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.
Variables are used to store data that can be used later in the program.
int variableName = value;
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 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 allow the program to repeat a set of instructions.
for (int i = 0; i < 10; i++) {
// code to be executed
}
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
