Is there a way to programmatically scroll to a PDF page within a UIWebView?

Question

It is possible to use JavaScript to set the pixel y-offset of a UIWebView, e.g.:

[webView stringByEvaluatingJavaScriptFromString:[NSString strin         


        

Answer 1

The uiwebview commonly used to load pdf's has it's own scrollview object that you can make calls to. try something like this:

    [webview.scrollView setContentOffset:CGPointMake(0, webview.scrollView.contentOffset.y + 100) animated:YES];    

This will scroll the view for the pdf down 100 pixels. As for getting the pagenumber of the pdf, I can only imagine that javascript is what you need to take a look at. Or, If you simply know the number of pixels on each page of the pdf, then increment or decrement as necessary. :)
