when to call setNeedsStatusBarAppearanceUpdate if implementing prefersStatusBarHidden: method

The documentation on hiding status bar says that I should implement this method 

override prefersStatusBarHidden(){
    return true
}

and than it says: If you change the return value for this method, call the setNeedsStatusBarAppearanceUpdate method. When should I call this method, in viewDidLoad, in prefersStatusBarHidden or somewhere else?

In most cases you don't need to call setNeedsStatusBarAppearanceUpdate() at all. When your view controller appears or disappears iOS checks prefersStatusBarHidden() automatically.

You only need to call setNeedsStatusBarAppearanceUpdate() when the value returned by prefersStatusBarHidden() changes while your view controller is visible.
