We have submitted the iOS version, and we are getting crash reports on daily basis for this code in PDFVPage.m
-(void)Render
{
if( m_status == 2 ) return;
if( !m_page )
m_page = [m_doc page:m_pageno]; // this is line 79 . most crashes in this line <
if( m_dib == 0 )
{
PDFDIB *dib = [[PDFDIB alloc] init:m_dibw: m_dibh];
[m_page renderPrepare:dib];
m_dib = dib;
}
else
[m_page renderPrepare:m_dib];
if( m_status == 2 ) return;
PDFMatrix *mat = [[PDFMatrix alloc] init:m_scale: -m_scale: 0: m_dibh];
[m_page render:m_dib :mat :renderQuality]; // this is line 90 . some crashes on this line <
[self RenderFinish];
}
Here are example crash reports:
