Question

So, I am well aware that when the back button is pressed in classes embedded in UINavigationControllers, the previous view’s viewDidAppear() method is called. However, I need the viewDidLoad() method to be called, much like it is with a push segue into a scene. Is there a possible way to do this? Maybe by modifying the method that is called when the back button is pressed? What is the method that is called when the back button is pressed? Thanks.

Answer 1

Firstly viewWillAppear and then viewDidAppear is getting called on push back. And for lazy loading of views, it is preferable to add/operate UI subviews in viewWillAppear, and make them set view to nil in viewDidDisappear for memory management.
