Method call in Objective-C

To call a method in a class in Objective-C, you need to create an instance (object) of that class and then call the method using the dot notation or square bracket notation.

Here's an example:

Suppose you have a class called Calculator with a method called addNumbers that takes two integers as input and returns their sum:

``objective-c @interface Calculator : NSObject


- (int)addNumbers:(int)num1 with:(int)num2;
@end
@implementation Calculator
- (int)addNumbers:(int)num1 with:(int)num2 {

    return num1 + num2;

}
@end



To call this method, you need to first create an instance of the Calculator class:
objective-c

Calculator *myCalculator = [[Calculator alloc] init];



Then, you can call the addNumbers method on the myCalculator object using either dot notation or square bracket notation:
objective-c

int sum = [myCalculator addNumbers:5 with:10];

NSLog(@"The sum is: %d", sum);
// or

int sum = myCalculator.addNumbers(5, 10); NSLog(@"The sum is: %d", sum);`

Both of these will call the addNumbers method on the myCalculator object, passing in the two integers 5 and 10, and returning their sum, which will be stored in the sum variable. The result will then be printed to the console using NSLog`.
