CHAPTER 2
Container Views
How Views Work 2-41
Local scroll arrows can use color—white or black—to indicate whether
scrolling will bring more items or any more empty space into view. An arrow
is black if tapping it will bring more items into view. An arrow is white if
tapping it will not bring more items into view. Figure 2-33 illustrates the use
of color in local scroll arrows.
Figure 2-33 Scroll arrow color may indicate what scrolling will reveal
If you implement local scrolling in your application and want users to easily
recognize your local scroll arrows, make them look like the arrows in the
built-in applications. Do not design your own scroll arrows or make them look
like scroll arrows on personal computers.
Four-way Scrolling 2
A view that allows the user to pan up, down, left, and right across a map,
drawing, or other large document must provide a four-way (two-dimension)
scrolling control. The four-way scroller should be centered at the bottom of
the view. Figure 2-34 shows how the standard four-way scroller looks.
White—empty in this direction
Black—more items in this direction
