iOS - Getting warning and not able to print

I'm using iOS 5.0.1 to develop an app. I'm using the following code to print the screen shot of the view in my ipad app:

CGRect rect = CGRectMake(0, 0, 768, 1004);
UIGraphicsBeginImageContext(rect.size);
CGContextRef context = UIGraphicsGetCurrentContext();
[self.view.layer renderInContext:context];
UIImage *img = UIGraphicsGetImageFromCurrentImageContext();       
UIGraphicsEndImageContext();

UIPrintInteractionController* pic = [UIPrintInteractionController sharedPrintController];
NSData *imageData = [NSData dataWithData:UIImagePNGRepresentation(img)];
if (pic && [UIPrintInteractionController canPrintData:imageData])
    {
        pic.delegate = self;
        UIPrintInfo* printInfo = [UIPrintInfo printInfo];
        printInfo.outputType = UIPrintInfoOutputPhoto;
        printInfo.jobName = @"PrintingImage";
        printInfo.duplex = UIPrintInfoDuplexLongEdge;
        pic.printInfo = printInfo;
        pic.showsPageRange = YES;
        pic.printingItem = imageData;

        void (^completionHandler) (UIPrintInteractionController *, BOOL, NSError*) = ^(UIPrintInteractionController *pic, BOOL completed, NSError* error) {
            if (!completed && error) {
                NSLog(@"Error: %@", error.localizedDescription);
            }  
        };

        [pic presentAnimated:YES completionHandler:completionHandler];
    }

Its not showing the printing view and throwing following error:

WARNING: Calling -[UIPrintInteractionController presentAnimated:completionHandler:] on iPad

I solved the issue by using following methods related to ipad

- (BOOL)presentFromRect:(CGRect)rect inView:(UIView *)view animated:(BOOL)animated completionHandler:(UIPrintInteractionCompletionHandler)completion;    // iPad
- (BOOL)presentFromBarButtonItem:(UIBarButtonItem *)item animated:(BOOL)animated completionHandler:(UIPrintInteractionCompletionHandler)completion;      // iPad
