Customize scanner camera view zbar ios sdk

Question

Is there a way to customize zbar sdk camera view. I used below code to add the scanner.

ZBarReaderViewController *reader = [ZBarReaderViewController new];
reader.readerDelegate = self;
reader.supportedOrientationsMask = ZBarOrientationMaskAll;

ZBarImageScanner *scanner = reader.scanner;
[scanner setSymbology: ZBAR_I25
               config: ZBAR_CFG_ENABLE
                   to: 0];
 [self presentViewController:reader animated:YES completion:nil];

I wanted to do like this kind of screen. link
