Called when the view controller’s view is about to be removed from the view hierarchy in the window.
- macOS 10.10+
You can override this method to perform tasks that are to precede the disappearance of the view controller’s view, such as stopping a continuous animation that you started in response to the
view method call. This method is called when:
The view is about to be removed from the view hierarchy of the window
The view is about to be hidden or obscured, such as in the case of a view controller whose parent is a tab view controller and the user switched to another tab
The window is being closed
If you override this method, call this method on
super at some point in your implementation in case a superclass also overrides this method.
The default implementation of this method does nothing.
