I'm building an application with a tab bar at the bottom showing two different object types - for example, buildings and trucks.
Each of these tabs shows buildings and trucks in separate table views.
I want the user to be able to create a new building or a new truck.
I'm aware that it's common practice to hide the tab bar on a leaf view controller - but does this apply to the New Building/Truck screen too?
When I show a New Building/Truck screen, should I hide the tab bar or show it?
