sorry, some methods seems not implement on ios.
this method shall be easy, plz add following codes to class PDFLayoutView

-(void)vGotoPage:(int)pageno
{
    if(!m_layout) return;
    RDVPage *vp = [m_layout vGetPage:pageno];
    if(!vp) return;
    self.contentOffset = CGPointMake([vp GetX]/m_scale_pix, [vp GetY]/m_scale_pix);
    //[self scrollRectToVisible:CGRectMake([vp GetX]/m_scale_pix, [vp GetY]/m_scale_pix,
    //  [vp GetWidth]/m_scale_pix, [vp GetHeight]/m_scale_pix) animated:YES];
}

and then, in your ViewController, you shall invoke [PDFLayoutView vGotoPage:pageno];
this method not tested, we shall test on next days.

[self PDFGoto:page]; PDFGoto calls vGoto method of PDFLayoutView.
