can be considered a first-class object. Such an object can be asked about its:

  • Class, and the place of its class in the inheritance hierarchy.

  • Conformance to protocols.

  • Ability to respond to a particular message.

The Cocoa root class NSObject adopts this protocol, so all objects inheriting from NSObject have the features described by this protocol.

Object Basics オブジェクト基礎

class NSObject
The root class of most Objective-C class hierarchies, from which subclasses inherit a basic interface to the runtime system and the ability to behave as Objective-C objects. たいていのObjective-Cクラス階層のルートクラス、そこからサブクラスは基本的なインターフェイスとObjective-Cオブジェクトとして振舞う能力を継承します。
NSKeyValueCoding
A mechanism by which you can access the properties of an object indirectly by name or key. それによってあなたがあるオブジェクトのプロパティに名前またはキーによって間接的にアクセスできるある仕組み。
