It always appears at the upper edge of the device screen and contains user expected information such as the date and time of day, network connection, and battery charge. Several color patterns can be used to display status bar.


It enables navigation by following a specific set of data hierarchy, and also manages content displayed on the screen. It is contained in a navigation controller and succeeds the ladder of custom views. Navigation bar is displayed just below the status bar. It usually displays the title of the current screen. Users tap the back button to return back to previous screen by navigating through a hierarchy of data information. Every control in a navigation bar contains a bezel around them, which is defined as the style of border by iOS. If any borderless control is placed in a navigation bar then it automatically converts to the bordered style.


A toolbar consists of controls that perform actions related to objects in the screen/view. On iPhone, a toolbar always appear at the bottom edge of the screen. Toolbar items are displayed equally spaced across the width of the toolbar. When the iPhone user changes the device orientation from landscape to portrait; or wise versa, then automatically the height of toolbar is changed.

Tab bar doesn’t have the ability to display more than five tabs at one time. If any iPhone apps have more tabs, then the tab bar displays only four out of the N number of tabs and adds the rest of them under “moretab”. The more tab shows the additional tabs in a list. A tab bar does not change its height in any size device. It is not device orientated.
