Tab Bars - Bars - iOS - Human Interface Guidelines - Apple Developer
A tab bar appears at the bottom of a screen, helping people understand the types of information or functionality an app provides.
Tabs let people quickly switch between top-level sections in your app while preserving the current navigation state within each section.
⇒ 화면 아래에 위치
⇒ 앱 최상위 섹션에 빨리 전환 가능, 다른 섹션의 내비게이션 상태 유지한 상태로
By default, a tab bar is translucent:
It uses a background material only when content appears behind it, removing the material when the view scrolls to the bottom.
A tab bar hides when a keyboard is onscreen.
⇒ 디폴트로 반투명
⇒ 배경은 스크롤해서 맨 밑으로 가면 없어짐
⇒ 키보드 있으면 숨음
Use a tab bar only to enable navigation, not to help people perform actions.
⇒ 역할 = 화면 이동
⇒ control 아님(하려면 tool bar 사용)
Use the minimum number of tabs required to clarify your information hierarchy and help people navigate your app.
Avoid hiding the tab bar when people navigate to different areas in your app.
