  <pre><code>-(IBAction)QRscan;
      {       
          //Make sure we can even attempt barcode recognition, (i.e. on a device without a camera, you wouldn't be able to scan anything).
          if([SKScannerViewController canRecognizeBarcodes])
          { 
              SKScannerViewController *scannerVC = [[SKScannerViewController alloc] init]; //Insantiate a new SKScannerViewController
              scannerVC.delegate = self;
              scannerVC.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCancel target:self action:@selector(cancelTapped)];
  
              UIButton *button = [UIButton buttonWithType:UIButtonTypeInfoLight];
              [button addTarget:self action:@selector(settingsTapped) forControlEvents:UIControlEventTouchUpInside];
              UIBarButtonItem *infoItem = [[UIBarButtonItem alloc] initWithCustomView:button];
              scannerVC.navigationItem.rightBarButtonItem = infoItem; 
              scannerVC.title = @"Scan a QRcode";
              qrtest.text = @""; //Reset our info text label.
              scannerVC.shouldLookForQRCodes = YES;//QRCode Checker
              UINavigationController *_nc = [[[UINavigationController alloc] initWithRootViewController:scannerVC] autorelease]; //Put our SKScannerViewController into a UINavigationController. (So it looks nice).
              [scannerVC release];
              [self presentModalViewController:_nc animated:YES]; //Slide it up onto the screen.
          }
