在应用程序界面中使用视图和控件

Using Views and Controls in Application Screens

In iPhone OS, UIKit determines the behavior and default appearance of views and controls. As much as possible, you should use the standard user interface elements UIKit provides and follow their recommended usages. Doing this helps you in two important ways:

在iPhone OS中，视图和控件的默认外观和行为方式是由UIkit所决定的。你应该尽可能多的应用这些UIkit中的标准用户界面元素，并准照它们的习惯用法。这样做将会给你带来如下两种好处：

• Users are accustomed to the look and behavior of standard views and controls. When you use familiar user interface elements, users can depend on their prior experience to help them as they learn to use your application.

用户已经习惯了那些标准视图和控件的外观和行为方式。当他们第一次使用的时候，他们就可以根据自己以往的经验，来帮助他们学习使用新的应用程序。

• If iPhone OS changes the look or behavior of standard views or controls, your application continues to work and automatically looks up to date with little, if any, work on your part.

如果iphone OS 更新原本标准视图和控件的外观和行为方式，你只需要花很少的时间就能对应至新的标准。

Many controls support some kind of customization, usually in color or content (such as the addition of a text label or an image). If you’re developing an immersive application, it’s reasonable to create controls that are completely different from the default controls. This is because you’re creating a unique environment, and discovering how to control that environment is an experience users expect in immersive applications.

很多控件都在颜色和内容方面支持一定程度的自定义（如添加文字标签或图片）。如果你是在开发一个immersive应用程序，采用与默认控件完全不同风格的新控件是完全可行的。这是因为对于immersive应用程序而言，需要的是一个专家级用户能够发现并掌控整个系统的特殊环境。

In general, though, you should avoid radically changing the appearance of a control that performs a standard action. If you use unfamiliar controls to perform standard actions, users will have to spend time discovering how to use them and will wonder what, if anything, your controls do that the standard ones do not.

总的说来，你需要尽量避免过多的更改那些控件的标准外观和用法。如果你使用用户所不熟悉的空间，那么用户就要花费更多的时间来学习如何使用他，并且尝试着去挖掘你的控件在功能上是否和标准控件有所不同。
