Why do I need a tab bar on my iPhone?
A tab bar enables global navigation for your app, so it should remain visible everywhere. The exception to this is in modal views. Because a modal view gives people a separate experience that they dismiss when they’re finished, it’s not part of the overall navigation of your app. Don’t remove or disable a tab when its function is unavailable.
What’s the difference between tab bar and tab bar?
In general, use a tab bar to organize information at the app level. A tab bar is a good way to flatten your information hierarchy and provide access to several peer information categories or modes at once. Use a tab bar strictly for navigation. Tab bar buttons should not be used to perform actions.
What happens if you remove a tab from an app?
Don’t remove or disable a tab when its function is unavailable. If tabs are available in some cases but not in others, your app’s interface becomes unstable and unpredictable. Ensure that all tabs are always enabled, and explain why a tab’s content is unavailable.

How are tabs displayed on a tab bar?
