iPhone : App crashes while displaying print option from UIButton

In my app I am displaying Print option from UIButton using following code.

    UIPrintInfo* printInfo = [UIPrintInfo printInfo];
    printInfo.outputType = UIPrintInfoOutputGeneral;
    printInfo.jobName = NSLocalizedString(@"Offerings", @"");


    UIMarkupTextPrintFormatter *formatter = [[UIMarkupTextPrintFormatter alloc] initWithMarkupText:@"Share"];
    formatter.startPage = 0;


    CGFloat margin = 72.0f * 0.1f;
    formatter.contentInsets = UIEdgeInsetsMake(margin, margin, margin, margin);


    UIPrintInteractionController* pic = [UIPrintInteractionController sharedPrintController];
    pic.delegate = self;
    pic.showsPageRange = YES;
    pic.printInfo = printInfo;
    pic.printFormatter = formatter;
    [formatter release];

    void (^completionHandler)(UIPrintInteractionController*, BOOL, NSError*) = ^(UIPrintInteractionController* printController, BOOL completed, NSError* error)
    {
        if (!completed && error)
        {
            UIAlertView* alert = [[UIAlertView alloc]
                                  initWithTitle:NSLocalizedString(@"Printing Error", @"")
                                  message:[error localizedDescription]
                                  delegate:nil
                                  cancelButtonTitle:@"OK"
                                  otherButtonTitles:nil];

            [alert show];
            [alert release];
        }
    };

I have tried following options.

    [pic presentAnimated:YES completionHandler:completionHandler];

OR

    [pic presentFromRect:CGRectMake(btnPrint.frame.origin.x, btnPrint.frame.origin.y, btnPrint.frame.size.width, btnPrint.frame.size.height) inView:self.view animated:YES completionHandler:comple开发者_JAVA百科tionHandler];

But it crashes with error : EXE_BAD_ACCESS

But when I tried following code for displaying print option, It works fine.

  [pic presentFromBarButtonItem:self.navigationItem.rightBarButtonItem animated:YES completionHandler:completionHandler];

Now, I am not using navigation controller. So I can't use this above method.

What should I do ?

Why can't you use: [self presentViewController: animated: completion:];?

Ok. I have solved my problem.

The view where you are going to give print option. It should be contain navigation controller.

So, My solution

First *first = [[First alloc] initWithNibName:@"First"];
UINavigationController *nav = [[UINavigationController alloc] initWithRootView:@"first"];
[self presentViewController:nav animated:YES];

Its strange solution. but worked for me.
