3. Classes, Objects, and Methods
In this chapter, you learn about some key concepts in object-oriented programming and start working with classes in Objective-C. You need to learn a little bit of terminology, but we keep it fairly informal. We also cover only some of the basic terms here because you can easily get overwhelmed. Refer to Appendix A, “Glossary,” at the end of this book, for more precise definitions of these terms.
