What is ViewController Lifecycle?
The ViewController lifecycle in iOS refers to the sequence of methods called as a view controller transitions between states. It begins with initialization, followed by loading the view, appearing on screen, disappearing, and potentially being deallocated. Key methods include viewDidLoad(), viewWillAppear(), viewDidAppear(), viewWillDisappear(), and viewDidDisappear(). Understanding this lifecycle is crucial for managing resources, updating UI, and handling state changes efficiently in iOS apps.
