Objective-C Cheatsheet

Objective-C is a programming language used primarily for developing applications for Apple’s Mac OS X and iOS operating systems. Here is an overview of its features, code blocks, and resources.

Features

Code Blocks

Variables

Variables are used to store data that can be used later in the program.

int variableName = value;

Methods

Methods are code blocks that perform a specific task. They can be called by other parts of the program.

-  (void)methodName:(parameterType)parameterName {
    // code to be executed
}

Conditionals

Conditionals allow the program to make decisions based on certain conditions.

if (condition) {
    // code to be executed if condition is true
} else if (otherCondition) {
    // code to be executed if otherCondition is true
} else {
    // code to be executed if neither condition is true
}

Loops

Loops allow the program to repeat a set of instructions.

for (int i = 0; i < 10; i++) {
    // code to be executed
}

Objects

Objective-C is an object-oriented programming language, and objects are a fundamental part of the language.

@interface ClassName : SuperclassName
// properties and methods
@end

@implementation ClassName
// implementation of methods
@end
