Reflow mode in iOS app

We're using the PDF viewer to display multi-page PDFs in reflow mode (in an iOS app), and have encountered these problems.

1. when changing orientation (device rotation), how do we make the reflow view fit to the device screen?
2. when we scroll to the bottom of the current page, and then go to the next page, the next page will also show the bottom of the image too, is there a way to make the viewer scroll to the top of the image after page changes?

Appreciate your help and advice pls, thanks.

Hi,

you should try to add this method to RDPDFReflowViewController:

- (void)viewWillTransitionToSize:(CGSize)size withTransitionCoordinator:(id<UIViewControllerTransitionCoordinator>)coordinator
{
[m_view setFrame:CGRectMake(0, 0, size.width, size.height)];
[m_view render:m_cur_page:ratio];
}

Hi Emanuele,
Thank you, that seems to resolve the problem with the screen orientation change (1).
Can you advise on our 2nd problem (2) with getting the page to scroll to the top after a page change pls?
Cheers

Hi,

to fix your second issue you could edit prePage and nextPage methods, in RDPDFReflowViewController:
add something like [m_view scrollRectToVisible:CGRectMake(0, 0, 1, 1) animated:NO]; after [m_view render:m_cur_page:ratio]; and the view will scroll to top when the page changes.
