How to show the downloaded pdf with CGPDFDocumentRef?

Question

I am downloading pdf file from server using this code.

   NSString *urlString = @"https://developer.apple.com/library/ios/documentation/uikit/reference/UILabel_Class/UILabel_Class.pdf";

   NSURL *url = [NSURL URLWithString:urlString];

   ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
   [request setDownloadDestinationPath:[[NSHomeDirectory() stringByAppendingPathComponent:@"Documents"] stringByAppendingPathComponent:@"UILabel.pdf"]];
   [request setDelegate:self]; 
   [request startAsynchronous];

Download functionality is working fine. But i need to show the downloaded pdf with CGPDFDocumentRef.

Thanks in advance.

After downloading your pdf save that pdf file into document directory and from there retrive your pdf and display using CGDocumentref as below:

  CFURLRef pdfURL = (CFURLRef)[[NSURL alloc] initFileURLWithPath:[documentsDirectory stringByAppendingPathComponent:source]];
        //file ref
        CGPDFDocumentRef pdfRef = CGPDFDocumentCreateWithURL((CFURLRef) pdfURL);
