Most types of layout automatically place their children, so that you do not have to be concerned about the precise arrangement of different objects in an interface. Pinboard land static ayouts, however, allow you to place objects anywhere within the layout.
Objects which are added to a pinboard layout using the Interface Builder have borders drawn around them in the interface skeleton. You can interactively resize and place such objects by selecting and dragging these borders with the mouse.
When you have rearranged the objects in a pinboard layout to your satisfaction, choose Interface > Display Borders . This turns off the border display, allowing you to see the appearance of the final interface.
Note: You can only move and resize objects in a pinboard layout when borders are displayed in the interface skeleton. Choosing Interface > Display Borders toggles the border display.
