Buttons 3-13
Avoid spacing consecutive buttons so close together that they look cramped.
On an Apple MessagePad, space consecutive buttons in a group three pixels
apart, and leave four pixels between buttons and the view’s border. If you
must, you can reduce the space between consecutive buttons to two pixels,
but no less. Figure 3-13 illustrates the MessagePad guidelines.

If your application changes a button’s name, it should dynamically resize the
button and maintain the correct spacing between buttons. Your application
should maintain the correct spacing between buttons when a user rotates the
display (with the Extras Drawer). Accommodate the changing width of a
view by adding or taking away space between groups of buttons. Your
application also needs to maintain the spacing between buttons if their
names change during operation.
