iOS view controller

Open the library by clicking the plus button (+) at the top-right of the Xcode window, and then drag a Text view to the place in your code immediately below the “Turtle Rock” text view.

A view controller has two parts: the designed part that’s in Storyboard and a Swift file that contains the code for that screen . If a screen in the application doesn’t require any code, then it can use the default UIViewController .

If you are not familiar with the code and you want to find ViewController coresponding to given view, then you can try:

Right-click the control or object in your current view controller. Drag the cursor to the view controller you want to present. Select the kind of segue you want from the list that Xcode provides.

UIView can be defined as an object by using which we can create and manage the rectangular area on the screen . We can have any number of views inside a view to create a hierarchical structure of the UIViews. The UIView is managed by using the methods and properties defined in the UIView class that inherits UIKit.

Views are the fundamental building blocks of your app’s user interface , and the UIView class defines the behaviors that are common to all views. A view object renders content within its bounds rectangle, and handles any interactions with that content.

In iOS development, the view controllers are the foundation of the Application’s internal structure . The View Controller is the parent of all the views present on a storyboard. Each application has at least one ViewController. It facilitates the transition between various parts of the user interface.
