Exercise: Pollock Plus One
In the next exercise, we take the existing Pollock app (from Chapter 6, “Working with Lists”) and add a second screen. This gives you practice in creating multiple screens and ensuring that you have a path for navigating between the two.
1. Launch Pollock from the My Project page. On the Designer screen, add another button next to the row of buttons devoted to the paint colors.
2. Rename the button to Switch in the components table. Be sure to also change the text for the button in the Properties box. Give it a different color, such as Cyan (see Figure 8.12).
