View is not opening

I integrated new SDK in iOS. There is no error.
[self.view addSubview:m_view];
It returns 1 in RDPDFViewController.
In MainviewController.m
// method - (void)openPDF:(id)sender
if(result == 1)
{
m_pdf.hidesBottomBarWhenPushed = YES;
[self.navigationController pushViewController:m_pdf animated:YES];
}
It is not opening. It simply blinks . View s not coming.
Help me to solve the issue. Thanks in advance.

Hi,imran.nazeer

Is m_view define as PDFView?

Try open a file like below:
result = [m_pdf PDFOpen:pdfFullPath :pwd];
if(result == 1)
{
UINavigationController *nav = self.navigationController;
m_pdf.hidesBottomBarWhenPushed = YES;
nav.hidesBottomBarWhenPushed =NO;
[nav pushViewController:m_pdf animated:YES];
}

It needn't add a subView , just push the RDPDFReflowViewController , the file will show.
p.s pwd is password of PDF file , if no password ,define it as @"" or nil

Do we need to add RDPDFReflowViewController.
In the Documentation, it wasnt given

www.androidpdf.mobi/download/download-io...69-ios-pdfviewer-210
here can download new version demo. Did you use this version？

Yes am using that version only

Still the same issue even after pushing to RDPDFReflowViewController.
Its not opening
