iPhone/iPad draw pdf like iBooks?

问题 Does anyone know how to use core graphics to draw a pdf like in iBooks. I can already draw a pdf page using core graphics but was curious how iBooks shows a lower quality view of each page so it loads fast and then when you stay on a page longer it renders it a full quality. This makes it able to open the pdf without having to make the user wait like most magazine apps you see on ipad. Any ideas would help! 回答1: Apple have some "ZoomingPDFViewer" sample code: http://developer.apple.com
