用于工具栏与导航栏的标准按钮
Standard Buttons for Use in Toolbars and Navigation Bars
iPhone OS makes many of the standard buttons users see in toolbars and navigation bars available to you. These buttons, shown in Table 10-1, are available in two styles, each of which is appropriate for the specific usages described here:
iPhone OS 为你准备了用户能够在工具栏和导航栏上看到的大量标准按钮。表 10-1 所示的这些按钮具有两种样式，分别用于下列不同的情况：
- Bordered style—for example, the Add button in the Phone Contacts navigation bar. This style is suitable for both navigation bars and toolbars.
- 带边框样式——例如，在电话联系人导航栏上的“添加”按钮。该样式同时适用于导航栏和工具栏。
- Plain style—for example, the Compose button in the Mail toolbar. This style is suitable for toolbars only. In fact, if you specify the plain style for a button in the navigation bar, it will be converted to the bordered style.
- 平面样式——例如，Mail 工具栏上的“撰写”按钮。该样式仅适用于工具栏。事实上，如果你为导航栏上的按钮指定平面样式，它会转换成带边框样式。
As with all system-provided buttons, you should avoid using the buttons described in Table 10-1 to represent actions other than those for which they are designed. In particular, avoid choosing a button based on its appearance, without regard for its documented meaning. See “Using System-Provided Buttons and Icons” for a discussion of the reasons why it’s important to use these icons correctly. (Information on symbol names and availability for these buttons is available in documentation for UIBarButtonSystemItem.)
对于所有系统自带的按钮，你应当避免将表 10-1 中的按钮用于表示其设计用途之外的操作。尤其要根据其文档中描述的含义来选择按钮，而非其外观。关于正确使用这些图标的原因的讨论，参见“使用系统自带的按钮与图标”。（关于这些按钮符号名称和可用状态可参阅 UIBarButtonSystemItem 的文档。）

In addition to the buttons shown in Table 10-1, you can also use the system-provided Edit, Cancel, Save, and Done buttons shown in Table 10-2 to support editing or other types of content manipulation in your application. (Information on symbol names and availability for these buttons is available in documentation for UIBarButtonSystemItem.) These buttons are suitable for both navigation bars and toolbars, and are available in the bordered style only. If you specify the plain style for one of these buttons, it will be converted to the bordered style.
除了表 10-1 中列出的按钮之外，你还可以使用系统自带的编辑、取消、保存和完成按钮以便在你的应用程序中支持编辑或其他类型的内容处理，如表 10-2 所示。（关于这些按钮符号名称和可用状态可参阅 UIBarButtonSystemItem 的文档。）这些按钮在导航栏和工具栏上都可使用，但仅具有带边框样式。如果你为这些按钮指定平面样式，它会转换成带边框样式。
