When it is attached to a tab bar controller, the tab bar item represents the view controller. It is a tab bar item by taping a new view over the tab bar. This is the tab bar item. The UITabBarItem class example, which inherits UIBarItem, is a tab bar item.
In the tab bar interface, a TabBarItem is used. A tab bar is operated in the radio mode where the user cannot simultaneously choose two-tab bar items. Using the UITabBarItem class attributes, we can configure the appearance of a table bar item. The badge for an item used for practically all iOS applications can also be specified. The badge value is used to display some vital data about the current view controller status. For instance, a message tab shows the number of new messages received with the badge on the Facebook program.
There is limited room for showing custom tab bar items in the TabBar linked with the tab bar controller. If we add more than four items to the tab bar, only the first four items are included, and additional items can be displayed in the tab bar. The more stuff you can choose from the usual interface.
