    NSMutableData *pdfData = [NSMutableData data];
    CGRect oldFrame = aView.frame;
    [aView sizeToFit];
     CGRect rect = CGRectMake(aView.scrollView.contentOffset.x, aView.scrollView.contentOffset.y, fullSize.width, fullSize.height);
    // Points the pdf converter to the mutable data object and to the UIView to be converted
    UIGraphicsBeginPDFContextToData(pdfData, self.pdfView.scrollView.bounds, nil);

    UIGraphicsBeginPDFPage();
    CGContextRef pdfContext = UIGraphicsGetCurrentContext();
    [self.pdfView.scrollView.layer renderInContext:pdfContext];
    // remove PDF rendering context
    UIGraphicsEndPDFContext();

    [pdfData writeToFile:getPdfpath atomically:YES];

You can use something like this to load the PDF into an NSData object:

NSData *pdfFile = [NSData dataWithContentsOfURL:webView.request.URL];

Then, you can use the NSData methods to write the data to a file:

[pdfFile writeToFile:filePath atomically:YES];

Of course, you'll need to setup filePath to be an appropriate writable location to store the file/

  • Thanks for your answer. Yes its working i want to write UIWebview.scrollView. Because i have added some image in UIWebview scrollview subview . its possible ? – 2vision2 Jan 06 '15 at 11:51
  • Hm -- you may need to start a new question with this, since the edited version is almost completely different than what I answered, but I can try to help. Are you saying you need to export a UIWebView with a PDF that's been loaded, plus the changes you made by adding/removing UIViews? – jnpdx Jan 06 '15 at 19:32
  • You can write a PDF of the view (bitmapped) by using this technique: http://stackoverflow.com/questions/5443166/how-to-convert-uiview-to-pdf-within-ios – jnpdx Jan 06 '15 at 20:20

If you need to call and access any file then first of all you need to add that file in your project after that you can use the below code to access it.

 NSString* path = [[NSBundle mainBundle] pathForResource:@"Terms"
                                                         ofType:@"txt"];
   NSString *content = [NSString stringWithContentsOfFile:path
                                                      encoding:NSUTF8StringEncoding
                                                         error:NULL];
