有没有办法自定义 zbar sdk 相机视图。我使用下面的代码来添加扫描仪。

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];

我想做这样的屏幕。关联
