Objective-C Initializers

This repository demonstrates how initializers work in Objective-C.

Introduction

Initializers are special methods that prepare an instance of a class for use. In Objective-C, the NSObject class is the root class from which most other classes inherit. This means that understanding how to initialize instances of a class, starting from NSObject, is fundamental to working with Objective-C.

Subclassing and Initializers

The diagram below demonstrates a sequence of instance initialization calls for the following use case:
