词汇表

Classes to define objects, which are composed of methods and variables. For programmers new to the language, it is important to understand that object-oriented programming (OOP) features are the keystone of all techniques used in Objective-C.

招惹

Inheritancee development concept that motivated the creation of the language. A chief feature of OOP is the ability to create new classes that inherit methods, variables, and properties from other existing classes. You see, then, that to master the language you need to attain a good working knowledge of the co

ARCHE

Blocks which can help to simplify and clarify the relationship between programming entities. In this chapter, you will learn how to create and use blocks, a syntactical feature that makes the language much easier and more expressive.

Dynamic Bindingr real needs. Code written in this language can enjoy the safety of compiler-checked expressions and method calls, where the compiler verifies every statement during the process of creating an executable. A lot of features, however, are runtime-driven, and this allows programmers to delay some decis

The Preprocessord to import header files, which are used to make class definitions available to other parts of the application. The preprocessor is also used to define macros, which can work both as constants or to perform simple substitution based on arguments.

Unit Testingt tests can also be created to verify that a piece of code complies with some particular requirement. For example, if you are creating a method that adds two numbers, a unit test can be written to verify that the response is correct for some particular cases. Although you cannot prove that a piece o

Debuggingve support in the task of identifying, reproducing, and fixing programming bugs. Xcode provides a complete solution for writing and debugging programs, which makes it much easier to find bugs in new or existing applications. In this chapter, I explain how to use these debugging features.
