iPhone 平台开发指南 iPhone 平台开发是一门细腻的技术，需要开发者具备一定的基础知识和实践经验。下面是 iPhone 平台开发的一些重要知识点： 1. **开发环境**：Xcode 是 iPhone 开发的官方集成开发环境（IDE），它提供了代码编辑、编译、调试和模拟器等功能。 2. **开发语言**：Objective-C 是 iPhone 平台开发的主要编程语言，它是一种面向对象的编程语言，具有强大的功能和灵活性。 3. **SDK**：iPhone SDK（Software Development Kit）是 Apple 公司提供的一套开发工具集，包含了开发 iPhone 应用程序所需的所有库、框架和文档。 4. **应用程序架构**：iPhone 应用程序架构通常包括以下几个部分：应用程序delegate、视图控制器、视图、模型和持久层。 5. **界面设计**：iPhone 的界面设计需要遵循 Apple 的人类界面指南（Human Interface Guidelines），以确保应用程序的用户体验。 6. **多点触控**：iPhone 的多点触控技术允许用户使用多个手指来与屏幕交互，开发者需要根据实际情况来实现多点触控功能。 7. **Core Animation**：Core Animation 是 iPhone 平台上的动画框架，提供了高性能的动画效果和交互体验。 8. **Core Data**：Core Data 是 iPhone 平台上的数据存储框架，提供了高效的数据存储和检索功能。 9. **游戏开发**：iPhone 游戏开发需要使用到游戏引擎和物理引擎，例如 Unity 和 Unreal Engine 等。 10. **性能优化**：iPhone 应用程序的性能优化需要考虑到内存管理、缓存机制、图形处理和多线程处理等方面。 11. **安全性**：iPhone 应用程序的安全性需要考虑到数据加密、身份验证和访问控制等方面。 12. **测试和调试**：iPhone 应用程序的测试和调试需要使用到 Xcode 的调试工具和模拟器。 iPhone 平台开发需要开发者具备广泛的技术知识和实践经验，包括开发环境、开发语言、SDK、应用程序架构、界面设计、多点触控、Core Animation、Core Data、游戏开发、性能优化、安全性和测试与调试等方面。

Creating an iPhone Project

Xcode provides several iPhone-application project templates to get you up and running developing your

application. You can choose from these types of application:

■ Navigation-Based Application. An application that presents data hierarchically, using multiple screens.

The Contacts application is an example of a navigation-based application.

■ OpenGL ES Application. An application that uses an OpenGL ES–based view to present images or

animation.

■ Tab Bar Application. An application that presents a radio interface that lets the user choose from several

screens. The Clock application is an example of a tab bar application.

■ View-Based Application. An application that uses a single view to implement its user interface.

■ Utility Application. An application that implements a main view and lets the user access a flipside view

to perform simple customizations. The Stocks application is an example of a utility application.

■ Window-Based Application. This template serves as a starting point for any application, containing an

application delegate and a window. Use this template when you want to implement your own view

hierarchy.

If you need to develop a static library for use in an iPhone application, you can add a static library target to

your project by choosing Project > New Target and selecting the Static Library target template in the iPhone

OS/Cocoa Touch list.

Static libraries used in iPhone applications do not need to be code signed. Therefore, you should remove

the Code Signing Identity build setting definition from the static library targets you create. To do so:

1. Open the static library target’s Info window and display the Build pane.

2. In the Code Signing category, select the Any iPhone OS Device conditional definition for the Code Signing

Identity build setting.

3. Change the conditional definition’s value from iPhone Developer to Don’t Code Sign.

To learn more about the iPhone application architecture, see iPhone Application Programming Guide.

To develop an iPhone application, you work on an Xcode project. And you do most of your work on projects

through the project window, which displays and organizes your source files and other resources needed to

build your application. It allows you to access and edit all the pieces of your project. Figure 1-1 shows the

project window.
