Screens

​

Overview

Screens are made up of components, a ScreenSettings for that screen, and a ViewModel that provides the screen’s functionality. Each screen has custom user interface components. Each screen has a specific ScreenSettings that creates the view and each ScreenSettings contains customizable UI components. A screen also has a corresponding ViewModel that provides the necessary data from QuickBlox iOS SDK. Refer to the table below to see which screens we provide and the components that make up each screen.
