An Objective-C Class for Working with Fractions
Now it’s time to define an actual class in Objective-C and learn how to work with instances of the class.
Once again, you’ll learn procedure first. As a result, the actual program examples might not seem very practical. We get into more practical stuff later.
Suppose that you need to write a program to work with fractions. Maybe you need to deal with adding, subtracting, multiplying, and so on. If you didn’t know about classes, you might start with a simple program that looked like this.
