Adding Buttons in Interface Builder

Buttons appear in the Interface Builder library as Rounded Rect Button objects. To use them, drag them into your interface. You can then change them to another button type via the attribute inspector (View > Utility > Show Attributes Inspector, Command-Option-4). A button-type pop-up appears at the top of the inspector, as shown in Figure 9-3. Use this pop-up menu to select the button type.

Figure 9-3. Choose your button type from the Type pop-up in the attributes inspector (left). Changes in the Button section apply to the current configuration (right).

If your button uses text (such as the word “Button” in Figure 9-2), you can enter that text in the Title field. The Image and Background pull-downs let you choose a primary and background image for the button.
