How to Use Generator and How to Use Reader
First, import the following frameworks:
import BarcodeGenerator
import AVFoundationThen, use the generator to generate a barcode. For example:
RSUnifiedCodeGenerator.shared.generateCode("2166529V", machineReadableCodeObjectType: AVMetadataObjectTypeCode39Code)It will generate a UIImage instance if the 2166529V is a valid code39 string. For AVMetadataObjectTypeCode128Code, you can change useBuiltInCode128Generator to false to use my implementation (AutoTable for code128).
P.S. There are 4 tables for encoding a string to code128, TableA, TableB, TableC and TableAuto; the TableAuto is always the best choice, but if one has specific requirements, try this:
RSCode128Generator(codeTable: .A).generateCode("123456", machineReadableCodeObjectType: AVMetadataObjectTypeCode128Code)Example of these simple calls can be found in the test project.
To validate codes:
let isValid = RSUnifiedCodeValidator.shared.isValid(code, machineReadableCodeObjectType: AVMetadataObjectTypeEAN13Code)Use RSAbstractCodeGenerator.resizeImage(source: UIImage, scale: CGFloat) to scale the generated image.
Use RSAbstractCodeGenerator.resizeImage(source: UIImage, targetSize: CGSize, contentMode: UIViewContentMode) to fill/fit the bounds of something to the best capability and don't necessarily know what scale is too much to fill/fit, or if the UIImageView itself is flexible.
