信息按钮

Info Buttons

An Info button provides a way to reveal configuration details about an application, often on the back of the screen. For this reason, Info buttons are especially well suited to utility applications. You can see an example of an Info button in the lower-right corner of the Weather application (shown in Figure 9-4).

一个信息按钮提供了一种用于揭示一个应用程序配置的详细信息的方法，often on the back of the screen。为此，信息按钮特别适用于utility applications。在天气应用程序的右下角你可以看到一个信息按钮的例子（如图9-4所示）。

Info buttons are available with a light background and a dark background. The light background style (which is shown in Figure 9-4) looks good on a view with a dark background. Conversely, an Info button with a dark background shows up well on a view with a light background.

信息按钮可与浅色背景和深色背景搭配。浅色背景风格（见图9-4）用在深色背景的应用程序上较好。相反，一个深色背景信息按钮更适合应用在浅色背景的应用程序上。

An Info button glows briefly when users tap it. When you use the Info button iPhone OS provides, you get this pressed-state appearance automatically.

一个简单信息按钮在用户点击它时会发光。当你使用iPhone操作系统提供的信息按钮时，此按下状态就会自动出现。
