A navigation ios navigation bar height custom appears at the top of an app screen, below the status bar, and enables navigation through a series of hierarchical screens.

When a new screen is displayed, a back button, often labeled with the title of the previous screen, appears on the left side of the bar. Sometimes, the right side of a navigation bar contains a control, like an Edit or a Done button, for managing the content within the active view. In a split view, a navigation bar may appear in a single pane of the split view. Navigation bars are translucent, may have a background tint, and can be configured to hide when the keyboard is onscreen, a gesture occurs, or a view resizes.

Consider temporarily hiding the navigation bar when displaying full-screen content. The navigation bar can be distracting when you want to focus on content. Temporarily hide the bar to provide a more immersive experience. Photos hides the navigation bar and other interface elements when viewing full-screen photos, ios navigation bar height custom. If you implement this type of behavior, let people restore the navigation bar with a simple gesture, like a tap.

For developer guidance, see Ios navigation bar height custom. See Toolbars. Consider showing the title of the current view in the navigation bar. However, if titling a navigation bar seems redundant, ios navigation bar height custom, you can leave the title empty.

Use a large title when you want to provide extra emphasis on context. Large titles should never compete with content, but in some apps, the big, bold text of a large title can help orient people as they browse and search. In a tabbed layout, for example, large titles can help clarify the active tab and indicate when people have scrolled to the top.

Phone uses this approach, while Music uses ios navigation bar height custom titles to differentiate content areas like albums, artists, playlists, and radio. Also, a large title transitions to a standard title as people begin scrolling the content, ios navigation bar height custom.

Avoid crowding a navigation bar with too many controls. Use the standard back button. People know that the standard back button lets them retrace steps through a hierarchy of information.

However, if you implement a custom back button, make sure it still looks like a back button, behaves intuitively, matches the rest of your interface, and is consistently implemented throughout your app. If you replace the system-provided back button chevron with a custom image, supply a custom mask image too. The back button always performs a single action—returning to the previous screen.

Give text-titled buttons enough room. If your navigation bar includes multiple text buttons, the text of those buttons may appear to run together, making the buttons indistinguishable. Add separation by inserting a fixed space item between the buttons. Consider using a segmented control in a navigation bar to flatten your app's information hierarchy.

If you use a segmented control in a navigation bar, do so only at the top level of your hierarchy and be sure to choose accurate back-button titles at lower levels.

For additional guidance, see Segmented Controls. Navigation Bars A navigation bar appears at the top of an app screen, below the status bar, and enables navigation through a series of hierarchical screens.
