iPhone UIWebView PDF Page Jump
I want to view a local PDF (in my iPhone app) and be able to jump to a specific page. Seems like the UIWeb开发者_JAVA技巧View is the way to go, however, I can't find any information on jumping to specific pages. Is this impossible? Are there any other techniques I can use?
thanks, Howie
You can try using Javascript. See this link for more details. You'll want to use something along the lines of @"window.scrollTo(0, x);"
, where x is some value you determined by playing around with the WebView.
Another option would be to set the content offset of the UIWebView like Mike pointed out (but without involving JavaScript):
webView.ScrollView.SetContentOffset(new PointF(0, y), true);
(sorry for the MonoTouch code but ObjectiveC is still on my todo list)
Alternatively to an UIWebView, you can use the Quartz API :http://developer.apple.com/iphone/library/documentation/GraphicsImaging/Conceptual/drawingwithquartz2d/dq_pdf/dq_pdf.html
It's more complicated, but you should be able to do whatever you want.
