Hi Team,

I am having the same problem. Can you please let me know what could be the possible solution ?

When I zoom a page, it do not stand still on the same area. It moves to another location after zooming. It happens only when I set paging enable. In PDFView, I set self.pagingEnabled=YES. Otherwise zooming is good but I need zooming and paging both.

Please send a quick response.
Thanks

Hi,

you can try to disable pagingEnabled in scrollViewDidZoom method, and set it to YES at the end of scrollViewDidEndZooming method if self.zoomScale <= 1 (if entire page is shown).

If the page is not centered when you zoom out, you can also call vGoto.

in scrollViewDidEndZooming you should add something like:
Code:
if (self.zoomScale <= 1) { self.pagingEnabled = YES; [self vGoto:m_cur_page]; }
