Populating the Toolbar

Now that you have the icons, it is time to add a toolbar to the add/view car screen. An important thing to remember is where you add the toolbar. You can always drag a UIToolbar into any view controller. But for toolbars that could be project wide, you set them up in the navigation controller. Here’s how you do this:

1. Open the iPhone storyboard and select the Navigation Controller.

2. In the Attributes inspector, change Bottom Bar from Inferred to Opaque Toolbar. A toolbar appears at the bottom of the controller as well as of every scene on the storyboard.

3. Select the add/view car scene and drag three UIBarButtonItems into the toolbar. Then drag in a flexible space item between each pair of buttons. Figure 7-7 shows adding the second flexible space.
