If all you want to do is display a PDF, just use a UIWebView. It will
display the PDF just like Safari with scrolling and whatnot and handle
everything for you.

Hi,
I'm new to both Cocoa and iPhone so perhaps I've taken on
something too complicated for a beginner, but I'm trying to display
a PDF in a UIScrollView so that I can zoom/drag, etc. I've created a
view hierarchy with a main UIView (probably should be a
UIViewController, but that's another conversation) that has 3
subviews, a UIScrollView and 2 other UIView objects used to hold
custom controls. I've created a PDFView as a subclass of UIView and
add it as a subview of the UIScrollView. The actual drawing of the
PDF is done in the drawRect method of my PDFView object using the
Quartz 2D PDF drawing calls. The zooming and dragging work, however,
when I scroll the view it drags too far, exposing the background of
my view. I had assumed that setting the contentSize of the
UIScrollView to the size of the zoomed PDF would prevent the PDFView
from moving away from the edge of the view, but I'm apparently
missing something.
Can someone point me to some sample code that illustrates the
proper technique for drawing a PDF inside a scroller or perhaps
offer some suggestions on what I might be overlooking?
