Navigation Bars, Tab Bars, Toolbars, and the Status Bar
The status bar, navigation bar, tab bar, and toolbar are UI elements that have specifically defined appearances and behaviors in iOS applications. These bars are not required to be present in every application (apps that provide an immersive experience often don’t display any of them), but if they are present, it’s important to use them correctly. The bars provide familiar anchors to users of iOS-based devices, who are accustomed to the information they display and the types of functions they perform.
在 iOS 应用程序中，导航栏、标签栏、工具栏和状态栏这些 UI 元素的外观和行为方式都有着明确的定义。它们并非每个 iOS 应用程序都需要（提供沉浸式体验的应用程序通常不会使用这些 UI 元素），但一旦它们在你的程序中出现，就应当确保正确使用，这一点非常重要。使用 iOS 设备的用户已经熟知这些 UI 元素所呈现的信息以及它们的功能，这能够帮助用户建立起环境的熟悉感。
