const char *password = [pwd UTF8String];
m_doce = Document_open(cpath, password, &err);
if( m_doce == NULL )
{
switch( err )
{
case err_password:
return 2;
break;
default: return 0;
}
}
CGRect rect = [[UIScreen mainScreen]bounds];
float hi = self.navigationController.navigationBar.bounds.size.height;
m_view = [[PDFView alloc] initWithFrame:CGRectMake(0, 0, rect.size.width, rect.size.height-20-hi)];

Hi,

try to init m_doc in this way:

PDF_ERR err = 0;
m_doc = [[PDFDoc alloc] init];
err = [m_doc open:path :pwd];

instead of:

m_doce = Document_open(cpath, password, &err);
