Unable to scan Generated Barcode for EAN-13 family

[MishraVikas1]

Barcode generation is working pretty fine. But when I scan this generated barcode, no scanner is able to scan this.
Please suggest something asap.

I tried to generate one: 6901234567892 and it works as expected, the sample app could recognize it.

[CodeGen genCodeWithContents:@"6901234567892" machineReadableCodeObjectType:AVMetadataObjectTypeEAN13Code];

Could you provide your code?

One possible problem may you scale the image to fill the image view, you have to scale it aspect.
static inline UIImage *resizeImage(UIImage *source, float scale) will be helpful.
