Presenting View Controllers in iOS

The Present ViewController is a method in the UIViewController class used to display another view controller.

Specifically, when we call the Present ViewController method in a view controller A and pass another view controller B as a parameter, the system will display view controller B modally on top of view controller A.

There are multiple ways to present view controller B, such as popping up from the bottom, top, or sides with different animation effects. We can specify the presentation style and animation effect by passing different parameters when calling the Present ViewController method.

After the view controller B is presented, the view controller A will pause its execution and wait for the completion of view controller B before resuming its execution.

After displaying view controller B, we can perform various operations within it such as displaying or modifying data, responding to user interactions, etc.

When we need to dismiss view controller B and return to view controller A, we can call the Dismiss method in view controller B. The system will remove view controller B from on top of view controller A and reactivate view controller A.

By using the Present ViewController method, we can display new view controllers in the application, allowing for seamless switching and interaction between different views, enhancing the user experience.
