Hiding a UINavigationController's UIToolbar during viewWillDisappear:

Question

Managing the toolbar state (i.e. which VC needs/doesn't need the toolbar) gets tricky quickly.

I've had success with following this rule:

For each view controller, in viewWillAppear(), decide if it needs a toolbar or doesn't, then call navigationController?.setToolbarHidden(true or false, animated: animated) respectively.

This way, each view controller starts out with the correct toolbar state and you don't have to worry about "restoring" the toolbar state when the view controller is dismissed.
