Improve Performance with Native C/C++

Abstract

In this chapter, you will learn about:

• The benefits and costs to integrating C/C++ code into your iPhone application.

• Basic concepts in C programming

  • Data types

  • Pointer

  • Memory management

• Basic concepts in C++ programming

  • Class

  • Memory management

  • Inheritance

  • Template

• ■ How to work through a real example with SQLite, a database that has a C API.

• How to integrate C++ and Objective-C++ into your iPhone application. In this chapter, you will learn about low-level programming with C/C++, which is important for high performance applications. It’s true that Objective-C is a superset of C and also a native programming language, but Objective-C adds a wrapper over the C language that reduces performance. If you have ever worked with games and animations, you know that using OpenGL with C/C++ provides much better performance.
