Unable to display printer options with AirPrint

Question

I want to add AirPrint functionality to my iPad application

I have been trying to display printer ontions described in Apple's Drawing and Printing Guide

I have toolbar and UIBarButtonItem *printButton. In controller I receive onPrintClick and try to display printer options by such code:

UIPrintInteractionController *controller = [UIPrintInteractionController sharedPrintController];
 [controller setDelegate:self];
 if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
  [controller presentFromBarButtonItem:self.printButton animated:YES
         completionHandler:completionHandler];
 } else {
  [controller presentAnimated:YES completionHandler:nil];
 }

Please help, because I do receive nothing :(

Answer 1

You need to set printItem/printItems property in order to use an AirPrint.

controller.printItem = a URL to PDF or image file;

There is this similar question: How to print in iOS 4.2?

Try with this. It really helped me in adding Air Print to my app.
