Part I: Planning Your iPhone Software Product
This part of iPhone Human Interface Guidelines describes ways to think about designing and developing software for iPhone OS. Read the chapters in Part I to learn about the different types of software you can develop for iPhone OS and the design principles you can use to inform your work. You’ll also learn how to apply those principles to specific aspects and tasks in your application, so you can create a superlative product that provides an intuitive and compelling user interface.
iPhone 人机界面设计规范的这个部分描述了设计和开发iPhone OS软件的方法。通过这个部分的阅读，你将了解到可以为iphone OS创建的软件类型以及你可以在工作中应用的设计准则。 同时你将得知如何在软件的各个方面细化的应用这些准则，从而开发出具有漂亮易用界面的杰出产品。
第二部分：为你的 iPhone 软件设计用户界面
Part II: Designing the User Interface of Your iPhone Application
User interface elements in iPhone OS include views and controls. Views provide content regions with well-defined sets of functionality. Controls are graphic objects that cause instant actions or visible results. Although all an application’s views and controls are contained in the application’s single window, users see and interact with them in screens, which roughly correspond to different visual states in the application.
iPhone OS 的用户界面元素包括视图和控件。视图为内容提供定义良好的功能集。控件是引起即时行动或可视结果的图形对象。尽管所有的视图和控件都包含于应用程序窗口，用户在屏幕上察看它们并且与它们交互，这些屏幕大致对应于应用程序不同的视觉状态。
iPhone OS defines the standard appearance of these user interface elements, and delivers consistent behaviors that users expect. Read the chapters in Part II to learn about the types of user interface elements available and how to use them to build the user interface of your application.
