1. Window: uiwindow

The iPhone rule is a window with multiple views. The window is the bottom layer that you see in the app. It is fixed and can be ignored basically, but you need to know the architecture of each layer.

2. View: uiview

Uiview is the basis for the user to build the interface. All the controls are drawn on this page. You can regard them as a canvas. You can add controls through uiview, and use controls to interact with users and transmit data.

Windows and views are the most basic classes and are used to create user interfaces of any type. A window represents a geometric area on the screen, while the View class draws different controls with its own functions, such as navigation bar and buttons are attached to the View class, A view is linked to a window.

3. View Controller: uiviewcontroller

View Controller uiviewcontroller. You can manage and control the uiview you want to use. You can control the specific uiview you want to display in this uiviewcontroller. In addition, the View Controller adds additional functions, such as built-in rotation screens, transition animations, and support for touch and other events.

4. Introduction to uikit

today, we will briefly introduce some commonly used controls for iOS application development, as well as the basic uiview, the relationship between uiwindow and uiviewcontrol is the foundation, which directly affects future development capabilities. Next I will talk about these controls separately. This is the end of today. Thank you ~.
