Navigation Bars - Bars - iOS - Human Interface Guidelines - Apple Developer
A navigation bar 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.
