Objective-C Tutorial Roadmap
Learn Objective-C with this complete tutorial roadmap. Covers syntax, data types, operators, OOP concepts, pointers, memory management, Foundation framework, and advanced Objective-C features.
Overview of Objective-C
Introduction to Objective-C Objective-C is an object-oriented programming language that extends the C language with additional features, primarily for use in macOS and iOS applications. It was origina
Variables and Data Types
Data Types in Objective-C In Objective-C, each variable is associated with a data type, and each data type requires a specific amount of memory in the system. A data type defines the kind of data a va
Operators in Objective C
The Objective-C language, built on top of C, retains many of the same operators as C. These operators are crucial for creating mathematical expressions and performing various operations. Operators act
Loops in Objective-C Loops
In programming, there are scenarios where you need to execute a specific block of code multiple times. Typically, program statements are executed in a linear sequence, where the first statement is fol
Functions
Defining and Calling Functions In Objective-C, functions are defined outside of any class or method and can be called from anywhere in the program where they are visible. Functions can accept paramete
Blocks in Objective-C
Blocks in Objective-C are a powerful tool that help simplify development by allowing you to write more concise and efficient code. Blocks are self-contained pieces of code that can be passed around an
Numbers in Objective-C
Numbers in detail In Objective-C, numbers are treated as objects instead of primitive data types like in other programming languages. This allows for a greater range of values and offers various metho
Arrays in Objective-C
Arrays in detail An Array is a data structure that holds similar types of data in contiguous memory. In Objective-C, arrays are single-variable collections used to store multiple elements of the same
Pointers in Objective-C
In Objective-C, pointers are variables that store the memory address of another variable. A pointer variable must be declared before use. The size of a pointer depends on the system architecture. Poin
String in Objective-C
Strings and Their Type Strings are a fundamental concept in programming, used to represent sequences of text. In Objective-C, strings are objects that store sequences of characters. These characters c
Structures in Objective-C
Objective-C is an object-oriented programming language that extends the C language with object-oriented capabilities. It follows a bottom-up approach and supports both procedural and object-oriented p
Preprocessors in Objective-C
Preprocessors and Their Types Preprocessors are essential tools that assist in tasks like reusability and conditional compilation. This article explores the role of preprocessors in Objective-C. What
Typedef in Objective-C
Typedef in detail A typedef allows us to assign a new name to an existing data type. For instance, typedef unsigned char CAT; makes CAT an alias for unsigned char, s
Type Casting in Objective-C
Type Casting and Their Types Objective-C is a programming language that was created in the 1980s and is widely used for developing software for the macOS and iOS platforms. One of Objective-C’s key fe
Error, Log and File Handling in Objective-C
Log Handling in Objective-C Objective-C is widely used for building applications on Apple’s macOS, iOS, and iPadOS platforms. Logging plays a vital role in software development, helping developers und
Command Line Arguments in Objective-C
Command Line Arguments in Detail In Objective-C, command-line arguments are text strings passed to a program when it runs from the command line. They provide input parameters or options that control t
Classes & Object in Objective – C
Objective-C is an object-oriented programming language widely used for developing applications for Apple platforms such as iOS, macOS, watchOS, and tvOS. In Objective-C, classes and objects form the c
Inheritance in Objective-C
Inheritance is a programming concept where a subclass or child class derives attributes and methods from a parent or superclass. This enables code reuse and allows subclasses to extend or override the
Data Encapsulation in Objective-C
Data Encapsulation in detail Encapsulation is a core concept in Object-Oriented Programming (OOP), designed to bundle data and the methods that operate on the data within a single unit, while shieldin
Categories in Objective-C
Categories in detail Categories are an essential concept in the Objective-C programming language. They enable developers to extend the functionality of existing classes without altering their original
Posing in Objective-C
In Objective-C, posing is a runtime mechanism that allows one class to completely replace another class so that all messages sent to the original class are handled by the posing class. The class that
Extensions in Objective-C
Extensions in detail In Objective-C, Extensions (also known as Class Extensions) are a special type of category where methods must be declared within the main implementation block of th
Dynamic Binding in Objective-C
Dynamic Binding in detail Dynamic binding refers to the process of linking a function call to its actual definition at runtime instead of compile time. In Objective-C, this feature allows greater flex
