OK, you can use [PDFV vGetDeltaToCenterPage:pageno:&m_swipe_dx:&m_swipe_dy] to center pages.
if you don't want dual page mode, then alloc boolean array, and set all elements to false.
then invoke:
[[PDFVDual alloc] init:false :NULL :0 :horzs :0];
when open document.
in this way, all pages are layouted as single pages.

for scale value:
you can invoke [PDFV vSetScale:0] to zoom back to min-scale.

    //defView =2;
    bool *verts = (bool *)calloc( sizeof(bool), Document_getPageCount(doc) );
    switch(defView)
    {
        case 1:
            m_view = [[PDFVHorz alloc] init:false];

            m_view = [[PDFVHorz alloc] init:true];
            break;
        case 3:
            //for dual view
            //m_view = [[PDFVDual alloc] init:false :NULL :0 :NULL :0];
            //for single view
            m_view = [[PDFVDual alloc] init:false :NULL :0 :verts :Document_getPageCount(doc)];
