A
UIPageControl
is a row of dots giving sequential (not random) access to page numbers.
Allow 16 pixels (or 16 pairs of pixels on iPhone 4)
horizontally for each dot.
The
numberOfPages
and the
currentPage
are
NSIntegers,
probably the same as an
int.
The page numbers start at zero,
so we add 1 to them in
drawRect:
