Instance Method

viewDidLayoutSubviews()

Called to notify the view controller that its view has just laid out its subviews.

Declaration

func viewDidLayoutSubviews()

Discussion

When the bounds change for a view controller'€™s view, the view adjusts the positions of its subviews and then the system calls this method. However, this method being called does not indicate that the individual layouts of the view'€™s subviews have been adjusted. Each subview is responsible for adjusting its own layout.

Your view controller can override this method to make changes after the view lays out its subviews. The default implementation of this method does nothing.
